dual graphics cards, dual monitors, ati crossfireX

Question: dual graphics cards, dual monitors, ati crossfireX

i have 2 ati radeon hd 4850's. right now they are connected with the crossfirex bridges and i'm only using one monitor and running crossfirex. i'm thinking of getting a second monitor for better gaming/seeing more stuff in flight sim X.

what i can't find is how to use 2 monitors with 2 cards. do i remove the crossfirex bridges and connect one monitor per card, or do i keep the crossfirex bridges and connect both monitors to the first card, still running crossfirex?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: dual graphics cards, dual monitors, ati crossfireX

I would just connect the 2 monitors to the one card and then extend the desktop using either desktop properties or Catalyst control center.

Just taken delivery of a new computer. I have opted for two graphics
cards(256 Mb Nvidia Geforce 7800 GTX) linked with SLI for hoped for
improvement in handling large 16 bit files in Photoshop, along with
the 2 Gig of RAM operating in Windows XP Home.
The problem I have discovered is that enabling the SLI facility
disables the dual monitor display, leaving only the primary monitor
showing anything on screen.I use the second monitor to view Photoshop
tools and dialog boxes.Disabling SLI restores both monitors. I would
like to have both if possible! Is there a workaround. Both monitors
are plugged into one of the graphics cards.
Out of interest, I have timed applying radial blur to a 100 Mb colour
file, and it takes about 34 secs with SLI both enabled and disabled.
If SLI is disabled, am I only working with one graphics card?
Many thanks

I have a Samsung 530 Series TV. I also have a LG E2370 monitor. I am using a dual link DVI cable to use the 120 hz on my monitor. My 560 TI grphx card has a dual link DVI (which i use for the monitor), but NOT an HDMI output. The 560 TI graphics card has another Dual Link DVI connection, but my TV does not. Which means i have to use my onboard video which DOES have an HDMI, to use the Samsung 530 TV as a second monitor.

All i want to do is use my TV for when i watch movies and my monitor for everything else.

All i've done is go to display properties and try to do this from there, but the samsung TV just says "Check cable" which i've already done. Either that happens, or both monitors go blank.

Please help. Any assistance would be GREATLY appreciated. I built my computer.... Now i want to use my TV with it !!!

Answer:1monitor, 1tv, 2 different graphics cards. Dual Monitors..HELP!

Some motherboards allow you to use both onboard and a graphic card.
You need to look in the bios for a setting.
If not there then you will a "dvi to hdmi adapter"

dell xps 15 l502x laptop, running an intel integrated graphics card and an nVidia GeForce GT 525m dedicated graphics card. Also a VGA plug and play Dell IN1910N monitor connected through a HDMI to VGA converter to the laptops HDMI out port.

The problem
Each monitor is running off a separate graphics card, according the the nVidia control panel, which is fine, but they are each running the wrong one. The laptop by default uses the integrated graphics, and the external monitor uses the dedicated card, which is useless, a i really only use it as extra desktop space or for playing movies, which doesn't require the dedicated graphics. Then when i go to play a game on the laptop screen, it switches to the dedicated card AS WELL, which then struggles to keep up.
How can i set the external monitor to run on the integrated graphics always?
I don't care if the laptop screen doesn't auto switch, so long as it runs the dedicated card at the right times and doesn't struggle, like it doesn't when the other monitor isn't connected.

This image tellsme it should be possible, but i cant get it to work

So I just ordered an 8800gts to replace my 7800gts in Vista x64. I was wondering if keeping it and running my secondary monitor off of it would alleviate the stress aero puts on the video card when running dual monitors and gaming and increase my performance. Would I be better off keeping the 7800gts for the second monitor? Is this even possible?

Answer:Dual Video cards, dual monitors, and Vista game performance

It is certainly possible, you can use both cards at the same time, assuming your mob supports it.

I doubt if you'll see a huge increase in gaming performance, as aero essentially shuts itself off when needed (gaming), but it won't hurt anything either.

Hi all I no the title of this topic maybe hard to understand, basically im in the market to be upgrading from z77 to a newer z97 board, I have a few in mind that range from $180 all the way to $400, and when it comes down to it, it is the pci express lanes. I'm currently running dual 7970s and I noticed a lot of motherboards run 2x8x with dual video cards but some boards will run at 2x16x, so I was just seeing if anyone can tell me if theirs a big diff between running 2x8x and 2x16x with crossfired cards. thanks a bunch!

I am not the least bit knowledgeable on this subject. Are video cards the same as graphics cards?

I want to hook up two (or three) monitors to one computer. Not for games....just stock market stuff.
1. What will best serve my purposes at some reasonable cost? 2. What will be better for operation....PCI or AGP.
3. What is the difference between a regular PCI card and PCI Express and will the latter work in a regular PCI slot?
4. If I want 2 or three monitors, do I need a card with two cable connectors?
5. My computer already has a monitor connector, can that be used for a third monitor with two more monitors on a card?
6. Will the memory be important for my purposes or will I be well served just using a 16, 32 or 64MB card?

Sure would appreciate some explanations. Many thanks.


Answer:Video Cards For Dual Monitors

1. depends on whether you are building a new pc or installing the card in a pc you already have
2.pci-e is completely different, it has more pins and a different length slot. it also runs at triple the frequency of standard pci.
3.for 2 monitors the most straight forward thing is to use a card with 2 outputs. for 3 monitors i think you will need an SLI/Crossfire setup (dual cards).
4. possibly
5. if you are not gaming you won't need much memory. i would get a low range 128mb card like an FX5700

Hello everyone. I'm having a bit of trouble here setting up a dual monitor extended display between my desktop and laptop and I'll try to be as descriptive as possible.

Dell Vostro 220s Slim Tower (click for complete specs)
Windows 7

I installed a NVIDIA GeForce 9400 GT PCI-Express card and my main monitor is hooked to that using a DVI connector. This leaves the on board VGA port completely open.

HP DV6736NR (click for complete specs)
Windows 7
There is an open VGA port on this laptop.


On my desktop, the only display adapter listed in Device Manager is my NVIDIA card. When I plug the VGA in to each of the two computers, it is not detecting the other in my Screen Resolution opens. I think this has something to do with my on board video card not being active but I could be wrong. I hit CTRL+P and tried to scan for a detection that way and still nothing. I shut down my desktop (leaving the cord in) and my main monitor with the DVI connection just stayed black. I unplugged the VGA connection, booted it up again, and everything worked as normal. I believe I tried setting the laptop to projector only (hitting CTRL+P) to see if the desktop would boot to just the laptop screen using the VGA connection but that wouldn't work either. It just stayed black.

I'm all out of ideas. Can someone please help me?

Answer:Setting up dual-monitors using two video cards

You can only use 1 VGA output at a time, you cannot use both your GFX card AND your on-board. Also you cannot hook up your desktop with your laptop . You can however hook up your laptop or desktop to an external monitor (tv, monitor, etc) or to a projector.

Edit: In other words -
PC -> 2nd Monitor or Projector (Yes).
Laptop -> 2nd Monitor or Projector (Yes).
Pc -> Laptop (No).
Laptop -> Pc (No).

Having just upgraded from XP using the Nvidia dual monitor desktops for years, I was surprised to find Windows 7 has this feature in-built with the added bonus of slideshow desktop images C00L!
So beyond Win7 eye candy which is better, Does it come down to games running faster under the Nvidia dual desktops, what is the general preference here?

Answer:Is Nvidia dual monitors a poor cousin to Windows 7 dual monitors?..

afaik, there is no real performance difference, as all stuff is handled by the nvidia driver anyway.

And of course the more monitors the higher performance hit as there is more screen surface to work on (the same as increasing resolution).

Btw, the main pityfall of the multiple monitors is that the taskbar is only in the primary monitor, but there are a ton of good third party programs that can handle this, like Actual Multiple Monitors.

My question is:  when is Dell going to release a dedicated video card option that we can actually connect directly to these monitors without having to use converters/adapters etc??? This is nuts.

Hello All, 
 I have a XPS 8500 desktop I purchased it 2013 it works fine but I cannot establish how to run dual monitors with it. I have included a photo of the back as it does not match any thing that DELL show in their manuals. One the lowest point they have a VGA connection and two HDMI ports/ plug-ins. But only one HDMI has the receiving tab and the other one has nothing.
This leads me to believe I needed another video card? I am GUESTING because If I use the VGA to one monitor I get a desktop display. Then plugging in the HDMI lead to the other monitor has it duplicated, the same output on both.
From SETTING: System, Display, notifications, apps, power
 In settings the only way I get anything on both monitors. Is with / by selecting Duplicate on both. Any of the other three options I only get one monitor to show anything. I thought the purpose was to be able to have two different things going on, one on each monitor. It does offer another HDMI halfway up the consul with a tab for connection. When I plug a monitor into it, the screen shows "retrieving data" for a few seconds then outputs No Signal. It may be for an X-box of Play Station, not sure. Any advice...
Please see screen shots for back connections...the last photo is the lower area ports I have been using. The right HDMI port is different internally from the one that out puts a signal. This is what lead me to believe I need to have two video cards to run two d... Read more

Ok--here's the deal. I have an NVidia GT 6600 video card with dual monitor output. The problem is that I want my Plasma desktop to be bigger icons (i.e., 800 by 600) while keeping my flat panel monitor (the primary monitor for the computer) as a higher resolution since obviously we are sitting farther away from the Plasma and need those icons and text bigger. Now I can independently change the screen sizes with the Nvidia, but the problem is then on the plasma I only see about 60% of the screen of course because its keeping the same setup as the higher resolution but zooming in on it. In other words, for the desktop to fit in the plasma, it has to be the same resolution as the flat panel or at least close to that same resolution.

My MOBO has a slot for a second video card--will a second card allow me to indepndently set the resolutions so that I can actually re-arrange the desktop on the Plasma (i.e., the icons would have to go further horizontally and shorter vertically with the lower resolution.

Hope someone can be of assistance here (apologies in advance for the stupid questions)Ok I've just bought a 22" widescreen monitor and discovered my onboard graphics don't support widescreen resolutions (ie: 1680x1050). Also, I am getting a second, smaller monitor to set up dual monitorsI have one AGP and one PCI slot available (not PCI Express), very little cash, and lots of questions!1. Which is better (AGP or PCI) and why? I presumed AGP due to the speed and the fact that it's dedicated to graphics, but after googling AGP VS PCI, I found loads of people slating AGP saying they're really unstable, likely to crash your system, etc 2. Are most modern cards likely to support widescreen resolutions?3.1  Will it be easy to run 2 monitors off one card with 2 sockets (ie: 1 x VGA and 1 x DVI)?3.2  And if so is this going to be another factor that determines whether I go for AGP or PCI?3.3  If the answer to 3.1 is "Yes", will I be ok to plug 2 VGA monitors into it via use of the "DVI-VGA adaptor"?4. How does the installation process go? I plug the card in, plug the monitor into it and switch on? Will it be natively recognised or will drivers be needed? And if drivers are needed do you have to add the card first? And if so does the monitor still activate and allow you to see what's going on to install the drivers?

Answer:AGP or PCI graphics card - to replace onboard graphics AND set up dual monitors

I'm not saying they're wrong, but I've never had a problem using AGP graphics cards over PCI based graphics cards, but I'm just one guy, and I've never bought a "cutting edge" card.  I'm guessing people complained about AGP cards due to a variety of issues -- drivers, etc.

Answer:Dual Graphics cards SLI

It's just one cable from one of the graphics cards to the monitor. There's a bridge link internally, supplied with the motherboard, to connect the 2 cards. Also, there is usually some sort of adjustment to the motherboard to switch from normal to SLI mode. The motheboard user guide will advise on this.

Answer:Dual ATI graphics cards

you have drivers installed on your notebook for a discrete videocard. in other words, the drivers for the hd 4670 are for a card that installs in a desktop computer. the radeon xpress 200m is the intergrated video for the notebook. you need to uninstall the drivers for the hd 4670 and install the drivers from here: ATI Catalyst? Legacy Display Driver

i once had an acer notebook that had the radeon xpress 1100 graphics. i had to uninstall the drivers via driver sweeper @ guru3d (Guru3D - Driver Sweeper). if you have to use driver sweeper, everything is pretty much self explanatory. already have the driver for the xpress 200m downloaded so when you reboot, you can immediately install the driver.

Hi, I currently play League of Legends ALOT. I have a terrible Radeon HD 4600. I am thinking of getting duel GTX 560 ti cards, will this make a big impact on my gameplay FPS's? thanks for your help everyone!

Answer:Dual Graphics Cards

Hi and welcome to TSG.

It may make a significant difference to something like LoL, however it is also massive overkill. One GTX560 ti will easily run LoL on max settings.

Having said that, there are also other things that you MUST consider before upgrading.

1) Is your current power supply (PSU) good enough to support the new card? This is one of the most important things to look at and also something that is often ignored.

2) Your current system may be a bottleneck for a better card, in which case you are potentially wasting money on a card that is being held back by the system in other areas.

What is the exact make and model of model of the PC, assuming its a pre-built system like a HP, Dell, eMachines etc?

If it is a self / custom build what is the make and model of the motherboard, CPU, RAM, power supply etc? The more info the better.

Hey everyone,

I've always wondered how good it would be to run dual graphics cards.

Can anyone offer some pros and cons for running dual graphics cards, say dual nVidia GeForce 9600 GT's, just for an example

Also, If I ran a reasonably new graphics card like the 9600 with an older 6600 would my performance suffer? Does it try to run the older graphics card first? How does it all work?

Would it be worth just buying a top of the range graphics card to run on its own? because it would be cheaper from where I'm sitting to run dual graphics cards.

I know this is a lot of questions, so answers to any of the above is appreciated.

Thanks in advance.

In the interests of thread environmentalism I have searched around for an answer to this but haven't managed. Feel free to direct me to a good link with the information I need.

I'd like to know about dual cards. I currently have a single Geforce 7900 GT/GTO (does anyone know whether the 'GT/GTO' is significant or what it stands for btw?) 256mb card. I remember when I bought the PC I was told I could upgrade to dual cards at any time - so I guess there is an extra port (apologies if my thinking or terminology is incorrect, I'm keen to learn, so please correct me ).

Does the second card have to be identical (or is it advisable), or does it just have to have the same amount of memory (I seem to remember this is a good idea with cards (?) of RAM)?

I assumed a 7900 nowadays would be dirt cheap, but this is the cheapest I've found so far at 70 (assuming its the same one, I find it a little difficult to tell ) but admittedly I'm not sure where to look so perhaps you could advise me on that score (I live in the UK) too.

Finally what can I expect in terms of graphics improvement? I assume it would be more than a simple increase in RAM. I.e. to what extent is it worth making this upgrade?

Many many thanks!

I have an Asus P5N-E SLI mobo and an 8800GT installed - all works fine.

I want to run three screens using SoftTH so have to install a second graphics card (not in SLI).

With the Asus, it has a little daughterboard that needs to be reversed to allow the second PCI-E slot to work for graphics (SLI or Not SLI) - it basically splits the 16x channel into two 8x channels.

So, with the daughterboard in dual graphics card mode, when I put the second graphics card in the PC refuses to boot. I get a beep code error (1 long 3 short beeps) which indicates a graphics failure. If I remove the second 8800 but leave the daughterboard set for two graphics cards, I get the same problem.

Switch the daughterboard for single graphics and the single card works fine.

I'm looking at buying a new custom computer (probably from Digital Storm.) I can't decide if it's practical to have dual high end graphics cards or if a single will be fine. I would def. like to get a nvidia 8800 gts or gtx, but is it really necessary to have a dual setup? Or should I just put the money into more RAM or better cooling? Thanks so much!

Answer:Dual vs. Single Graphics cards

Alot depends on the application of your hardware.

Some considerations:

What is the native resolution of your monitor? Alot of modern LCD monitors are designed to look best at a specific (and typically high) resolution. You would need alot of GPU power in this case, and would likely benefit from an SLI or Crossfire configuration.

What are you doing with the computer? Modern games and 3D CAD modelling applications need alot of GPU power as well, and would be suitable candidates for a dual-GPU configuration.

I recently installed a second graphics card to get triple monitors, but the second card is giving me the "Error 43" message. Both cards are GeForce 8400 GS (one PCIe, one PCI). I am not attempting to run SLI or anything like that, just want the triple. In the device manager, both cards are listed, but the 2nd one has the yellow error icon on it. When checking the details, they both have the same version of the driver. I am running Vista Ultimate x64.

Where am I going wrong?

Answer:Dual Graphics cards error

Can you run two cards without SLIing them? Didn't know that Where did you get the drivers from? Try to download them for the nvidia website.. Search that error code in google, see what other people have come up with.

Is it better, or even possible, to mix different graphics cards with a mobo as long as both are crossfire ready? Or is it more wise to stick with two of the same graphics cards if your going to run duel graphics cards.

Answer:Same dual graphics cards, or mix and match?

I know some people who say they run duel cards, It seems to be a very good thing. But I have heard of them only running 2 of the same, Not 2 different ones.

Hi everyone,

I recently purchased a new computer (Windows Vista Home Premium) that has an ATI X1300 graphics card with 1 VGA and and 1 DVI output. I have 2 monitors with DVI inputs and my old graphics card laying around; an ATI Radeon 9250 with 128MB of video memory. I plugged the old card in with the new card and I do get the old one to work, but the new one is disabled by Windows Vista due to a driver conflict (eror code 43). Is there a way to get both of them to work at the same time? Thanks in advance for any suggestions!-Kevin

Answer:Dual Graphics Cards Issue

Welcome, You can't make the 2 video cards to work, because one of the driver is different and thats why its a conflict. If installing 2 different video card drivers then maybe your new or old may cause an issue.

Hello folks!

I am running a dual display setup at my work. One monitor uses a DVI connection, the other VGA. As we are firewalled, and work has some automatic software that installs, I have a feeling that something causes my dual monitor system to "break". Here's what happens:

Problem: I boot up the computer, and only the primary monitor is working (which is my DVI connection). Signal is SENT to the other monitor (it never goes to sleep for lack of activity), but it stays black. The power indicator light flashes between green and off, and I can move the mouse/windows over to the black hole that is my secondary monitor (though I can't see the cursor or anything else there).

Temporary Solution:
1.) I pull up the HD Intel Graphics App from Control Panel. I go into Display-->Multiple Displays-->Single.

2.) Then, I pull up Device Manager and delete the Intel HD Graphics Adapter (though I leave the driver on the computer when prompted).

3.) I restart the computer. At this point, it reverts to the VGA Adapter in the Device Manger. However, right clicking and selecting "Update Driver" prompts the computer to search for, and install, Intel HD Graphics.

4.) I restart again. Then, I pull up the HD Intel Graphics program, select Multiple Displays, and Extend, and sha-zaam! I'm good to go.

However, this only lasts until I shut down the computer. Then, it reverts back to sending my secondary monitor a signal, but it stays black.

I want to use dual monitor features of Windows, I have a GeForce 3 Ti200 in my AGP port, and when I plug this in I think it disables my onboard graphics.Is there a way that I can have the onboard graphics and AGP card in use simultaneously so that I can plug-in 2 monitors and then use the dual monitor feature?I read this from another website regarding this: "Multi-monitor and onboard video cardsThis should work fine. If the onboard card is PCI, it will become the secondary card, if it is AGP it will most likely be the primary. Depending on your BIOS, it could also be possible that the onboard video gets disabled as soon as another VGA card is in the system."But I'm not sure how to stop it disabling the onboard video?Any help appreciated

Answer:Dual Monitors - AGP Card & Onboard Graphics

Hi - I'm not sure you can actually do this - as one compensates for the other.Onboard graphics is supplied as a generic on most PC's nowadays, and it is up to the end user to replace these with a new card.How old is your machine? Most new boards and BIOS's pick up an AGP card and shut off the onboard display - mine does this, and its less than four months old.As for two graphics cards i.e. the card and onboard - I don't recommend this, it will cause problems in Windows and make life awkward for you. That's why the onboard is suspended with a new card.You might want to consider buying an adapter that allows you to have more than one monitor from your graphics card. I am not sure of this, so you may want to check, a KVM switch may be the answer - I AM NOT SURE OF THIS...Final point, when you install any new card into a PC you remove the old one and any drivers to avoid conflicts. It's the same scenario with your graphics card.

Hello there, Johnathan.

I'm not a Multiple monitors guy. but i'm pretty sure that you can connect them like that:


I guess is possible because the purpose of adding another card to you rig is somehow related to the fact that you want to add more monitors (of course, this is only one of the reasons for multiple cards), hence, you need extra ports for connecting all the monitors. hehe Somebody please correct me if i'm wrong

Firstly DON'T USE UPPER CASE IN YOUR THREADS ........ IT MAKES IT DIFFICULT TO READ AND TO SOME PEOPLE IT LOOKS LIKE YOUR SHOUTING.OK now onto your problem Your Dell is, with all due respect, a budget desktop system. Yes it has a Intel Core Duo processor but it's still classed as a budget system.Your graphics card is a NVIDIA GeForce 8300GS with 128 Mb of it's own RAM ( so it's not sharing any with the PC itself ) but as Dell say it's the strength of the actual signal that's the problem.Just because you have two graphic ports does not simply imply you can connect a monitor to each. It's a bit like a house wiring system. In your typical three bedroom semi the downstairs wall plugs are probably supplied by a 30 amp ring main, those upstairs by another separate 30 amp ring main. You could have 12 or more wall sockets downstairs but you could not plug in and switch on 3 x 10 amp heaters plus your TV into the sockets without blowing the fuse box or circuit breaker ... the same goes for the output power of the graphic stream.

I have two identical graphics cards, X and Y. Each one feeds two monitors, X ->1 and 2, Y ->3 and 4 respectively. Monitors 1 and 3 use DVI, 2 and 4 use HDMI output. Monitor 1 has until recently been my primary/default monitor (both as set in Windows, and the one that displays BIOS info and motherboard splash screen at bootup.)

I was having problems getting monitor 3 to display properly - Windows only recognised it as "generic pnp" and either wouldn't send it a signal (so black screen, even though it was showing its power on light) or it would display at the wrong resolution. So I swapped the DVI cables of 1 and 3, whilst keeping monitor 1 my Windows primary monitor. Now, monitor 3 displays at the correct resolution (but is still seen as generic pnp by the PC). I suspect there's an EDID problem somewhere, or maybe a cable problem (though I've changed the cable to monitor 3) but at least the monitor displays when it's meant to, and at the correct resolution.

As I only use four monitors when using certain applications I normally keep 2, 3 and 4 switched off unless I use them. But since swapping the DVI cables around, all the BIOS and WIndows starting graphics display on monitor 3, though the Windows login screen still comes to Monitor 1. As Monitor 3 is often switched off, if I have a problem during bootup I won't know now as monitor 1 stays blank until the login screen.

Dual width cards usually cover up an adjoining slot because
they have a large cooler that sticks out or connectors on

It is twice as wide as a standard card.
It doesn't need 2 slots to connect to,it just needs the extra room

Hi all,

I'm having some issues with extending my desktop onto a secondary monitor correctly. I have an HP Elitebook 8460p with a Radeon HD 6470m graphics driver, and the Catalyst Control Center installed. I've hooked a VGA-VGA cable into a Dell monitor. I can successfully clone my desktop onto the second monitor, but I cannot typically *extend* my desktop to use dual monitors.

I've tried extending it using Function-F4 and selecting extend, going to the desktop->Display, selecting the monitor (it is recognized) and clicking "Extend", and going through the Catalyst Control Center to Arrange Monitors, clicking on the external, and clicking "Extend". In all cases, the screen flickers to black, and when it comes back, my monitors are still in "Clone" mode. In fact, even if I've selected to only use the laptop or only use the external monitor, on clicking "extend", it goes back to "clone". I do see that when I select "extend" in the Catalyst Control Center, it *very briefly* shows me both monitors in its configuration area, but then flickers back to a single monitor (the laptop).

I've reinstalled Catalyst Control Center's latest software/drivers to no avail.

I know how to uninstall and install drivers but since I have two I'm honestly a bit confused. If you can't tell already I'm new to this stuff. I've thought about this for a long time and this is actually my last resort. I've gone through google for hours looking at guides but can't quite find an answer for what I'm looking for.

-Do I simply uninstall both drivers for the graphics cards? (I'll use dc pro to help clean out those drivers)
and when I do that when I start to install the drivers do I just install it once or do I have to somehow install the driver twice and set it on the graphics cards?

Answer:Solved: Installing drivers for dual graphics cards

Are you using two cards to support 3 or more monitors, or are the cards in a Crossfire setup?

If the cards are separate, uninstall the drivers using Add and Remove programs, shut down and remove one of the cards, then boot and install the drivers. After the first card is working, then install the second card.

If it's a Crossfire setup, are the cards jumpered properly? And other issues can cause the drivers to crash. Power supply issues, motherboard BIOS and/or setup also come to mind.

Hi there,
I need a bit of advice. I currently have a 24" Samsung monitor with my Dell Inspiron 570. I am thinking of buying another 24" monitor so that I can have a dual screen set up.
However, (please excuse my ignorance here) I have just been informed that before I buy the 2nd monitor that I also need to buy a graphics card to enable me to work the two monitors as my PC only has one socket for one monitor.
So, I was wondering if anyone could help me decide which type of graphics card to buy. I intend buying a 2nd hand one from eBay. I am NOT a gamer so I won't be needing anything too flashy but I'm open to ideas for something quite decent.
My current system reads thus:

4.00 GB RAM (3.75 GB usable)

After looking in Device Manager, it appears that my existing (built in???) Graphics card is ATI Radeon HD4200 - whatever that means.
Someone did suggest buying a Radeon HD4350 but again, this means nothing to me and I don't know whether:
a) they are any good, and
b) it would be compatible with my Dell Inspiron 570.

Is it possible to use the vga and display port simultaneously on the T500 for two 1920x1080 monitors?  In this situation the internal monitor would be powered off, with the laptop potentially in an advanced mini dock. I've searched the forums but I haven't found a definitive answer to this question other than using a usb2dvi converter or the advanced dock with an ATI x1300.  This would all be in Windows XP. Alternatively, is it also possible to use both the dvi and display port outputs in the dock so that I can connect both monitors with a digital signal? Thanks


Go to Solution.

Answer:Dual WUXGA (1920x1080) Monitors T500 with Discrete Graphics

1) When you are in the advanced mini dock, the displayport is active, so is your VGA and DVI. I am using the displayport on the laptop driving a Dell U2410 at WUXGA resolution, and the DVI port on the dock is driving another Dell U2410 LCD.However, if you have a switchable graphics card and you switch to intel gpu, then the dvi port on the dock is disabled, only the the vga would work.2) To your question of your the laptop's vga and displayport driving these monitors the answer is yes. The VGA on the T500 should be able to drive a WQXGA (not recommended as the picture quality is heavily degraded) and the displayport can also drive WQXGA.

Or should i just be able to set the monitor up manually to best cope with the VGA input.
All thoughts welcome :)

"Dual 2GB GDDR5 NVIDIA GeForce GTX 580M ? SLI" vs "Dual 2GB GDDR5 AMD Radeon HD 6970M CrossfireX"

I want to buy an alienware and get confused on the video cards. Which really is better among these two? They say that since nvdia is more expensive it really is faster or better. Confusing part is they are both 2gb gddr5. Is it just the brand or the performance? I read also that Dual NVIDIA GTX 460M 1.5GB GDDR5 Graphics Card in SLI is faster than Dual 2GB GDDR5 AMD Radeon HD 6970M CrossfireX, is this true?

Right now im considering amd radeon dual 2gb just because it's "2gb" and cheaper than nvdia dual 2gb. But maybe it is better to get the dual nvdia 1.5gb, I still dont know the exact price differences and if it is worth it. Please help. Many thanks.

Answer:"Dual 2GB GDDR5 NVIDIA GeForce GTX 580M SLI" vs "Dual 2GB GDDR5 AMD Radeon HD 6970M CrossfireX"

I would say 580M's because most games are coded round those cards with physX and CUDA ect ect......

Hi all just wondering whether or not I can hook up two Galaxy Gtx560 1gb Cards to my Asrock h61M/u3s3 ?

Answer:ASROCK h61M/u3s3 is it compatible for dual graphics cards ?

That would be a negative; only one PCIE 16x slot available.

Best case scenario would be you selling the 560 and picking up a 590 if you wanted SLI.

okay, having trouble dual monitor setting up my cousin's pc. in the device manager, under display, it shows ATI Radeon HD 3200 Graphics, and, ATI Radeon 4200 Series. now. I tried to setup a second monitor to it through vga, but it didn't detect the second monitor. monitor is fine. the original wasn't detected in the second one either. stays in power saver mode like it is plugged into nothing.

i am too a picture to show you the back of the pc. i know what to do once the monitor is detected, to enable the small greyed out second display in the display settings, but only ONE monitor box is shown.

much help would be appreciated =)

(the old monitor is plugged in to the left, and below, the lone bga port is the one we are trying to use.)

Hi everyone, I am new to this forum and I'm seeking help to setup dual monitors with my new ATI RADEON 9250 from NewEgg. I have an AOPEN motherboard with an onboard graphics card (Intelr Extreme Graphics Driver I came upon this thread and I saw he had trouble installing his ATI card. I read that, and I went to Device Manager and I disabled the Intel controller. Then I shut off my computer and installed my ATI card without any problems. I booted up the computer and installed the drivers successfully. But I had one problem - dual monitors. I wanted to set up one monitor hooked up to my onboard intel card and one monitor to my ATI card. When I clicked properties on my desktop > settings, under the display I saw *screenshot 1* (attachment) I was hoping to see Intel and ATI but instead I saw 2 ATI. Now I know that on the ATI card theres a secondary plug for a second monitor but you need an adapter to it. The adapter would be my second way out, the first way out is to set up the second monitor to the Intel onboard card. When I went to device manager, I only saw 2 ATIs, the Intel disappeared. I tried installing drivers again but it gave me an error.. *screenshot 2* shows what I just said.

i've never tried to hook up dual monitors before so its probably something simple. i installed a new graphics card a while back and haven't used the original for months, and now that im trying to hook up dual monitors it wont even recognize the original in the device manager, or that i have a monitor plugged into it. both monitors work perfectly fine in the newer card slot. any assistance would be appreciated. thank you for your time.

Answer:computer wont recognize original graphics card for dual monitors

You can't use your onboard video card and an add-in card at the same time, it's one of the other. Well you can, but only on motherboards that support hybrid CrossfireX. In most cases your onboard video is disabled when an add-in card is detected by the BIOS. To use dual monitors you will have to have a video card that supports it and connect both monitors to that video card. Then press the Windows key and the P key to extend your desktop onto the second monitor.

EDIT: Filling in your system specs would help.

Hi All I have a T530 with Intel HD Graphics 3000 and a Mini Dock Series 3. I've done lots of googling, but I can't seem to find out: 1. If this hardware supports dual monitors.2. How to setup dual monitors with Windows.3. How to setup dual monitors with Linux. Can someone help me at least with 1, please? I've tried connecting 2 monitors to the docking station. One VGA and one via a VGA convertor to the DVI-D port. Windows seems to half detect the monitor on the DVI port, but I can get nothing out of it. Fn + F7 isn't helping me much either. ThanksPaul T520 (love it) & Mini Dock Series 3


Go to Solution.

Answer:T530, Mini Dock Series 3, Intel Graphics & Dual Monitors

1. Yes, that is without the internal LCD on. But you can get more screen support (> 2 screens), if you use displaylink usb video adapters (i.e. ThinkPad USB 3.0 docks), or use a displayport to dvi, vga, displayport splitter (i.e. Lenovo displaylink splitter). 2. DVI-D is a digital video only video output port, so it won't support a simple DVI to VGA adapter, only a DVI-I port does. If you need another VGA port, you would need a Displayport to VGA converter. 3. Same issue as above, it is basically you got the converter wrong. Once you have the displayport to vga converter you should be fine.

Hi guys, new and in need of help please.

Probably a basic problem to most but struggling here.

It has Windows 7 & a GeForce GT240 1024MB graphics card

I cannot get my 2nd monitor to work with a new PC I had last week. The DVI port seems to be the problem.

Both monitors work independantly through the VGA port fine, no problems, but neither work through the DVI port when I use a simple DVI to VGA adapter, I have tried 2 of these just to make sure it wasn't a dodgy adapter.

I have followed the various windows 7 'set-up dual monitors' tutorials but with no luck.

Nothing happens at all when I plug the 2nd monitor in.

Any thoughts?

Could I need to download a driver or anything?

Thanks for any help.

Answer:Problem setting up dual monitors with 7/GeForce GTS240 Graphics Card

Does that video card support DUAL VGA monitors? What I'm getting at is, is that DVI connector on the video card a DVI-I or DVI-D? If it's only a DVI-D (Digital only) the DVI to VGA adapter won't work. If it came with the DVI to VGA adapter one would assume it is DVI-I (integrated, digital and analog).

EDIT: I just tried a DVI to VGA adapter on my 220GT and it worked OK. This card has 1 VGA and 1 DVI conector. I'm running 2 VGA monitors as I type this. To be honest I was not expecting this to work.

I would like to add a second monitor to my set up without a significant expenditure.   What is the maximum screen resolution that I should consider buying for the second monitor?  My set up: Dell SP2309W 23" monitor running at 2048 x 1152 (max res of monitor) through the DVI.Mini dock with a T500 with an ATI HD Radeon 3650 switchable graphics card. How best to connect it?  I am guessing that to add another monitor to this set up, I would be attaching through the VGA port.  I know VGA can be blurrier than digital, so if there is an inexpensive option to run the second display off some kind of digital connection, that would be great. Thanks

Answer:Dual External Monitors - T500 w/Switchable ATI HD 3650 Radeon Graphics

you can get a usb2dvi converter, and this will support another monitor at similar resolution.

My Dell Optiplex 990 SFF has an Intel 2000 which I'm learning is no good.  I hate that my screened looks super stretched vertically and no matter how much I play with the resolution I can't fix it.  It's hurting my eyes. 
In addition I wanted to set up dual monitors with extended display.  While it's detected, identified, and showing the desktop on both monitors it's in duplicate and I can't get  the extended display to work. 
I'm no good at computers and have spent HOURS trying to understand all of this.  My guess is that I need to upgrade the graphics card?  I feel like I can do this from a youtube video.  I'm just not sure what I need.  I don't think I need anything fancy. Just something basic that will let me do the dual monitors with extended display and address the stretchy screen problem.  Recommendations?  

Answer:Dell Optiplex 990 SFF Graphics Card & Dual Monitors with Extended Display

Maximum power consumption for SFF is 25 Watts the best card the machine could operate with is:
VisionTek Radeon HD 6350 SFF Low Profile Graphics Card - 1 GB DDR3
From what I understand that card is not very powerful but might be enough to operate multiple monitors in low resolution

I now have two monitors set up on my computer. One is using the VGA output, and the other is plugged into a DVI to VGA convertor in the DVI port. I have a Radeon 9600 Pro video card and am running Windows XP Home.

What I want is to extend my taskbar across onto the second monitor. Even better than that would be to have a second, independant taskbar which displays only programs open on the second screen. The first screen's taskbar would show programs open and displayed on the first monitor.

Any ideas?

Answer:Dual Monitors, dual Taskbars?

Guess what I found?

Exactly what I was looking for

Actually, not exactly. I was hoping for a native Windows solution that doesn't require running another program to get the second taskbar.

I'll clarify my question: Is there a way to get a second taskbar on a second monitor using options or features found in Windows XP? Failing that, does anyone have any favourite programs they'd like to suggest?

Answer:dual monitors / dual programs set up

Hello dunna, welcome to Sevenforums

With a laptop, (assuming you have an HDMI port), it shouldn't be too difficult. However, laptops are different. For example, mine, you plug in the secondary monitor, and there is a function key (Fn) that you press, and the corresponding key to change the output mode (for me, it is F1). It should let you choose how you want to display to the monitor. Test it out yourself to see, but if you can't find it, let us know. It helps if you provide the laptop type, so we can tell you the keys exactly

Hi,My setup includes dual monitors with a T61 in port replicator  and a Dell 24" monitor positioned above.  While I can achieve this setup by manually dragging the external monitor above the laptop each time I dock, I cannot get the Presentation Director to capture this position accurately.  It will capture the setup, but reverts to horizontal monitors with left/right mouse whenever the captured profile is used.   [With my old T43 in the same setup, I was able to get the monitor positions memorized correctly. ] Does anyone have a solution?  I've checked the Control Panel--> Display settings and the NVIDIA Control panel.  The control panel allows me to set up the external monitor as per above, but I haven't found any control to ensure the settings "stick".

Answer:Dual Monitors / Cannot capture vertical monitors (mouse up /down vs left /right)

Additional Note:  I've also tried creating a new profile in the Presentation Director with the selection for "External Monitor positioned above laptop", but that does not work as it will not recognize the external monitor resolution of 1900x1280, and thus will not allow me to finish the profile.

Hi there guys and girls,

I just have a quick question that I'm looking for an answer for.

I've recently been given a shiny new video card, which is awesome as I've only ever had onboard video on this PC. It's a Radeon 9800 Pro 128MB. I realise it's not the greatest video card in the world (just because I can't afford to buy one doesn't mean I don't know what's good ), but it's free, and I rarely turn down free things.

Anyway, on to the point.

As some of you may know, the Radeon 9800 has 3 ports. VGA, TV, and DVI. I wish to set up a dual monitor system, but all the monitors I have sitting around are analog (VGA). I thought, no problem, I have a VGA port on my motherboard, and I can use the one on the video card.

Alas, I've been playing around for a few hours, and I couldn't seem to find a way to do it. So I do what I usually do when I need an answer. I hit google. Found tons of dual monitor tutorials and faqs, but none of them mentioned anything about onboard.

My question is as follows:

Is it at all possible (even if it requires some slight hacking) to set up a dual monitor system using one VGA port on the video card and one on the motherboard?

If not, is there a VGA to TV or DVI adaptor I'm able to get? If so where, and at what price (I'm in Australia ). Or can you think of any other way I can do this cheaply? .

Or does anyone have a spare VGA-DVI adaptor or video card sit... Read more

Answer:Dual monitors with 1 dual video card and onboard video

Well AFAIK you can't dual-monitor with and I/O card and onboard video. Its one or the other. However I know you can get DVI-to-VGA adapters. Those might work for you so long as the card supports dual-monitor (no time to check right now).

OK, I'm almost embarrased to ask this but - I currently use Cakewalk Guitar Studio 2 and Surreal Systems Synth Software for a home recording studio.  Old, but comfortable like an old pair of shoes.Cakewalk GS2 requires the use of W98 with NT4.0 and will work with new versions of Windows as long as NT is in there, apparently it's not with Vista since I can't even install it using the Compatability Wizard, not sure which Windows versions it will work with after W98, though.  Surreal will only use W95 or W98, not certain if it requires NT as well.I'm comfortable using W98 for this but one of the drawbacks is with using a single duplex soundcard - audio already recorded will not play back when recording new audio tracks.  I've checked and checked and while there's full duplex cards out there that allow playback and recording of audio at the same time, none of the newer ones will work with W98.My question is this - if I just add another single duplex sound card that's compatible with W98 (probably an external card), is it as simple as then choosing one of the sound cards for input/recording and the other for simultaneous playback?Ideally, I'd love to find a full duplex external sound card that functions under W98 so that's a possibility as well if anyone has any ideas or sources.Thanks for any help you may be able to give me !

Hi! I just upgraded to Win8 this weekend and so far I really like it. I discovered something this morning that now that the weekend is over is bugging the crap out of me and I need help. I work from home and use this alot so it would be helpful.

I am trying to do a couple things I could easily do in 7,
- have Chrome open in both monitors at once with different things on them.
- currently Chrome has no minimize/maximize buttons on the upper right like it used to. Makes it very hard to multitask.

Greetings all.

I'm having a slight problem figuring this one out. I shouldn't, but this problem is kicking my rear. I've got two AOC monitors set up for a client, yet they don't actually portray a "stretched desktop" over the two monitors. It Displays one "widescreen image of my desktop on the right monitor, and what looks like a fullscreen image on the left. I've gone through the usual setup for dual monitors...

Change Display Settings ->
Select 2 in the monitor selection screen ->
Select "Extend" in the other option menu.

I've tried "Windows + P" and tried it that way too.

I've made sure they're the same resolution and an display hertz are the same. I hope to the Gods that this is an easy fix and one of you will have a quick solution for me, but I've gone over all my specs and I just can NOT figure it out. Its usually an easy setup, but for some reason, I'm stumped.

I'm new to multi-GPU but would love to get into it. I currently have a PowerColor Radeon HD 4890. Would it be possible to CrossFire this with a Radeon HD 4870 x2, getting three GPUs of power and a grand total of 3GB of GDDR5 graphics memory? I know my PSU can take it as it is an 800 watt gaming series.

Also, how much of a performance gain might I expect to see by doing this? I found a great condition Radeon HD 4870 X2 2GB for $100. Even if it doesn't CrossFire it'll be a beast on its own anyway I bet.

you should crossfire the 4870's x2 x2 lol be like 4 gpu's that would be crazy fast

I think there is a way to do this where i have seen boards that can crossfire 4 gpu's so i dont think it would be that hard just have to get the support i will look that up and see if there is some information on this

try this out i think your better off doing the 4870 deal with three of them

Hi guys, I've just built my first PC and I was thinking about trying the XfireX thing.
My Mobo is an Asus P8Z68 V-LX with an Intel Core i5 2500k cpu and 8Gb ram.All speeds are stock.
It has an AMD Radeon HD4890 1Gb graphics card inside now that works with LucidLogix, but that only plays a few games, so I was wondering if I could run this in XfireX with an AMD Radeon HD4850 512Mb graphics card. Both cards are DirectX 10.1.
I was thinking, could I use the 1Gb card as the primary PCIe x16 card and the 512Mb card as the secondary PCIe x8 card.
Or do both cards have to be exactly the same ?

If this is possible to do, or even if it's not, how do I power 2 graphics cards if they both have 2x6 pin power inputs, and my new Corsair CX600 psu only has 2x6+2 pin plugs ?(both of which are plugged into the HD4890 card)
