Booting/CMOS Setup using external USB Display Adapter

Question: Booting/CMOS Setup using external USB Display Adapter

The screen is shot on this machine --I have a USB to VGA adapter, but can't get it to activate. Because I have no screen I can't go through the typical Driver install .... is there a way to force the system to boot to the USB Display adaptor? thx in advance!

Preferred Solution: Booting/CMOS Setup using external USB Display Adapter

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: Booting/CMOS Setup using external USB Display Adapter

Hi there @DMillerassociat, Welcome back to the HP Support Forums! I understand that you are looking for a way to use a display connected using a USB display adapter as your boot display. I am happy to give you a hand with this. I do not believe that this is currently possible, for several reasons. First the system BIOS would need the ability to recognize the USB port connection as a standard video connection. You would almost certainly need to either disable or disconnect your existing built in display, and you would also need the drivers that make a USB video adapter work installed. If the BIOS does not recognize the device as a valid video device inherently you will never get a display, when you need to get into the BIOS setup. I hope this makes sense, and if it does answer your question, please mark this post as a solution. Kudos would also be appreciated.

I have a lenovo thinkpad with Win XP professional. I got a bot infection(userini, wpv may be others) recently. Sme guy manually cleared some, but the wpv infection was still seemingly thr. The computer still crashes sometimes and thne takes multiple attempts to restart even in safe mode. I wanted to change my OS to help clear the trouble, but now the thinkvantage button which is supposed to get me to the BIOS interface is not functioning and shows a BIOS shadowed error. What if anything can I do personally to try and get the thing to work.

I used to have the videogame Medieval 2 Total War on my new alienware laptop and it was fully functioning. I ended up deleteing it because I thought it was taking up too much space. Now I can install it but when I try to run the actual game I immediately get a message saying "Medieval II Total War has encountered an unspecified error and will now exit" and after reading through forums I saw a comment about someone having this problem and fixing it by downloading the latest ATI graphics.

I think I might know the problem but I am clueless as to how one goes about fixing it. A few days before I found out about this site and managed to find the virus that was slowing my internet, I was quite frustrated by the slow loading speed of my internet so I opened task manager and began ending random processes, I realize now this was not a good idea. I think I may have done something to ATI.

When I try to run the ATI setup (which has been on my computer the whole time), I reach the ATI Display Driver when it tells me "Setup did not find a driver compatible with your current hardware or operating system" then after clicking OK i received the message "Try to setup your display adapter with a standard VGA driver before running setup"

Surely this can't be this difficult. My W500 is docked in the advanced mini-dock connected by DVI to a 20" monitor. At boot nothing is displayed on the external display. I can't get anything on the external display until after Vista has booted and I have logged in. How can I see the boot process and the login screen on my external display?Todd 

Answer:External display while booting?

You need to change the Boot Display in BIOS.Go into BIOS, (F1 at boot), Config > Display > Boot Display Device and select DVI, should do the trick for you.

Hey everyone, it's been a long time since I've had to ask anything on these forums, but I'm glad they're still here when I need them! I've done some looking into the problem, and it seems like there aren't many resources on my problem.

I'm trying to connect my television to my laptop, via an SVideo connection. The problem is, my graphics card does not, and CAN NOT, have its factory/updated drivers installed. The graphics card is currently being run under "Standard VGA graphics adapter" drivers.

(The reason I can't put drivers on the card is because it's fried. I'm suffering from a burnt-out, defective NVidia GeForce 8600M GS, like many other people, and I'm mired down in court documents that I'll be using against HP in small claims court.)

Are there another set of drivers I could try that would allow my laptop to use an external display?
Is there a way to set up an external monitor under standard VGA graphics adapter drivers?

I am using a usb-c to hdmi adapter to output to a TV but the black levels look washed out. I had no issues with the same TV and a previous laptop that had a dedicated hdmi port. In the intel graphics settings usually there is a "quantization range" setting to change color space between RGB Limited and RGB Full if the intel graphics is driving the hdmi port. However, in this case, there is no hdmi port but instead a usb-c to hdmi adapter, thus the quantization range setting is missing. I've had the same issue before on a previous laptop with usb-c. I've tried installing thel atest drivers, including the non-validated ones from the intel website, but none give me the quantization range setting.

When I boot up without a connection to an external monitor I experience some display issues with text sizing of certain objects within certain applications (e.g. Microsoft Visual Studio).  In these applications parts of the User Interface display perfectly.   Other parts of the same application will have vastly oversized objects and text.  And, in another application the text is greatly undersized in certain portions of this app. When I boot up while connected to an external monitor everything displays perfectly on the external monitor.   This happens without making any changes whatsoever to system display setting or application configuration settings.  If I disconnect the external monitor the X1's internal monitor still displays everything perfectly.   But if restart while disconnected from an external monitor I experience the same display issues as described in the 1st paragraph. I don't think this problem was always there, but  I cannot say for sure.  It just got so annoying that I finally decided to write to the forum today.   I would guess that the problem has been this way for 1-2 months. The Lenovo System Update app tells me that everything is up to date.    Is there some setting or perhaps driver that needs to change? Tim

My MO-BO is a Gigabyte 990FXA-UD7, and I've noticed the CMOS display is showing FF. If there is a 'h' after, it's blocked by my graphics card.The MO-BO manual states that FF or FFh is "Boot attempt (INT 19h). It doesn't explain what that means. Cheers, In advance =)Now, this board has an onboard Reset Switch (RST_SW) and CMOS Switch (CMOS_SW). The manual says the latter clears CMOS values.So, what does 'FF' means exactly, what could have caused it, and does it have any negative effects on performance?Build:990FXA-UD7AMD Phenom II X4 925 2.8 GHz (Quad Core)2 x 4GB Corsair Vengeance2 x Gigabyte HD6870 OC

Answer:CMOS POST FF(h?) on CMOS display.

FF is related to 2b and appears to be graphics card related, this was taken from a web page:"2bWhen the system powers on and the Debug LED shows the usual POST code sequence but hangs on 2b or you get a beep code as soon as the sequence reaches 2b, then the Mainboard cant detect your Videocard properly. Note that the POST code sequence might not halt at 2b but continue, so the final POST Code it displays could be FF, 00 or 7F which means the Maiboard booted, entered BIOS, or OC recovery kicked in and is waiting for Input to enter BIOS. Since the Videocard couldnt be detected properly you will only see a black Monitor and either 2b, FF, 00 or 7F. Check if there is something wrong with the Videocard, the PCIE slot or BUS, the Monitor or monitor cable. Turn the Monitor on and off, switch the Monitor cable from one D-SUB or DVI plug to the other in case your Videocard has two. If this doesnt help then reboot and load the optimized defaults. If that doesnt help either try another Videocard if possible, or try the Videocard in another system to make sure its working properly. Try another monitor or try the Monitor on another System."Googling is quicker than waiting for an answer....

It is not that obvious, but if you show a white screen, or most of screen is white, and you check it carefully, you can see that horizontal jitters. This only happens in external display, not happen in the laptop display. I also have a T420, but I didn't see this problem using VGA to connect with external display.  Does anyone find this similar problem? I doubt whether this is problem about VGA port, or the related driver.

I just traded in my old parts for a whole new system and was in the process of putting it together last night. I got to startup and solved some minor problems, but now the darn mainboard wont detect me hard drives. I figured out that this is probably solveable by formatting the drives, but I do not want to do that until I back up some files from my primary drive to my secondary. So the only other way is to manually detect the drives in CMOS. However, when I open the correct page for my primary drive, it will not let me input the data needed such as the capacity, cylinder, head, precomp, landing zone, sector etc. How do I access those fields?
Also, my hard drives do not have the information printed on them that I need and I no longer have the owners manual. Does anyone know of a site that will give me ALL specs on my hard drives?

Answer:CMOS settings wrong F1 to run setup

Does it happen to say anything more specific? Like which CMOS setting is wrong? Some computer complain even when you change the peripherals like remove a PS/2 mouse.

What if you actually press F1, load the defaults in there and save the settings? There may be several kinds of defaults you can load.

If it still keeps forgetting the settings even after replacing the battery (with a new one I hope (and the new battery is the right type and is making contact)), then it may be the motherboard that has gone bad. Not much you can do about that.

Maybe try updating the system BIOS in the very unlikely case that it is some BIOS glitch that corrupts the settings..

Answer:Help.....I'm frozen in CMOS Setup Utility

First things fist, you may just need to remove the hard drive you just installed and put the computer back to it's original configuration and try to boot (assuming you were able to boot before). If this does not work, you may have done something to your Bios/CMOS. You should have the option to clear the Bios/CMOS via a jumper on the mother board. I would look for the User's Manual, this will tell you where the jumper is. The other thing is to go to the Manufacturer's website and download the manual.

Hi There,

2 days ago, for no reason my PC, on startup went to the CMOS utility setup page, and will go no further. There were no hardware changes, and, unless there were any windows updates, no software changes made. It just boots up with the initial Gigabyte screen then straight to the CMOS screen

The clock is showing the current time and date, so I guess the battery is ok, but I didnt think this would be it since the machine is only 7 months old.

What steps can I take to try and determine if its a mobo fault or a processor fault.

It may be of use to know that i reset the CMOS using the jumper on the motherboard in order to fix another problem.

Any help would be greatly appreciated.

Thankyou enlightened folk.

Answer:CMOS Setup opens without request

Might be possible the delete key is sticking on your Keyboard, try to clean or try another Keyboard.

Boot up go into bios/Cmos setup, Check all settings adj as needed, If you have option in Bios too Reset Configuration Data enable it, then make sure you save & exit.
Here is Free Bios Guide to help with most settings:

One question, you reset Cmos to fix another problem, What was the other problem? if the above doesnt solve, just woundering incase original problem might be related?

I apologize for what may be considered very basic questions but I want to make sure what I'm doing is done right and I don't screw anything up.

This is my first PC build and I was able to hook up all my components and everything just fine but now I'm at the CMOS setup have a few questions. My motherboard is a Gigabyte GPA-890-UD3H.

1. There is a new BIOS version for my mobo. Should I upgrade to it first or load my Windows 7 OS first and then upgrade after? When updating the BIOS version does it revert back my settings in the CMOS to default settings or keep the profile I have them save under? Can I even upgrade my BIOS prior to OS installation if I don't have a 3.5 floppy drive or a FAT32 USB flash drive?

2. I'm running a OCZ Vertex 2 SSD as my boot drive and I've read that to optimize it I should be running on AHCI instead of IDE. Is this the preferred way and do I need change the OnChip SATA Type on my mobo to AHCI, the Onboad SATA/IDE Ctrl Mode, or both?

3. I also have a 1.5TB Caviar Green HDD.that I will be using for my data storage. Since this is a SATA drive I shouldn't have any problems with the AHCI setting should I?

4. I have 3 120mm fans (2 system/1 CPU) plugged in to my mobo, if I don't want them all running at max what and how should I be adjusting that. I have a Smart Fan Mode I can set to Auto, Voltage or PWM.

5. When I go to load Windows 7 and I select the SSD as my boot drive it only shows with 55.9gb vs the 60gb a... Read more

Answer:Help with Window 7 install and CMOS setup

1. Totally up to you. You can upgrade the BIOS before or after, most mbs these days will let you flash the BIOS from a HDD (just don't do it in windows) if you don't have a 3.5 or usb drive.

2. If you're going to switch to AHCI, do it before you install the OS. It makes life easier.

3. Nope, should be fine.

4. Depends on the mobo. Can't comment on that one.

5. All drives are marketed as 1000x1000x1000 as a GB, whereas it should be 1024x1024x1024

6. Yes

Answer:Re-setting cpu frequency in cmos setup

there should be no reason to set CPU frequency (also known as FSB and multiplier) in your BIOS unless you are an experienced overclocker. (also not recommended.)

Ok, I just unplugged all my computer hardware and moved it from my old case to my new one, aswell as putting in a new 80 gig Hard drive and a new 1 gig stick of ram. At first when I attempted to start the computer it said it had a bios error and I should insert a system boot floppy disk, but when I put in my boot disk it would just read and not do anything. So then I decided to try and jump my CMOS Jumper, that seemed to work, and the computer started up like normal, except it said the Cmos data was cleared and default was loading, and I should recustomize it. I decided to leave it at default, and loaded windows, did the normal Email check, then shut down the comp. I then discovered later, that the Comp would power up, but not load anything, not even go to the load up screen. I then decided to try jumpin the CMOS, then the comp started fine, and it now seams, to get the comp to start and run, I need to rejump the CMOS before starting up the comp.Any Help Is greatly appreciated.If you need exact Comp specs just let me know.

Last week I suddenly couldn't start up my laptop as usual after hibernating it for a day. Here are the specifics first of all:IBM Thinkpad T40p80GB HDD1GB RAM1GHZ Intel Pentium N ProcessorWIn7 UltimateAt first I attempted running a recovery (repair), it started well, but never ended. Tried starting up the laptop following the different F8 settings (last known best config, normal settings, debug). I even tried going into system restore via safe mode, but surprisingly there were no restore points to be found. The repair then worked once, and the PC booted up to the desktop level, then I heard a sound like "crr" and the screen froze up. Trying to re-start never worked, the IBM splashscreen never came until I tried changing the CMOS battery. After changing it, the splashscreen now starts, but hangs there for quite a while (20 secs), which is not normal. Then it tells me "checksum error, change date and time". I press F1 to enter the setup (which it does), and whilst I am entering the time, the whole thing simply shuts down. Tried beating it several times now, but it still shuts down. It even shuts down if I do nothing after the checksum announcement. Is the CMOS battery flat already? Or is it something else?Grateful for any help.

Answer:After CMOS change, laptop shuts down during setup

Have you always run Win7-Ultimate on that?  It doesn't seem like the hardware configuration would support it. replacement battery is probably bad, too.#19 in the diagram the CMOS battery & measure the voltage, should be 3.0VDC.

i just bought my Satellite U400-12p 2 weeks ago.
I checked my cmos setup but its asking for password.

Anyone knew what is the password given by the manufacturer?
I tried phoenix as a password but its not accepted.

Thank you guys in advance

Answer:Satellite U400-12p - cmos setup asking for password

Do you mean the BIOS password?
Well, it?s really strange because the BIOS password is not set.
It should be clear!

I don?t know what happened with you notebook but if the BIOS password is set and you don?t know this password then you will be not able to clear it!!

Only the ASP (authorized service partner) can remove such password.
So if the password is unknown -> go to ASP

This is everything what you can do!

Replace the battery. It will cost something like 1-2 quid, and is just a simple operation of pulling the battery out, going to some store, showing it and saying that you need a new one, then putting the new one in.

After noticing my system clock was not keeping the correct time on a Packard Bell iMEDIA X2415 desktop running XP Pro, I removed the battery and went out and bought a new CMOS battery, which was a direct replacement for the original battery, after fitting the battery I restarted the system which then gave me one of those blue screens which we all love! with the error code 0x0000007B, indicating an inaccessible boot device, the rest of the blue screen code is (0xB84c3524,0C0000034,0x00000000,0x00000000) which, after a little research, indicates a device driver problem. In the standard CMOS setup the Primary IDE master is not detected, it is a SATA drive anyway, under advanced setup, the first boot device is the DVD drive, and the second boot device is my hard drive, listed as PO-ST3500620AS, so the system is recognizing the hard drive but cannot access it. I loaded Ubuntu linux from the DVD drive to check the condition of the hard drive which came out as an uncorrupted NTFS file system. I'm thinking, if it is a corrupt driver file, then replacing the driver on a system that will not boot could be problematical. I'm sitting here wondering how all this hassle could come about from a simple CMOS battery change!
Any help with this problem will be gratefully received.

Hello, I would love to ask for some help!
I've recently purchased the newer Dell XPS 13 9360 Non-touch (not the 2 in 1) and am having some trouble with using an external monitor. The screen (on the external monitor) keeps on flickering and has a very unstable connection. 
I've searched and found that apparently lowering the power output of the WIFI network adapter can fix this problem. 
The problem is that the current XPS's wifi adapter doesn't allow the power output to be changed. The previous fixes were geared towards intel wifi adapters.
The general power settings for the computers doesn't show wifi card power controls.

I have updated all the drivers for the computer including the wireless adapter. Still the options doesn't change.

Has anyone found a way to get a stable external monitor to work with the Killer Wireless Adapter cards?
Any help would be greatly appreciated!

Answer:XPS 13 9360 External Monitor Flicker with USB C - HDMI Adapter [Killer Wireless Adapter]

For what it's worth: For me (XPS 13 9360, QHD, i7, 16 GB, Killer WiFi), external screens are perfectly stable, even with wireless being on relatively high throughput load, albeit not high power (energy) load.
I am connecting both HDMI and DisplayPort displays, each with cheap native USB-C adapters (i.e. through Thunderbolt). I also have full success with a Dell DA200, through its built-in HDMI graphics adapter.

You are the original owner - Right? How ole is it? After everything else, this error would men the hard drive or its controller has gone bad. Often it is the hard drive, either because of rough treatment or overheating.  More often overheating. The hard drive typically does not get enough coiling. Yet most hard drives will take it. They can run  to 85 C and still work.After all is said, you are at the point of trying a new hard drive. If you have already made regular backups of you system and data, all you need to do is get another drive. Do not try to format the hard drive. If some of recent data is there, you may wish to get it back.Do you have a recovery method ready to use?

We may be able to find directions to reset your cmos to factory default.

On some mb's removing the battery is the best way.
On others, there are a couple of pins on which you can place a jumper.

Pulling the battery out often does not reset cmos. Try this method.
1 Unplug the power cord from the pw supply.
2 Now push the on button 2-3 times. This removes any residual charge from the pw supply caps.
3 Open the case and clear cmos with the clear jumper for a min of 30 seconds.
4 Put jumper back to where it is supposed to be, replace pw cord and power on system. Enter the bios and load defaults, save settings and restart.

If that does not work, pull out the second video card and repeat the clear procedure.

The battery on the motherboard is probably dead. It's a coin-shaped and -sized silver metal lump on your computer's motherboard. Pry it out (make sure the computer is off and make sure you don't break anything) and take it to your local electronics/computer/watch store. They should be able to give you a replacement.

Answer:Armada E500 CMOS external pin.

Hi Blue,

Your idea of a rechargeable battery is good but it is not worth the trouble. Use two Alkaline AA, AAA or similar cells. The circuit uses so little current that the batts will last as if they were not even being used. That is about 5 to 8 years if they are fresh when installed. They can be soldered to if you use a hot (about 30 watt) well tinned iron and do the job quickly. I use a little non-acid soldering paste to speed the job. If you need more info feel free to ask.

Good Luck, Jim

Welcome to the Sevem Forums, Oraz.

If you still have the DVD of Windows 7 home edition and if it is also 64-bit then you might find the graphics adapter driver there which might get installed. Otherwise try installing Graphics Card AMD Radeon HD7570 in Windows XP SP3 mode.

It came to my attention that the USB port that allows powered off charging was not functioning. I figured it merely had something to do with the BIOS, so I went in and  enabled the function on the port. However, after the system rebooted, no boot screen appeared then the system began to hum extremely loudly, and shut itself down. Everytime I restart the system now nothing appears on the screen, no beeps, nothing. I had the battery fully charged and the AC adapter plugged in when I changed the CMOS settings. Also, prior to making changes to BIOS, I had all of the latest Lenovo updates (including BIOS updates) on the x120e itself. What was the cause of this issue, and how will I be able to resolve it? Is there an easy fix to this, or will I need to send it into Lenovo to conduct repairs?

Hello there.
I'm having an issue with my HP pavillion G7. I've had errors in the past with the screen, which I replaced myself. The replacement was successful until a possibly unrelated CMOS error began to appear. I also had a bad battery which was replaced. The 502 cmos checksum invalid error appears at boot at times, once I reset it though it usually boots in windows and the clock is messed up. The computer usually would just turn on and display a blank screen. I decided to replace the cmos battery, but this didn't help.
It still is displaying the error, mixed in with a blank display at other times. I've also tried resetting the bios and updating it... but still no avail.
I'm not sure whether or not this is a hardware or a software issue. I'm willing to reformat my hdd if necessary. 

Anyone have any suggestions on how to fix this?

Each time I start up settings in display properties resets to
Screen resolution 640 X 480
Color Quality low 8 - bit
I rest them to
1024 X 768

apply and restart and they reset to the above.

The correct monitor and Adapter are selected.

I ran a update search for each and it says I have the latest driver version.

If I need to update the monitor and Adapter driver what version and where do I need to go?

Any Help would be appreciated.

My AST Premmia MX P/60 (first gen pentium) computer is missing the CMOS battery pack. The battery pack configuration consists of 3 AA rechargable batteries. I Use to have the battery pack put removed it a long time ago because it was bad and I misplaced it. The problem now is finding a replacement. I decided to use a 3.6V battery pack from a cordless phone but I have to determine which pins to connect the battery too. There are 3 pins, 2 close together and 1 by itself. I don't want to connect it backwards. I tried using a volt meter but I can't really get any good readings. All 3 pins give me a reading of what looks like .83 millivolts I believe.

I have a Dell Zino HD media desktop, and it all of a suddent showed this error on booting up:
CMOS checksum error, F2 to Run SETUP, F1 to load defaults 

The thing is, I can't get it to move past it. I've tried 3 different keyboards, many restarts, and nothing gets it to move past this screen.
How can I overcome this?

Answer:Dell Zino: CMOS checksum error, F2 to Run SETUP, F1 to load defaults - Can't Move Past the Screen on Start Up

Unplug the system and hold the power button for 30 sec.  If that doesn't get the system to POST, the BIOS/CMOS is corrupt - replace the mainboard.

Built it 2 weeks ago, and around a week ago my PC randomly freezes, forcing me to hard power off. Clearing the CMOS can sometimes give me a couple freeze-free hours, so I did it like usual. This time, I am getting no display after clearing it like usual. I asked the PCMR discord about the random freezing, and they said it's probably my motherboard.Specs:Ryzen 3 1200, stock clock right now, I did try to OC it but it got to around 80C so I got scared and turned it off and cleared CMOS, and another time I *censored* up and put it @2.4V for 0-10 seconds.GTX 1050 Ti OC edition, never overclocked it though after my bad CPU OC experience2x4gb 3000Mhz RAM: Tried to put it in XMP but had some problems, so it's at stockMobo:Asrock AB350M Pro4 googled it, and apparently other people have had problems with this freezing.

Hi all, got around to playing with the ultrabay today, but I've run into trouble and Google has been no help. I wanted to install my old laptops HDD in the ultrabay, which I did.  It reads in CMOS no problem, but it is not recognized in any way that I can see in Windows.  I tried Disk Management, etc but it doesn't show up anywhere.  To clarify, this is the HDD out of my old laptop (Win7). Suspecting that perhaps the Ultrabay cannot work with ancient spinning technology, I popped in an extra SSD (Samsung 840 120GB) I have and tried that in the Ultrabay instead.  Same result.  Displays in CMOS setup but not in Windows.  Not in Disk Management, nowhere.  This SSD was formatted on a Win 7 system.  My y510p is the one with the 1TB + 24GB SSD. Can anyone help?  I really need to get at the files on my old HDD!! Thanks in advance

Answer:y510p - Ultrabay HDD/SSD reading in CMOS but will not display in Windows

Fixed it through this youtube video: Worked like a charm, both HDD and SSD detect perfectly now.

after changing battery i.e cmos battery the comp is not booting.a red LED blinks with no display on the monitor

Answer:Computer wont Boot after CMOS Battery Change. no display

Something must have happened while you were inside the case. Do you hear any beeps when you start it up? If so describe them--long, short, how many. Did you disconnect or remove anything to get to the battery? If so are you sure you put it back together correctly?With the power cord removed open the case again. Make sure any add-on cards are firmly in their slots. Make sure the cpu heatsink is correctly attached and the ram sticks firmly in their slots. Make sure the power connectors to the motherboard are tight. Then start it up again and see if you get a display.If you still get nothing remove the power cord again and remove any unnecessary add-on cards and temporarily disconnect the drives. Remove any USB devices. Then reconnect the power cord and start it up again. If you now get a display then likely one of the removed devices is at fault.

 I am working on an old Acer Aspire 5610 laptop for a client, with a 1.66GHz Intel CPU and 3GB DDR2 RAM installed, and the display is always dimmed, in BIOS / CMOS Setup as well as in both Windows and in Linux.  RAM was recently upgraded from 512MB. New DDR2 RAM is from Crucial / Micron in Idaho, USA. I checked the BIOS / CMOS Setup settings but there does not seem to be any "brightness" settings there-in.  I've re-installed Windows XP 32-bit from scratch, into a bare / empty NTFS formatted  partition, and am about to hunt down and install drivers in hopes that one of them may resolve the problem in Windows, maybe, if I am lucky. But if so then I may still be stuck while running Linux, specifically, at the moment, openSUSE 12.3 32-bit. I may also try Linux Mint.  My client is a Linux Newbie so I want to give her dual-boot capability between Windows XP and Linux.  The laptop has a 120GB HDD so I shoe-horned in a 10GB NTFS Windows XP partition.  I am also using an external VGA display, 17" flat  screen, via the D-Sub-15 VGA port on the back panel and the VGA display there has full brightness. Just the built-in LCD display is constantly dimmed, even in BIOS / CMOS Setup. And it does not seem to matter whether the external VGA is plugged in or not. I thought of that and retried a cold-boot with NO external monitor attached. I also tried changing the RAM size allocated in the BIOS to the Video between 128MB and Max-something. No ch... Read more

I had to reinstall windows 7 on my acer aspire 5560g laptop, I installed the drivers on the Acer site. I found the legacy updates for my cards and installed them. And I am still having problems.

The monitor is not showing the native resolution of 1366 x 768, it's topping out at 1024 x 768, it's refusing to let me use the built in screen savers. It's supposed to be a duel graphics system and the device manager lists two under the display drivers. Both are listed as standard vga display. One with the little yellow exclamation mark. It's driving me nutty. Can someone help me?

On a side note, the slider for screen brightness has also gone missing, and the fn brightness control doesn't work either.

Answer:Display adapter now listed as standard vga display

You are missing the graphics drivers. To save you some time here I gave you a link:

I have a W500 and recently bought a 22 inch lenova monitor 2551p. Catalyst Control Center does not display a Fixed Aspect Ratio option for this new external monitor. I can change the resolution to a fixed aspect ratio on my native screen, but not on the new external monitor. Long story short, a 1024x768 webpage gets stretched across my widescreen monitor and it should not - I should see the black bars on the sides. Is there a resolution to the issue?Does anyone have a direct URL to download and install new drivers?Does anyone have a direct URL to get the latest and greatest Catalyst Control Center?Is there third party software I can use in the place of Catalyst Control Center? I am pretty sure I have all of these things, but want to see if someone knows a work around or newer drivers/software.

Answer:W500 Does Not Display Fixed Aspect Ratio for External Display 2551p

 i am not sure whether the Lenovo LCD that you got, has the fixed aspect ratio and 1:1 mapping option. If it doesn't then there is nothing much you can do from the LCD end.
Which catalyst driver are you using right now?

Having a very strange (and annoying) issue with the display. I can only see the display on my Twist after connecting it to an external monitor first. If I do not, all I see is a black screen. No cursor, no anything. If I connect it to an external display via the display port to VGA adapter, it works fine. If connect it to an external display and then disconnect my external display, the display will remain on the Twist. However, if I reboot, I lose the screen again until I connect it to an external monitor. I made sure that "PC Screen Only" is chosen in the Fn+F7 option. This is obviously a serious problem. This is for company use and our users will not have a VGA monitor handy with them where ever they go. I checked the hardware manager and all the drivers are installed with no warnings.

Answer:Lenovo Twist display issues - No display unless I connect to an external monitor

Figured out a work around and narrowed down the problem. If I hit the Second Screen key (F7) after booting, it will go PC Only as the first choice and bring up the display on the laptop after a few seconds. The puzzling thing is why it seems to choose the external monitor as the default monitor on boot, even if it is not conected. I've tried running System Updater to make sure that I have all the latest drivers. All the display settings appear to be correct.

Hi, I own a T420s 4171 and have 2 external monitors hooked up to my docking station. That works fine, but when I try to also display my laptop screen (as my 3rd screen), it won't enable it. It seems to only allow 2 viewable screens (2 external monitors OR 1 external monitor + laptop screen). I tested a T420s 4173 and was able to get 3 viewable screens, but not my 4171, even after updating all of the lenovo drivers. I was comparing video card specs (4171 vs 4173) and it looks to be the same. Can someone confirm/deny that I'm able to have 3 screens with my model? Thanks.
