Can't change resolution
Many months ago I saw in display properties under the settings tab where it
said "Extend My Windows Desktop onto this Monitor"..I put a check mark in the box and played around with it,unchecked the box again and clicked apply,I thought everything was ok...Now I'm unable to change my resolution...the checkmark is still there and it's grayed out,so am unable to make any changes...before this I was able to go up to 1280x1024..now I'm stuck on 800x600..any ideas....would entering Safe Mode and trying that work?? |

that message occurs on systems with two monitors fitted, to either 2 adaptor
cards, or to a 2 headed video adaptor check the back of the case for a second video port and plug into the other one if there is, If not use device manager to remove the video adaptor and allow windows to redetect the adaptor -- Adaware http://www.lavasoft.de spybot http://security.kolla.de AVG free antivirus http://www.grisoft.com Etrust/vet/CA 12 Month free trial (till Feb 2005) http://www.my-etrust.com/microsoft/ Etrust/Vet/CA.online Antivirus scan http://www3.ca.com/securityadvisor/virusinfo/scan.aspx Panda online AntiVirus scan http://www.pandasoftware.com/ActiveScan/ Catalog of removal tools (1) http://www.pandasoftware.com/download/utilities/ Catalog of removal tools (2) http://www3.ca.com/securityadvisor/n...aspx?CID=40387 Blocking Unwanted Parasites with a Hosts file http://mvps.org/winhelp2002/hosts.htm links provided as a courtesy, read all instructions on the pages before use Grateful thanks to the authors/webmasters _ "Manticore" wrote in message ...

If you are sure that your video adapter card is capable of that extended
resolution and if the option doesn't appear then the driver you are using is not the correct one for your video adapter. Confirm the exact make and model of the card installed in the machine, then get the right video driver for it from the manufacturer's www site and install it according to their instructions. The option to extend the desktop onto a second adapter is not relevant, unless you are using a video adapter card that is actually two devices and includes an option to allocate both devices to one monitor. However, if that was the case the option would not be grayed out (unless, of course, you are running the wrong driver, as above). -- Jeff Richards MS MVP (Windows - Shell/User) "Manticore" wrote in message ...

Well,before I put a check in that box...I was able to change
resolutions....I know I have the right drivers for video card,I haven't changed them in a long time.....Whenever I try to change to a higher resolution...the screen gets bigger,that is to say.....I have to scroll up,down,left and right to see the whole desktop,it makes it appear to be a larger screen..I had one reply telling me to remove the video card from the device manager and letting Windows redetect it,but am sure if that would do it or not....I remember when I messed with it and checked the box,it showed 2 monitors on the settings tab..one actual and one virtual..as I stated before...I played with it and removed the checkmark,clicked apply and forgot about it till just last week when I tried to go to a higher resolution and was unable...I checked Microsoft web site and read something there about 3rd party software for display..I do have a Blaster Control tab on my Advanced button in display properties.... any other ideas??? thanks for your reply "Jeff Richards" wrote in message ...

So you are saying that you do have the option to select the larger
resolution, and you can select that option and the resolution is changed correctly. However, the image is now larger than the display area, AND you get an option that allows you to scroll the image back and forth within the display area to see the whole desktop. This is rather different than suggesting that you can't change the resolution. The video adapter card driver is operating in a mode that is often used for LCD or similar screens that do not display well at anything other than their physical pixel resolution. You need to look for a setting somewhere in the video adapter card settings applet (perhaps under an advanced option) that puts the display into the scrolling mode. It might be labelled as LCD mode or similar, or it might be called 'Virtual desktop". Since this feature is specific to the video adapter card you are using (or possibly controlled by an add-on utility you have installed) it is not possible to be precise about where this option is or what it is called. It could even be a separate video display management utility. It's also possible that it is controlled by the monitor you have selected - check whether your monitor is identified as LCD or flat panel - this setting might force the adapter to use the virtual display mode. -- Jeff Richards MS MVP (Windows - Shell/User) "Manticore" wrote in message ...
