I have a no-name graphic card that Windows can't recognize, so it just shows standard VGA in the device manager list.

Now it just shows 800x600 and 1024x768, but I want to force that to other resolutions; I'm sure it supports because I checked in Linux!

You need to install an appropriate driver. To do so you need to determine if the GPU chipset is Intel, Nvidia, ATI/AMD (or on the off-chance other). Since you mentioned Linux, if you have a LiveCD handy, run lsmod | grep "^video " and report back with the driver that the linux distro selected. You could also use lspci | grep VGA to get the specific chipset. –  justbrowsing Aug 14 '13 at 10:21
thnx for your reply, my friend create this card and it doesn't have any brand like you say, intel or ati or ..., my question is how we can force to other resolution that's all ?! –  Sam Aug 14 '13 at 10:25

This is untried/untested, do so at your own risk!

Click on Start, then Run
Type in regedit in the Open box, then hit [Enter]
Expand down to HKEY_CURRENT_CONFIG\System\CurrentControlSet\Contr ol\VIDEO{Hexadecimal number for your primary video card}\0000
Note: Under VIDEO will be one or more registry keys that have a long hexadecimal number; this is the Hexidecimal number assigned to
a specific physical or logical video card. There may be more than one
if video cards have been changed or a major driver update has been
performed. The key that has the current setting should be the one that needs to be modified.
Double-click DefautlSettings.XResolution, change the Base from Hexadecimal to Decimal notation, and set the X axis.
Double-click DefautlSettings.YResolution, change the Base from Hexadecimal to Decimal notation, and set the Y axis.

Note: If settings did not take effect, modify a different video card in the registry
Note: If monitor ceases to function upon Windows coming up, reboot and go to Safe Mode. Pull up the registry and change the settings that were last modified back to the way it was or change the resolution to a safe resolution such as 640x480.


There are also tools which may help, like PowerStrip

Details on how to use it
