How do I check if my VGA card supports wide screen resolution?
Click your right button of your mouse on the desktop and click "Properties".
Then click "setting". If your VGA card supports wide screen, there would be resolutions like 1280 x 720 or 1280 x768 or 1440 x 900 or 1680 x 1050.
Most VGA card only support 1024*768 or 1280*1024 which will not provide best performance on wide screen.

For 20" wide, recommend resolution is: 1680 x 1050
For 22" wide, recommend resolution is: 1680 x 1050
