Widescreen 22" monitor won't stretch to fit screen

Without more details, it is really hard to provide assistance but here are some general items without knowing the model Monitor, the video card or the operating system you are using.

Generally (I can't know for sure without the LCD model) 22 inch LCDs have an optimal resolution of 1680 by 1050 pixels.

So the first thing you need to do is ensure that the video card display resolution is set to 1680 by 1050. If 1680 by 1050 is not an option in your display properties (In windows XP, right click the background, click properties, click settings tab, then slide the resolution bar to 1680 by 1050. Click OK) then try upgrading your video driver.

If that doesn't give you the 1680 by 1050 option, then your video card may need replacement with a better card.
