Sounds as if you need to locate and center the desktop using the monitor controls. Before doing this, make sure your system knows the brand and model of the monitor so it can optimize the display settings. You may need to find a driver for this as well. The driver defines the monitors capabilities such as resolution and refresh rates at various resolutions. Once you have matched the video card and monitor properly, you can adjust for best image and then center the display using your monitors own built in adjustments.
Okay, a dumb question here I know. I guess I'm getting to be a bit of a pest by now, I beg patience one more time. A video card I'm in need of indeed! But here goes my stupidity none the less. All things appeared to be working just fine, yep even my video card. Settings were set, and things looked mighty fine. That is until I decided to increase my Ram! It all went smoothly really....except my display settings. They are suppose to be set at colour-256 and resoultion 800x600. Well I can't seem to get them back, I keep getting a blue sceen with errors. So I set the resolution one setting below, and its great, well tolerable. Problem now is "HELP!?" my desktop has shifted over to the left and all is black to the right???? Don't laugh at me--how do I fix it??? Once again I'm lost. -Thanks
