Compatibility with Dell GX520 Optiplex tower and a Compaq mv540 screen

[cbeigle1]

HI there....

To get to the point, I'm trying to set the screen resolution and I can't do it. I go to settings and try to set to a higher resolution, but after the comp restarts, it just goes back to the low setting. Am I doing something wrong, or is it not possible at all? Thanks, in advance. Tony
