My MV540 screen won't change screen resolution

Specs: Windows XP
I hooked up my Dell Optiplex GX520 tower to my Compaq MV540 screen. The screen won't adjust to anything but the lowest screen resolution. I can go through the motion, but the screen blanks, and goes back to the low resolution. Any ideas?

The max resolution for that monitor is 1024 x 768 @ 60Hz, but the max "flicker-free" resolution is only 800 x 600 @ 85Hz.

RIGHT click on a blank part of your main desktop screen, select Properties (goes to Display Properties), click on the Settings tab.

What does it say there ?

What monitor on what specific video adapter ?

If it doesn't have a named specific video adapter, you need to install the specific
drivers for your video adapter

If it DOES have a named specific video adapter, but it says Default Monitor, or unknown monitor or similar, you need to change that to at least Plug-n-Play Monitor.

See response 9 here:

...starting at

"When you get to the desktop screen , RIGHT click on blank part of the main Desktop screen - Properties "

- OR -

When the monitor is connected to the computer, go to the Microsoft Update web page on the Microsoft web site and do a Custom Search.
Look in the optional Hardware updates, if any are found - if it lists the drivers for your monitor model, select that to install - it will download and install the specific monitor drivers AND it will set Windows to actually use them.

if your stuck on just one resolution, upgrade your graphics driver.
