I have a dimension 2400 and I recently reinstalled Windows XP. My monitor is on a default setting, 640x480 pixels.

I have a dell e773c monitor and I went to support.dell.com for the driver but it doesn't install anything after downloading. ?

I also tried to manually find the driver right clicked > display properties > settings > advanced > monitor but it won't let me click anything. It is just set to defualt.

I read that it might be possible to delete the default monitor driver and windows will recognize the correct driver?

Any suggestions? What do I do?

Did you RTFM on the driver download page ? -

You might try updating your video card/adapter first - http://www.mysuperpc.com/build/pc_install_monitor_driver.shtml

Awesome! I downloaded the video driver then the monitor driver. The page you linked was perfect. Thanks
