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?
