ahh major resolution problems

hey everyone,

ive been having some weird problems with a monitor I just got. its a Samsung SyncMaster 950b crt. the problem is the lower the resolution goes, the darker the screen gets. so whenever the resolution is around 800x600 or 1024 x 768, the screen gets extremely dark... so dark that i can barely see the pointer. and whenever the resolution is high, around 1600 x 1200, its okay. im not sure what to make of it. also, i noticed that raising the refresh rate from 60 to 65 made the screen brighter if that helps.

it sucks too cuz i cant play any full screen video games. the screen just completely blacks out whenever i open them.

if anyone is able to help me that would be awesome.

thanks.
