I found a discussion of this but could not figure out how to reply to that discussion, so I'm asking here. While working yesterday, suddenly my screen image downsized from the fullscreen 24" display to one where there are one inch bars on the left and right and about the same size at the bottom and top of my ST2421L monitor. Running Win 7 64 bit on Dell 570. Tried a factory reset of monitor without sucess.
Any suggestions? Thank in advance!
