Have you played with the manual controls, and your video card's control panel, to see if you can sharpen it up? I've heard that Dell's 21" CRT refurbs don't have the best track record, but a few people get lucky. Sorry you're having problems, and don't be squeamish about taking advantage of the return/exchange policy if you can't get a sharper image out of it. IBM's Trinitron refurbs supposedly have better quality and I'm considering picking up one of their 21-inchers from Azatek.com. IBM is really good about exchanging refurbs if you have a problem. Good luck!
