I have a BenQ G2400WD monitor, and a vanilla Diamond Radeon 4870 512 MB. At some point after the screen went dark, I was never able to get my computer to work with the monitor's DVI input again. VGA works fine, but the picture is soft and blurry. Using a DVI to HDMI adapter to send the signal from my Radeon to my monitor's HDMI input works too, but the signal although digital is markedly different than with DVI. It's just too sharp and I can't change it no matter what I do, it strains my eyes a bit. What I found to be the weirdest of all is when I plugged by 360 to my monitor with an HDMI to DVI cable. With this configuration, the DVI port works on my monitor every time. I use like three different DVI cables to get my computer's signal working again with DVI but it's no use, the BenQ will always tell me that there's "no signal". This puzzles me quite a bit. For now I've set it to VGA but the picture clarity is quite inferior. I love the hell out of this monitor and consider it to be one of the best purchases I ever made as far as picture vs price goes, but I only wish I could get it to work properly. I'm suspecting that maybe my Radeon is the cause of this problem for whatever reason. Could a BIOS change/upgrade of some sort maybe help to alleviate this problem?
