Its replacement is a Dell Precision T5400, Xeon L5420 2.5ghz Quad Core w/ 12mb cache, 16gb ram FB-5300. It is upgradeable to a 2nd cpu, and these "L" Series CPU's only require 50 watts of power vs. the normal 75~100 watts. It currently has a Nvidia GeForce 210 1gb ram PCI-E video card.
While setting up the T5400 it was on a different 21" monitor running at 1600*1200 resolution. Once moving this machine to its new home, I was greeted to see this:
That machine booted up into Windows 7, and was just fine. Until I moved the screen resolution to its native 2550*1440, it then went pink and fuzzy again; dropping it to 1920*1080 it was fine. I knew the monitor was fine since it ran at full resolution on the old pc. I swapped out the DVI cable, same result. I swapped to the VGA connector (DB15), the picture was clear but maximum resolution was 2048*1150. Went back to DVI port on the video card, used a DVI->VGA adaptor, 2048*1150 was the result. Switched to HDMI, 1920*1080 resolution.
I tried five different video cards, and nearly the same results! Interestingly the ATI based cards show properly on post, only the Nvidia cards were fuzzy and pink at post. So I have ruled out the monitor, the dvi-cable, and the video cards as possible issues. It was starting to look like a flakey motherboard or something else strange.
A friend of mine mentioned that perhaps I need a dual link DVI cable. Huh? What is this dual-link you speak of?
