Was wondering if anyone else on TR is using an HD 79X0 with a Dell 30" monitor.
I've been using a 3007wfp-hc with an HD 7970 since about March. I'm plagued with intermittent garbled images. The best way to describe it is like trying to watch the old analog cable premuim channels that you didn't subscribe to (but that's not really very accurate). Basically, I intermittently get weird shadows, hazy garbled images - sometimes to the point were I can barely discern what's on the screen. It seems to occur more often prior to Windows loading - and has made many BIOS adjustment attempts a real PITA. Once in a while it also happens in Windows (7 x64) - though I have yet to notice it in a game when in full screen 3D mode.
It seems to be a weird DVI-D handshake issue that may be particular to this monitor as I've not heard about it with any other. I'm curious to try a display port to DVI-D adapter to see if the problem persists, but haven't yet shelled out for one of those (the only one I can find is the Apple one and it's a bit pricey).
Also, I'm not the only one who's encountered this, it seems. There's a thread
about the issue (or at least a very similar one) on the Asus forums. Here's a pic
from that forum showing a POST screen with the issue (my issue gets even worse than this sometimes, with the whole screen going white in addition to the type of garbling seen in the pic.
The HD 7970 has performed flawlessly in every other regard and even overclocks well. I don't notice that I get any other graphical glitches either that would suggest a faulty card (in the usual sense). My old HD 4850 with the same DVI-D cable, etc, did not produce this...
Just wondering if anyone else has run into such an issue?
