Nvidia DVI output quality ... not as good as ATI??

[imported_BIOSMonkey]

I have read several threads here (and articles on test sites) that indicate Nvidia's DVI signal doesn't quite cut it when it comes to driving high-res flat panels.

Well, I'm researching parts to build a new system, and have two Dell 2001FPs that need to be driven by a dual DVI card.

I am currently running them off a 9700 pro and a 7000 pci card, and the quality is fine.

But I am going to get a high-end PCI-E card that has dual-DVI ports. I was leaning toward Nvidia 6800 ultra until I started reading about a loss of signal quality (esp. on the second DVI port) at high res (1600x1200).

One of the threads suggested that higher tier OEMs may be using their own DVI output chips in their designs to circumvent this problem. Does anyone know whose cards have this design?

ATI has dual dvi, why not go with them?

I'm having no problems at all with the DVI output on my PNY 6800GT...current monitor is a Dell 2005FPW (1680x1050), and I've also used the 2001FP on it. It's my understanding that since it's a digital signal, it either gets there or it doesn't. None of the blurriness or double-image-ghosting that can occur over an analog (VGA) signal at higher resolutions and refresh rates.

Oh, and good luck on finding a high-end PCI-E card in stock anywhere...

resolutions that that problem occurs at is 1900x1200 and higher. If you only have 1600x1200, its a non issue, get any card that is cheaper.

Um, you would have a dual-link DVI port if you have one that can do higher than 1920x1200, and aside from the special cards ATi and nVidia created for Apple, there aren't any commercial cards from those two companies that have it. Workstation cards, yes, but thats a whole nother story.

I am running both a 2005FP and 2001FP off of my 6800GT (that has dual DVI) and I don't experience any problems.

I think this is one of those things that doesn't really matter. Sure they can run tests that show the signal from what nVidia uses is worse than that of ATi, but if you can't see it, then it doesn't matter.
