Have you tried a different cable? Or is it built in to the monitor? Is it a dual-link DVI-D cable?

I've only tried single link because that's all I had laying around. Could it be the cable if I have the same cable working with no drivers/other gpu?

Always worth a try.

What type of DVI cable would be most ideal? It looks like this monitor has DVI-I and DVI-A pins blocked anyway not leaving me much choice.

Well in general trying any other cable that fits is worthwhile just to rule it out.

Tried another cable and had the same result

AFAIK, it is a known issue on later Nvidia cards with integrated TMDS

Sorry, I'm new. Why does using windows standard drivers or a DVI to VGA adapter not also trigger the issue?

Evidently the NVidia drivers have a bug (or a feature) that the Windows standard drivers do not. VGA signals are completely different from DVI and it is not surprising that they would produce different results.

The bug is specific to the Nvidia drivers which interact directly with the card hardware to offer accelerated rendering (2D and 3D). The Windows standard drivers use the non hardware accelerated VESA BIOS interface of the card and are less likely to have such bugs because they are much simpler in functionality .

when using a passive DVI to VGA adapter (the most common kind) on a DVI-I port , the video is not actually being converted from digital DVI to analog VGA . The VGA signal is already present on the video card, being generated independently of DVI, and is exposed on pins of the DVI-I port that are not used by the DVI digital connection . The passive DVI to VGA adapter simply connects the VGA specific pins to a 15-pin VGA connector . The bug being specific to DVI , it does not affect VGA output .
See https://nvidia.custhelp.com/app/answers/detai … dvi-i-and-dvi-d for more info on DVI-I .

Thanks so much, that's a great response. Is there much chance of this being solved in the future?

That would depend on nVidia's enthusiasm for fixing the bug. Considering that other thread is three years old, I wouldn't hold my breath.

A long, long time ago I worked around a rather different bug in nVidia's drivers by editing my monitor's EDID. Maybe something similar would work here?

The chances of Nvidia even looking at this are non existent . The thread may be three years old, but the drivers are for an OS that's been unsupported for almost 15 years . If there is ever to be a fix, it will come from a third party patch .

Yeah, that's along the lines of what I was thinking.

My suggestion, if you want to go Nvidia under Windows 98, is to get an FX 5900 or other high end member of the FX family or its Quadro equivalent so long as it has a TMDS by Silicon Image .
Anything requiring a newer and faster GPU is probably best played under XP or higher .
