Just got my new DVI flat panel monitor today, the BenQ FP231W. Incredible monitor. Huge and bright, with no dead pixels. Best of all it was very reasonably priced.:)

Anyhow, I've had some issues in getting it to work correctly. Using the DVI connection on the normal (top connector) would work, but it wouldn't allow more than 1600x1200 resolution (stretched) regardless of monitor driver or control panel configuration. I even tried to enter the resolution manually, but I got an out of range message. Things generally looked not so good on the screen in terms of clarity and sharpness.

Switched to the bottom DVI connector, and there is a large improvement in capability and picture quality. I can run at full resolution with a very clear picture.

Anybody have any idea why this would be?? Did NVidia use a different driver chip for the top DVI output?? I was thinking of getting another of these monitors in the future, but I won't if this is the type of thing I can expect from that connector.

Disappointing to say the least...especially from a video card of this caliber.:(

i have the same card with a dell 20 inch plasma and no matter which dvi i use i have no problems. have you tried different drivers and refresh rates?

Refresh rates were the same for both connectors...60Hz.

I'm using the Forceware 66.81 drivers...I can't see why drivers would affect one connector and not the other.

I'll keep fiddling with it...maybe it's a Windows screwup somewhere...:rolleyes:

Im a say it could be the monitor, 1 that i had, messed up big time on my Fx 5950 ended up that the card was to powerful due to nvidia changing its chips, try contacting the manufactor of the monitor and ask them are there any known issues with your model and the card you have, incase others are getting the same problem.

The same thing happend to me with an EVGA 6800U and two brand spankin' new Dell 2001FP's. DVI would not function correctly at 1600x1200, it would cut in and out, then blurr, all kinds of weird results. Ended being a good oppurtunity to return the 6800U for an XT-PE :). I remember reading about other similar experiences specifically dealing with DVI issues.

Turned out to be a driver issue. Went back to the 61.77's from the 66.81's and everything works fine.

Strange though...
