Windows 7: Cant get full 2560 resolution from Nvidia Quadro NVS 295

Cant get full 2560 resolution from Nvidia Quadro NVS 295

After fitting a Nvidia NVS 295 card into my new Advent computer (Foxconn mobo, i5, 8GB RAM) my DELL ULTRASHARP U2711 will not display at its maximum 2560 x1400 res. I can only get 1920. In fact 1920 is the highest selectable in the Nvidia control panel. I let the Nvidia installer set up everything without removing the onboard AVG driver first - I assume it did this automatically? I am using the DVI cable that came with the Dell. What am I doing wrong? I have used the latest Windows7 64bit driver download from Nvidia website.

Hi,
http://www.nvidia.com/docs/IO/68245/...INAL_LoRes.pdf

States here to use 2560 x 1400 you need to use display port.
DisplayPort to DVI-D (Single Link)

>
industry standard cables can be used to
drive digital displays at resolutions up to
1920 x 1200 @ 60Hz
Your monitor has a display port connector. To utilise full resolution you need that.

Yes, I am using a display port to DVI-D adaptor. My suspicion is now that the NVS 295 card comes in 2 different resolutions - 2560 and 1900. I seem to have the lower one. The packaging and website information on this product is very ambiguous.

No you need a display port to display port cable, it stated that in the pdf, DVI maxes out at 1920 x 1200 @ 60Hz
DISPLAY RESOLUTION SUPPORT
Dual DisplayPort outputs drive >>DisplayPort enabled digital displays at resolutions up to 2560 x 1600 @ 60Hz
DisplayPort to DVI-D (Single Link) >>industry standard cables can be used to drive digital displays at resolutions up to 1920 x 1200 @ 60Hz
DisplayPort to VGA and DisplayPort to >>DVI-D (Dual Link) industry standard dongles will be tested for compatibility by NVIDIA as they become available


Crystal clear it is read the pdf I posted above and buy the display port to display port cable and you will get the higher resolution.

I am a home brewer of real ales - I have 2 barrels always on tap! Now stocking up with Xmas 'winter warmers' - 5.7%. Clovelly was in the news last week - heavy rains had caused the river at the top of the hill to burst its banks and flow down the main street all the way down to the harbour - turning the sea red. Might be on youtube.

YES!

Thanks Indianatone!! Got the right cable today and I can now get the full 2560 x1600 resolution - WOW! what a difference it makes - photos look wonderful but text is incredible small, though but I only do photo-editing so that's OK.

Glad you got it working and posted back as this will help someone else. That would be my problem with such a high resolution, I could not read the text but for editing photos, wonderful. Enjoy your monitor and have a pint!

(color, font size, and bolding changed by me)

Dual Link DVI was used for high res (2560 X 1600) monitors before Display Port became available. (Dual link suggests 2 cables, but it's really one.) You might have gotten 2560 X 1440 if you had a DP to Dual Link adapter. Apparently, you did not.

I write this to correct the impression some may have that you can't get the high-res graphics with DVI. You can, but a Dual Link capable card (and cable) are required.

DisplayPort is best for you, though: no adapters.
