I just picked up one of those fancy Dell U2711 27" screens that has a maximum resolution of 2560x1440. While I await delivery, I need to upgrade my graphics card to drive this baby as my current one won't do the trick.

I am considering an EVGA with an nVidia GTS450 chip and dual DVI-I ports. It can go up to 2560x1600 in DVI-D mode with the corresponding dual link cable.

Should I expect any driver issues with this setup and the nVidia binary drivers? I have googled quite a bit and most people I found claiming problems with these resolutions are using notebooks (so either VGA or HDMI, that I don't think should work).

Edit: Is it possible alhough all the components are good up to 2560x1600, that they won't allow me to set 2560x1440? I've had this happen with some widescreen LCDs in the past where a video card would go up to a higher resolution, but the exact mode needed was not an option (resolutions such 1152x... come to mind).

Conclusion: Indeed, everything worked out of the box with the nVidia binary drivers in Meerkat. Just for future reference, I ended up using a GTX460 card with a dual-link DVI-D cable. Thanks!

    It depends on the max. speed of the DAC in your video card and that of the ADC in your monitor what resolution is supported over a VGA cable (and of course the quality of the shielding in the VGA cable is relevant too). CRT monitors that support at least 2560×1920 and maybe more over VGA do exist (and have existed for quite some time).

Quoting this blog post:

I'm using the Displayport connector [...] and have no problems running at the full 2560x1440 resolution. Further, I had zero problems using the Nvidia driver that comes with Ubuntu. It detected the display, set the maximum resolution and refresh rate, and worked right out of the box.

I can only assume that it will work fine when using a dual link cable.

BTW, the monitor's manual explicitly states that the HDMI resolution is limited to 1080p, so ignore all the threads where people complain about not getting 2560x1440 via HDMI. :)

Up to 2560x1600 is supported by both the DVI dual-link and nvidia driver.

It should "just work". Sounds like an awesome display.

I'm running dual display, 2048x1152 + 1280x1024 without trouble.

With a suitable graphics card and dual link hookup, I think you'll be fine.
