High resolution monitor and NVIDI setting.

[pnunn]

I've juts spent a small fortune on a new Dell monitor that is capable of 2560 x 1440 which it does nicely under windblows as a secondary monitor on my laptop. However, on kubuntu the maximum resolution I can get from nvidia-settings is 1920 x 1080 and I keep getting erros about MetaModes not being unique.

Any ideas how to go about upping the anti here?

Which driver are you using? Nouveau or the Nvidia proprietory one?

[pnunn]

The nvidia proprietory, (sorry more details)..

OS: Linux-
Nvidia Driver Version: 304.43
Server Version Number : 11.0

This should be the newest one. So you must wait for anybody with more knowledge about your problem.

Perhaps you can coax it along by editing xorg.conf

Have a look at these two threads, it seems to be a common problem:

Folks, thankyou so much for your input.

I've delayed in getting back here because I was waiting for a display link cable to turn up to see if that would solve the issue without needing to muck around with x configs etc and lo and behold, it did.

Monitor now operating at full grunt and is great. It's interesting the Dell don't ship the DL cable with the monitor given that it just works when the dual channel DVI cable that ships with the thing doesn't.

Thanks again for the input, very happy now.

pnunn, what is a "display link cable"? Is there a specific technical name for it?

[oshunluvr]

Sorry I didn't get to this thread sooner: Generally, resolutions somewhere in excess of 1920x1080 require a display link cable or a DUAL-DVI cable and (obviously) dual-dvi capable card. The standard a.k.a. single-link DVI cables have a gap between two nine-pin sets at the cable end and the dual-link cables have a full set of 24 pins.

[pnunn]

Display link is a proprietary version of hdmi as for as I can work out that Dell and HP use. The monitor has HDMI on it, but the dell docking station uses this display link (display port perhaps) interface.

oshuniuvr: the dvi cable supplied is, as for as I can tell dual-dvi and the dock is meant to support it according to the specs, but the nvidia drivers wouldn't give me the choice of the very high resolution until I changed the cable.

Thanks for getting back to us with your solution. It's still kind of strange that it worked in Windows but not Linux.

[pnunn]

It did sealbhach, but I had to install some dell drivels to get it to work, it didn't out of the box so to speak.
