I just got a dell u2711 which can handle a max of 2560 * 1440 resolution. My graphic card is Geforce 7600GT which supports dual DVI and up to 2560 * 1600 pixels. When I plugged my monitor, the max resolution I can have is 1680 * something pixel.
Anyway I've done some google search and people said basically I need:
1.) Supporting graphic card (check)
2.) Use dual link DVI cable (check)
3.) install the current driver, I did this using the driver update (check)
I'm using ubuntu 12.04 LTS and I updated all my software.
Is there anything else I should do to get the max resolution to be 2560 * 1440. Do I need to edit xorg.conf and add 2560 * 1440 resolution manually?
Would that make the performance go slower? or is it supported natively?
