Re: Video card that will support 2560x1440 under Ubuntu
It'll support resolutions up to 2560x1600 if it have Dual-Link DVI-I.
AFAIK all currently produced desktop cards have it and if they have HDMI it also supports >1920x1080.
OS: Gentoo Linux, ~amd64. VideoCard: GeForce GTX 470. ASUS P8P67 Deluxe, 2x4GB DDR3-1600 CL9, Core i7 2600k.
