4k monitor help needed.
HI, I have an unusual problem, I recently got a 2008 Mac Pro 3.1, I installed ssd drives, lots of ram, etc, it's a plane this thing, but I also changed the graphics card, an ATI 5770 and it has Display port as well as 2 DVI ports, I been looking in my area for a 2560x resolution monitor and I can't find one, but I found a Samsung 4k monitor, but since here is almost $1000 US I don't want to make the mistake of buying this and lots of money for not supporting at least the 2560x as resolution. Does anybody know if this 4k monitor will support the max resolution of my card or will it only be 1080? II'm not a gamer, only edit pics and video. Anyone know if it will help? Thanks in advance.
