In case anyone is looking for a UHD/4K monitor for a mac that won't break the bank, check out the new Samsung U28D590D(~$600). Â It is a true 60Hz 3840x2160 display. Â I am using it with a GTX680 card in a MP tower (10.9.2) without a problem. Â You card must have displayport to get the 60hz refresh rate. Â Makes a great AE monitor with LOTS of screen space, although your sight has to be pretty good to see the text at that resolution. :)
Anyway, I thought I would pass this along if anyone is in the market for such a screen but didn't want to pay the $3k most are going for.
