E.g., with eyefinity, you may have a large surface with 3 or 4 monitors looking into it that the 3D engine is rendering to, but each monitor is only scanning out a small portion of the total surface.

Originally posted by agd5f View PostAs I said before, DCE5 cards (Northern Islands) only support 4k monitors over DisplayPort (DP). For 4k over HDMI, you need to a DCE6 or newer card (Southern Islands).
BTW could an amd employee wear a ski boot and kick the guy who came up with all the numbering, names, etc in the throat. I would truly appreciate it.
