GTX 590 Does it support 4K video?

Wouldn't you also need multiple connectors to use a single 4K display? Or can you do it through a single DP1.2 connection? I can't remember.

I think it can be done over single DP 1.2 there was talk of being able to run 4x 1920x1200 monitors over one DP 1.2 connection when it was released. 4k is essentially the same number of pixels and blanking information should be reduced for 1 panel vs. 4 panels.

But you forget that monitors of the specs in question would undoubtedly be 10 bit panels as opposed to the 1200p 8 bit ones.
However, wiki does claim DP 1.2 to suppport 2560 x 1600 x 30bit @ 120Hz (think 3D). Sure would like a product like that. I don't know about the blanking but from the numbers on wiki, it does appear as if 4096 x 2160 x30bit @60Hz would be well within the 21.6Gbps quoted for DP 1.2. Even 12 bit appears to be barely possible with CVT-R.

A 4K display would be awesome! No more of this 1920x1080 crap.

Imagine how much text you could fit on that screen, if you are a programmer. Heaven!

The official word from AMD is that DP1.2 and "Fast HDMI" both support 4k displays. Bit depth and framerate are not mentioned, though I suspect HDMI would be limited to 24fps.

The main point is to have a smaller distance between pixels, which would necessitate a higher dpi font (because there would be more ppi -- pixels per inch)

100 dpi fonts on a 24" 4k screen would defeat the purpose of the display. The whole idea is to increase actual resolution, not just get more pixels at the same density like they do now (17" to 30" are all within about 10% ppi resolution)
