The big advantage 4K screens have over HD is almost eliminating the
dirty screen & the LCD screen door (mesh) effect.
The 4K screen has the potential to be a better display with HD material.
An HD screen at TV size was never really okay as a computer monitor.
A 4K OLED with DP would be stunning.

The video cards are way behind probably because the hdmi spec delays.
Only the GTX950 & GTX960 decode HEVC 4K & have hdmi2.0 (4K 60p 4:4:4).
The GTX750 (& others?) full h/w decode H264 4K hdmi1.4 only or DP
The GTX650 does partial shader decode H264 4K hdmi1.4 only or DP

Sadly no TVs have display-port.
IMO A computer monitor needs 4:4:4 & 60p.
