Tiling display support

[George Shuklin]

Hello.

I continue to choose hardware carefully, and the next issue (I found a 
lot on it) is support for tiling displays. They uses multiple streams 
inside DisplayPort to achieve high resolution with high frame rate. It's 
called MST (vs classic single SST), and I found few people complaining 
about issues with it. All those complains are relatively old (2+ years).

Does someone run desktop with 4k screen and high frame rate (150 fps+)? 
What monitor and gpu are you using? Are you having any issues?
