When the FREESYNC AMD RX490 gpu becomes available in 6-8 weeks, smooth 4k/75 should become reality

Good affordable 4k

This monitor should support 4k at 60 HZ with any of the of ports it has (2 HDMI, 1 Displayport)

it!I did find one cheaper 4k

I bought this specifically for the new Xbox one S which supports 4k.

While it claims to support 4k

Best 4k Monitor ever!!

(also I should mention that regardless of it's horrible 3 star rating on Apples website, the 5K display works perfectly fine with my Mac Pro and 2016 MacBook Pro 15 inch

If you are looking for a 4K gaming monitor that works with the PS4 Pro, I can confirm that this one does work.
