Bought this monitor and returned it the same day because although I have an Nvidia GTX 560 video card, it was not powerful enough to scale resolution up to 4k HD.
With the video card I have I was unable to go higher than 1080p !! So, before you buy this monitor,
please sure you have the right video card with HDMI 2.0 and/or a Display port.
