No problems here playing 4k video from the P3 onto my Samsung 4k tv, i just plug the 1tb portable hardrive i have straight into the usb.3 on the tv, the hdd also has a usb.3 out
Having a usb.3 is important as it can deal much better with the 4k data for smooth playback from what i hear.
Watching in 4k is so much better than hd and cannot compare, the detail is simply amazing even if you look closeup to the screen, individual leaves on the trees can be seen at about 100ft up and the colours are so lifelike.
As long as you have a dedicated 4k display there should be no problem.
