My air tv player (android tv box) did 4k 60hz natively. In windows and linux not so much. Windows only required me to switch it to 60 hz in dislay settings. Linux was some work. 1st problem was that linux sees this 50 inch tv as a 32 inch tv. That's not a problem i could fix but it pointed to the real problem, the edid.bin file for the device is not working as intended. Luckily, i have manjaro linux and the support forums were amazing. Someone found a edid .bin file for the u50. Then after we read the .bin file (read-edid and edid-decode) we could see what modes it was capable of and through the wiki for arch linux we were able to force the mode setting then we set it up to autostart in that mode (3840x2160 60 hz) through lightdm.
So why did i give it 5 stars when i had all that trouble? Because sometimes that how linux is. Sometimes linux takes a little more work but it pays off in the end. And also because you wont find a tv this nice for this price just anywhere. The sound is abou 3-4 stars but the picture quality and the features are wonderful and oh, it 50 inches and oh, it does 4k at 60 hz over hdm 2.0.
So if you need a tv for linux, choose this one, we did all the hardest work for you. If you need help with your linux, consider using manjaro for your needs. In the help forums, go to the newbie corner and search for the thread titled xrandr vs monitor specs. Everything is there. You should be able to follow it and get it going. And be sure to check out their great linux distro !
PS. Here's my machine's specs:
