Outputting a computer screen via hdmi can be problematic. If a 5m cable is bought for 1k (for those who are not in the subject, like me, a good hdmi cable is an important component of a calm gameplay). In my case, the screen started flickering (turning on and off for a second), not often, but it's not pleasant. The video of my computer is 1070, and in theory there should be no problems with 4k, so I sin on the cable. But for watching 4k movies, from the hard drive, that's it. On KinoPoisk, unfortunately, there are only a few of them.
