There is actually some 4K content on Youtube. I tried watching it on my computer and got the blue screen of death.
It rebooted okay, but I’m not going to try that gain.
Yes, and that’s why I upgraded to the ROKU Ultra, a 4K player, so that I can watch YouTube 4K videos, and 4K movies through VUDU.
It’s with a 4K video like this that I appreciate fully a 4K TV...

BTY, for my 720P Computer monitor, I just set the YouTube function to “Auto”, and most videos will play at the highest rate up to 720P, even if the video has 1080P or 4K or higher available.
