From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux 4K desktop/media server (lemmy.world)

I have a TV which says it supports 4K 144Hz and right now I run an old laptop as a media server/desktop to it, which can only handle 1080p. I wish to switch to some NUC/mini-pc that run a linux desktop in 4K and run media flawlessly on it.

There are two things that I get confused about trying to find something that suits my wishes:

How do I properly find out if the hardware can handle this? Like a rpi5 can handle 4K video playback with like librelec, but a 4K desktop distribution is laggy and slow. Is a CPU only enough, or do I need dedicated GPU? Should I be looking at the Ultra Core series from intel, does it have good linux support?
Are my wishes on hdmi 2.1 level troughput? Which may not work on linux? Reading about hdmi 2.1, then it says that the hdmi forum forbids open source support for hdmi 2.1, does that mean there are binary blobs for linux that will work?

Is there anything else I'm missing? If you run a linux media server, what hardware and dist are you running?

You find out if the hardware can handle it by looking up its video decoding capabilities on Wikipedia and checking that it’s capable of the resolution and codec you want. If you’re buying new hardware then a chip from Intel or amd that support the resolution and codec you expect will do the job. It doesn’t need to be the latest and greatest thing.

If you can’t be content with 4k60 over hdmi then you either need to use proprietary drivers or a different cable. Your tv very well may have a displayport slot and that’ll sidestep the problem. I don’t have problems with proprietary drivers but you may.
