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.

In my Linux mint I downgraded to playing only 1080p because 4k is very laggy and filled with artifacts.
I have a mini optiplex 7070 with 32GB of ram, Intel processor (not a powerful one).but in windows 11 I could play 4k content with no issue.
Mint ships an old kernel by default. But there's a GUI that lets you install a newer one.
This would most likely fix your issue.
Or do you have an nVidia graphics card and didn't install the proprietary driver?
No graphic (its integrated with the CPU). Ill have a look
Edit: realized that i didnt specify videos. I want to play 4k videos, not gaming
In that case, you're missing codecs.
For video players, they'd be called gstreamer-plugin, and for Firefox they may be missing in the distro repo's version if it focusses on open source software.
The version from Flathub has them.
My other thought is screen tearing and similar. I think Mint still ships with X rather than Wayland and screen tearing is a pretty infamous limitation with Xserver
See if you have qsv decoding support enabled. The Intel CPUs in those little mini pcs usually have a video card that will do the heavy lifting using a system called quick sync video but if you’re isn’t set up to decode in hardware then it’s gonna have to do all the work in software and that’s slow.
You could try one of the "gaming" focused distros like Cachy or Bazzite. They do their own tweaks to squeeze more performance out of you hardware. Sadly, many game won't reach the performance level of Windows, but you can get pretty close, like 85-90% close (depends highly on the game in question, no guarantees).
Big upsy moment. Playing videos. I just want to watch legal movies
That is even stranger. My RX6600 has zero issues with 4k 10bit content. Do you watch via browser or ripped dvds?
Using vlc to play super legal movies
Oh, ok. That makes some sence. I had a similar issue with Fedora 41 as they didn't update to a newer version of FFMPEG that fixed some conflicts/issues. I had to download a different video player that shipped with it's own ffmpeg packaged. Can't remember the name, but try seeing what's in the software store. You might be affected by a similar problem.
