Windows 11
for better 4K support
Err no? Windows 11 has better HDR support, specifically auto-HDR, whereas Windows 10 you need to manually toggle it. Also the HDR algorithm is better on Windows 11, as it has better tone mapping support, whereas on Windows 10 you had to manually adjust it.
If you are watching 4K UHDs with HDR, this makes it a bit easier.
For 4k resolution, windows 10 still has slightly better performance.
