Doubt about how to increase the video quality to the maximum that the PC supports

Hi, I did some research on the internet, and I learned this command to increase the sound quality in Linux, I’m on Debian 12 wayland kde, on an intel 11th laptop with onboard only:

sudo nano /etc/pulse/daemon. conf
resample-method = src-sinc-best-quality
default-sample-format = float32le
default-sample-rate = 48000
alternate-sample-rate = 48000

But I didn’t find anything about video. Is there a command that I can use to increase video quality and sharpness, get better color, etc., that the PC supports?

In settings, I set:

full rgb range,

legacy x11 applications scaled by the system,

resolution scaling at 100%, at maximum screen resolution, 60hz

I turned off the option to allow screen flickering, and set latency and smoothness balance,

to fonts, I set the subpixel to none and the hinting to full,
and in the desktop effects options, I reduced the blur and noise to the minimum possible, in addition to enabling the contrast enhancement mode.

Thanks in advance :smile:

default-sample-rate = 384000
alternate-sample-rate = 384000
