Adjust sharpness / contrast?

FXAA is a gaming Anti Aliasing filter, that saved performance with the trade off
in picture quality, while MSAA demands more performance and gives better and sharper image.

Besides gaming i never saw this filters has a impact for other environments.

The monitor is the LG Ultrgear 32GR93U, Res. i 1920x1080. have trouble seeing thew tiny screens at 4k. Videos do look hazy sometimes. like this one here is the shot

There is a big Problem

LG Ultrgear 32GR93U = 3840x2160


Please post the outputs

ls -l /etc/X11/mhwd.d
ls -l /etc/X11/
ls -l /etc/X11/xorg.conf.d
cat /etc/X11/mhwd.d/nvidia.conf 
xrandr --listmonitors
xrandr --props

in linux (which also makes sense) you always take the native resolution (in your case 3840x2160) and scale the surface. Then everything stays sharp.
If you only display 1920 on your 32`` it must automatically become blurred.
That’s why it’s so problematic with old games that can only display 640x480. But you can’t recognize anything but blocks.

Ok, hmmmm. I don’t think X will let KDE scale enough to see good enough. Watland still has issues though right? Things will be tiny.

test with 175%

I am just below native res. at 200$ scale. Man I miss my young eyes, 25ish years ago, I was on the Quake leader boards, played on a 16.8k (yes not Megs) connection with out using a crosshair. I could read fine print without glasses.

Tell me about it. I feel the same way

I know this sounds odd, but things look like they are a little underwater with a tiny bit of silt floating in it, not sure if it is a moniter thing, my eyes or a setting. Like you know how a tv with glass looks better then a movie theater screen? The image is great otherwise.

Maybe post a photo if you have a camera capable of close-ups? (Macro). If it’s a phone camera, horizontally please! That way it’ll be clearer for us to see what you mean (pun intended).

You must disable SMART ENERGY SAVING in your Monitor !

I was thinking of my phone, I was wondering if I could turn the filters off? The images always look clarer on my phone. Shot

Last 2 not sure what 2 do. The ae confused me.

Moniter is LG Ultragear 32GR93U

everything looks good

Ok, thanks.

The Contrast slider in colors seems to do nothing.


@Edward78 Please post the decoded EDID of your screen…

pamac install base-devel
pamac build edid-decode-git
find -L /sys/class/drm/ -maxdepth 2 -type f -iname "*edid" -exec sh -c 'echo "{}"' \; -exec edid-decode "{}" 2>/dev/null \;

The EDID is a binary blob inside your screen and Linux heavenly rely on it, since it tells which resolutions the screen is capable of.

Probably try another connection. Display-Port should be preferred on Linux.
