Resize an Image to Fit the Screen of an HDMI Display

So I have this curved 1920x1080 23.6'' monitor and even though I run it at this resolution I have some empty blank spaces at the edges of my monitor.
About 5 mm vertically and 2 mm at the top.

Back in my windows days I would use this guide https://www.amd.com/en/support/kb/faq/dh-022 . But since AMD doesn't have a Radeon Software Control for Linux I can't do that.

I tried to fix it using xrandr but I am too noob to figure it out.

Can anyone help me?

Thanks for your time.

With xorg you can probably set some properties with xrandr:

xrandr --output HDMI-A-0 --set underscan on &
xrandr --output HDMI-A-0 --set "underscan hborder" 32 --set "underscan vborder" 18

I did that and the screen size shrank even more. But thanks to that I realized that it was in already in my max area. Turns out my monitor is badly designed and that was just empty glass with no pixels underneath. Sorry for bothering you people
