How to use xrandr to fix overscan on a old samsung TV?

Question

I just installed Ubuntu and my monitor is having a issue with overscan in the Y axis, more or less, 150 pixels. I tried using my TV control but i had no success. Using Windows works fine, so i guess it should be possible in Linux.

Please investigate further the menus on your TV set. You should be able to do "1:1 pixel mapping". — FedKad, Jun 30 '21 at 10:36

you could try this

xrandr --output HDMI-1 --set underscan on

If this does not work kindly post the output of xrandr

It works, but i get black bars in my screen. Left, right and bottom. Therefore, the resolution gets a bit smaller. – Fear of the dark Jun 30 '21 at 05:35

okay you can try `xrandr --output HDMI-1 --set "scaling mode" "Full aspect" ` or `xrandr --output HDMI-1 --auto` or `xrandr --output HDMI-1 --set underscan on --auto` – anubhav sharma Jul 02 '21 at 04:13
