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

aq flag

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".

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
