Help. The TV I'm trying to use as a monitor has overscan issues, it overscans both 1080p and 720p resolutions. For my use, I'd rather have borders compared to a cut off screen. I'm trying to get Linux Mint to output video to an external monitor like this.

In mirror mode: enter image description here AND still work as the primary display if the laptop is closed

Windows 10 does the above ^ fine. But I can't get Linux Mint to preform the same way.

I tried entering in this

xrandr --output eDP1 --primary --auto --output HDMI1 --auto --same-as eDP1

but all I got was this: enter image description here

So my TV still overscans the top and side portion.

How do I get it centered? And have borders so apps and programs can't go beyond the 1366x768 resolution?

I posted the same plea for help, with perhaps just a few more details, on the Linux help forums


More info:

xrandr --output eDP1 --mode 1366x768 --output HDMI1 --mode 1920x1080 --same-as eDP1

Then this:

xrandr --output HDMI1 --pos -277x-156

seems to do EXACTLY what I want. EXCEPT only with my laptop lid left open. Closing the lid seems to reset everything :( Even lifting the laptop lid again, it doesn't remember the previous setting. I have to re-enter the commands in terminal everytime sigh

Now if only I could figure out how to keep it working the way I want it no matter if I close my laptop or not. And no matter how many times I open and close it.
