Installed Linux, display going offscreen

[hammad1029]

Installed linux mint today and configured it to run at the same resolution I was running my windows on via

cvt 1366 768
xrandr --newmode "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
xrandr --addmode VGA-1 "1368x768_60.00"and then manually selecting the resolution 

and then manually selecting the resolution from settings. My problems are:-
- Why does 1366 become 1368?
- When I apply this resolution, the display goes a bit offscreen both on the right side and top. I've tried multiple linux distros (ubuntu, popos, manjaro - before settling on mint) and all of them have the same issue. The software is updated to the latest. Monitor auto adjustment doesn't work since my monitor's buttons don't work but this shouldn't be the issue as everything worked perfectly on windows without any adjustment.

 

This resolution was working perfectly on windows and it's the max of the monitor as well.

I'm not sure what's causing it in your exact setup, but the issue you are experiencing where the display area goes off the edge of the screen is known as overscan. This might help you find a solution (as a google search term)

why are you manually configuring resolutions? i havent had to do this since i've last used a VGA dummy...
