I have machine running Loki that has both a VGA port and a display port. I'm using a 23 inch HDTV as my monitor and my resolution works fine when using the VGA port: 1920x1080.

However, when I try to use HDMI, the resolution is all messed up. Since my monitor only has HDMI and not display ports, I'm using one of these cables. The resolution still shows 1920x1080, but the top and bottom and a little of the sides are chopped off. It seems as though a simple auto adjustment from my monitor would fix this issue, but I am unable to auto adjust when using HDMI.

Has anyone else had these issues when using HDMI?

Does the display have overscan settings? Some TVs still crop the edges of the frame off, due to a largely obsolete technology.

Here is a Ubuntu discussion which may be of assistance: https://askubuntu.com/questions/4358/how-do-i-fix-overscan-on-my-hdmi-hdtv

You might be able to fix it on the TV, but basically either you get the TV to stop cropping the frame, or you get the computer to send a larger frame, just so the TV can crop it!!!

Yes, this is still a thing in 2017!!!
