I am using a 32" Insignia TV as a mirrored monitor via HDMI out.
Right now it works great at 1280x720, but if I choose to use 1360x768 the tv goes blank thinking there is nothing plugged in. Any ideas?
NOTE: I am dual booting Windows10 and Ubuntu 18.04. Windows10 works fine in 1360x768.

In the Displays Section.
Select "Single Display" and Select the 32" TV as Primary.
It will give you the options.
