On the Macbook pro with GT 330 M graphics (circa 2010?), running Ubuntu and Linux Mint - Mint could easily detect a TV which was capable of 1366x768 display connected via a VGA adapter to the mini-displayport, and could start a secondary display on it. But it could not force 1080p out of the box. Mirroring the display caused the resolution to drop to 1024x768.
Ubuntu 18.04 - the mirroring option was not visible on the Display applet. But as per this page, was able to hit Command+p and mirror. Unfortunately, the mirroring did not automatically choose a supported resolution, so display was garbled on built-in display.
On MacOS, interestingly enough, neither the TV nor an older VGA monitor could be displayed - enabling the secondary display caused the OS to crash (or at least blank the display completely).
A detailed post on how to set desired modes:
