Portrait output over HDMI from iPhone

I want to mount a TV or other external monitor in a portrait orientation and mirror an iPhone to this screen via the lightning to HDMI output adapter. However, when I do this the video is sideways because the monitor doesn’t have any direct control of the video feed.


is there a way to rotate the output over HDMI by 90 degrees so that the portrait video takes up the full portrait-oriented monitor it’s connected to?

Is your external monitor also oriented in a portrait fashion?


I’m trying to make better use of the monitor. By turning the monitor 90 degrees, in theory I should not have massive letterboxing on the left and right edges of the screen and the picture could be larger.
