I am also interested in what guillerodriguezv has requested.
I want to play PC games that are NOT ON STEAM on my PiMax 4K.
From my experience, I can only get them to work in VIDEO MODE and not in PIMAX MODE.
Just need to track movements in four axis left right up down and move the mouse accordingly.
Think about it… Playing DOOM or any old school game on your PC (NOT ON STEAM) with PiMax as secondary monitor and when you turn left or right or up or down you are looking around the scene. It just needs to get the direction of head movement and tie that to the mouse.
Does anyone know how to achieve this?
