I have it wired for 7.2 surround, and have smurf pipe conduit and power to the front wall and to the ceiling in middle of the room, so I can do pretty much anything I want. The room has quite a few windows and is pretty bright during the day.
Options are:
1) 98" - 100" QLED or QNED display mounted to the front wall.
2) UST projector with ALR screen on the front wall, probably 120".
3) Traditional ceiling-mounted projector, again probably with a 120" screen.
