What is a good ceiling mount?
Also what about a screen?
Will a 120 work or would a 135 be better?
White or grey in color?
The room will mainly be used at night to watch movies and play some video box games.
I ready to get this thing going!!!!
Ceiling mount for that high of a ceiling? Hopefully someone with experience with a high ceiling mount will chime in. Obviously it heavily depends on how far the top of your screen is down from the ceiling.
Screen size, for that size of room I would go with 135" or larger. Big variable here is front row distance from the screen. Also, your susceptibility to RBE will affect this decision as well. While I can personally get away with a 1x screen size distance and deal with minimal RBE; I still think the general 1.5x to 2x screen size distance is more optimal both for reducing RBE and eye fatigue. Though I like having my front row a little closer than I like, so it's a different experience while gaming. But then generally sit in the 2nd row for movies. Again, a lot of personal preference going on here.
If you haven't already, I highly recommend playing with the HD20 on a table/stand and your wall to see what size you prefer and how far you want the front row from that size image. Then test for RBE and general eye fatigue with that test setup. Maybe even watch a full length movie to see what you think.
White vs Grey. Another big topic. I have tested both in my environment and prefer white with my bulb on low. Testing both is a pain and you have to deal with returns, etc. If you have a dark colored room and watch in darkness or very low light; then I would stick with white. Another factor for me was cost. I was testing my DIY white 125" screen against a cheap 120" grey screen. And preferred the low cost white screen material.
While there is a lot of opinion and choosing yourself by testing in your own environment is best; if you want to skip the testing, then I think a white 135" screen with a 1.5x viewing distance, trying to keep the center of your screen only slightly higher than your eye level while sitting down and not reclined, is a great default answer.
But you could test and find out you prefer a 120" grey screen at a 2.0x viewing distance. lol.
