Image 1 is with the curtains open. The curtain you see is at the back of the screen. Points to note, projector can't project black light, so it'll only get as dark as your screen is
Image 2 is with the curtains drawn and the 4 front top can lights turned on. For brighter pictures it's fine.
Image 3 is the seating area cans (4 of them) turned on. I could lower the brightness color and contrast to get a better image. This is generally how I generally watch sports.
Image 4 is the trailer of Dark Knight in the tunnel. With the curtains open noting is visible, no matter what I do (side ALR isn't the best!!!)
Image 5 is the front top cans switched on. While certain details have returned, it's still unwatchable.
Image 6 is the rear 4 cans on. Image and movie is watchable but i wouldn't prefer it.
Hope it helps. Though to begin with, since I'm in a rental all walls are not the colors that I'd want, but what I have.
Can this screen do better? Yes.
Would I rebuy it now that I know what it's capable of? Yes
I had a locally made grey screen installed before this and this is so much better at the contrast. If I put a white paper on even a white part of the image, it completely disappears.
I think the videos of black diamond I've seen on YouTube are a little excessive and probably using laser projector, but there is one from that home theater dude, which puts a home projector on a black diamond. I think that'll be a good point to start.
