Hey all, honestly I am not experienced enough in screens to know if the screen is amazing or not.
Coming from a 50" plasma TV, there are a wealth of differences. Obviously - size! I got the 120" EluneVision Reference Studio 4K Tab-Tensioned screen. The guys at EluneVision were awesome and had this thing at my house the day after I ordered it (with a shipping premium of course).
I set it up easily and quickly, in an hour. Mounting made perfect sense, and the operation of the unit was without issue.
I am using a Epson 5020UB Projector, and with the lights off this screen looks brilliant. I have not yet completed buildout of the room, so walls are white, there's significant light leakage from the windows, and there is a good amount of light coming in from the surrounding rooms. Watching a movie or playing a game during the day is still very clear, but I notice a lower level of vibrancy to the colors compared to at night.
In the evening (and I can only imagine even better when I actually get the walls and ceiling painted correctly) the colors pop well, and it's just like being in a theater.
There have been no issues with the screen - it was in perfect condition when it arrived (a very long box!), and although I don't retract it often (we just leave it down), there seem to be no issues when I do. The color is even and shows no weirdness (hot spotting, texturing, sheen).
All in all, I love the screen.
