I chose this canvas for my projector.
One can attach the screen either on the ceiling or on the wall. I have attached to the ceiling (in a bar), where she also holds excellent.
The image of my Sanyo projector looks very good on the canvas, the colors, everything was great extent.
A star deduction is available for the waves having the screen with me. Whether they extends all or only a part, the waves are always there.
I can When I play a movie called the waves as well as not. However, when logos are projected on the screen, so they are not just run up in waveform. But as I said a star deduction, otherwise I find the screen just fine, especially when you take into account also the price-performance ratio.
