This is my first post on the forum and given the thread topic I figured this would be the best place to ask my 3D screen related question.
I'm new to the projector game and 3D via projectors. I have recently purchased an Optoma GT720 Short Throw 3D Ready DLP Projector and have the Optoma 3D-XL on preorder to facilitate 3D via PS3, Blue Ray etc I plan on using DLP link via active shutter glasses.
I'm now actively looking for a screen for my setup and have a budget that I'm working within. In particular I'm considering going with either of these two screens:
106" EluneVision Elara II Perlux-Silver Fixed Frame Screen - 16:9 (1.4-gain, 3-ply Perlux-Silver material)
106" EluneVision High Definition Cinema Grey Fixed Frame Screen - 16:9 (1.1-gain, 3-ply Cinema Gray material for high contrast and black levels)
My setup is in the basement which has ¾ (full size) windows and ambient light is fair during the day, however most of my viewing will be in the evening anyways. I will be seated 11.5 feet away and the projector is table mounted. The projector is rated at 2500 lumens with a contrast ratio of 3000: 1, however from what I have read I can expect at least a 50% drop in brightness with the projector in 3D mode and the use of the active glasses. Given that I'm unsure of what type of gain I should be looking at given the projector is fairly bright at 2500 lumens. I have decided I would like to go with a Grey / Silver screen to bump up the contrast a bit.
I'm leaning towards the 106" EluneVision Elara II Perlux-Silver Fixed Frame Screen due to the higher gain, but have concerns on the use of a silver screen with active glasses and hot spotting.
Any feedback would be appreciated.
If you are using the 3DXL with a single DLP 3D ready projector like that, then any standard screen will work just fine, as the images for right and left are projected normally, and separated by the active glasses.
You really only need a silver based "3D compatible" screen if you are using, or planning to use, a two projector system, where the two views are separated by polarisation of the light.
