I am confused . I was advised by a HT specialist to get the motorized SI Reference solar screen (100") which is 1.3 gain. When I use the SI screen tool it suggests the lunar, .8 gain. I spoke to the company and they also felt the gray would be better suited. I used a screen selector tool from another company and it recommended a 1.3 gain screen.Then, I read a review by one of the AV magazines and the writter highly recommended the solar for most situations and did not recommend the lunar. Here is my situation. My room is 25'x12'. I have several windows (will be installing shades to control the light). The vaulted ceiling is white and the walls are tan. The carpet is light tan. I plan to get the Epson 5020. Mostly for movie watching at night plus sports. I haven't bought anything yet so I am open to suggestions and a little clarity.
