I will be getting a Sanyo PLV70 / Boxlight SD20 in the next month or two. But I had some questions about how to place my screen in my room. I have a completely unobstructed short wall in my 18'x29' theater room to place my screen. Don't anyone get envious of a room this large, I only have a 7'6" ceiling due to the way the drop ceiling was installed prior to my purchasing the house. Because of various fixtures and such, I cannot raise the ceiling. Am I going to have problems installing a 106" or 120" diagonal 16x9 screen in this kind of a room? My viewing position is from a couple of leather sofas that sit kind of low to the ground. Fully seated I would say my keester isn't more than 18" off the ground. Thanks for the assistance / advice.
