Ok. Thanks and sorry for my english... I have actually a optoma HD 25. I use it with the himedia Q10 pro, to watch movies in my living room. A Big room, with white walls... Not really good for light, but it is a true pleasure nevertheless for us.
To watch movies, in a non specific cinéma room, which for you is recomended between this 2 models? (Benq 2700 and optoma uhd52alv)
I have a base of 125inch, and the distance between vp and screen is 450 inch.
Thanks for your advoise.
