My conference room with control lighting in the front of screen. The room dimension is 24' x 24' with a 133" diagonal Da-Lite / Da-Mat finish tensioned pretty much dead center with white tiles and off white walls. I am looking at either EH200ST or EH415ST. The room will be used in a mixture of video/presentations. I need a throw below 5' and less is better. When I use the projection calculator on the EH200ST it goes into the red for ambient light (worst on the 415) and the brightness in ft is 57 on presentation and 29 on video. Would these projectors be acceptable in room like this producing a high quality image without be washed out? I have tried an NEC NP-M353WS and you can see black grids (like you are looking through a screen door) and not very sharp at 6-10 feet from the screen. I am open to other projectors options and higher in pricing if needed.
