We are trying to replace an older Optima projector, but we'd like to upgrade to something that can be used to show higher resolution, has more lumens, a longer lamp life, but will still work with our audio equipment. We bought something and had to return it, because we couldn't get the display small enough in our room.
The wall area we have to use is 43" high, 70" wide, so about an 80" diagonal. The projector itself is set at 12" 7" (152") away. To get it any closer, we'd have to have it hanging above our heads. And the room is designed with the ceiling angling down, so ceiling mount is out.
The audio equipment has ordinary analog input. We have a blu-ray player (not yet used) with HDMI and digital audio output. Ideally, the projector would have plugs for RCA phono-jacks. In other words, we have a nice library with a wall, nice old speakers, and would like to upgrade so we can watch blu-ray without replacing everything and perhaps also having to move to a completely different space.
