I'm in the market to make my first projector purchase with a budget of around £2000 and am currently leaning towards the Infocus Screenplay 5700. My plan is to ceiling mount it at the back of a 6x4 meter room onto a +- 200 inch screen. The projector needs to be HD friendly, which the 5700 is. My question really is, what would you, the experts, pick out? Is this a good choice for a first purchase, and given a projection distance of around 6 meters, will a 200 inch screen be about right? Seating position is from about the middle toward the front of the room, if that makes sense, so viewing distance will be around the 3 meter mark from the screen. In addition, one side of the room is flanked entirely by glass doors. Am I throwing the balance of the sound field out if one side becomes heavily curtained, whilst the other side has a large canvass painting on the front half of the wall?
