Summary: our room is longer than most>25 ft, but the projector does the job. 3D is awesome and works well. You can leave the lights on and still see. We use just the wall painted with very flat white paint. The wall is textured, but you can't see it. much cheaper than buying a fancy screen or using the expensive screen paint. As with any projector, you have to be patient with connections and read the instructions.
Summary: This is the second Denon I've bought. This was for another room. Sound quality can be a subjective thing but to my ears this is an excellent unit. I do like the room tuning feature with a microphone on a long wire you configure the unit to suit the listening environment. I never realized the benefits a dedicated AVR unit can bring to the media experience until I bought one, or in this case, two.
