Zarak,

No, one entire wall of our living room is basically all windows facing the backyard, without any window treatments (yet). So, the room is VERY brightly lit during daytime. The projector is next to useless during the day. We kept a 32" tube TV on the built-in shelf on the front wall, and installed a big pulldown screen in front of the shelf. I just uploaded a series of photos of our "living-room HT" in the AVSforum. Please see this thread.
