Room is rectangular - 13.5 feet wide and 23 feet deep. The first 'challenge' with the room is that the back 7 feet of the left hand (facing where the screen will go) wall is open to the rest of the house. The stairs and balcony are here, so there is no practical way to close it off and control the light during the day. Walls are are dark(ish) cream color, ceiling is white, and for now I don't think that will be changed. The second challenge is that where the screen will go is a large window facing west. This (along with 95+% of the whole front wall) is currently covered with black colored black out curtains that block all but very incidental light around the edges as-is. Bottom line is that during the day there will be incidental light coming in from the back of the room that I will have no control over. Main challenge with the window is that I will need to hang the screen from the ceiling.
Screen will be used for viewing TV/Movies, and for gaming (XBox/PS3).
Thinking about a 105-110" screen, as this will give my current speakers the room they need to perform optimally. A screen that pulls down (either manual or motorized) would be best so that it could be raised out of the way for access to the window for cleaning/etc.
The final challenge is that the budget realistically needs to stay below $1500 (including taxes if any).
Looking for advice on what screens would be the best fit for my situation.
