I will have a room in my new house with just 1 window which I can blackout, but the doorway into the room (acutally a 4 step stairway down from the kitchen) has no door and there is no good way to add one. Will any projector provide a good picture under these conditions. I've been through the model home during the day, and even without blackout shades on the window, its pretty dim in there with the lights off, but I cannot control the amount of light that comes in from the kitchen. I wish there was a way to measure the amount of light in a room. Any suggestions on what might work?
