I'm looking to upgrade my screen from what I have - a 92" Da-lite Cinemavision, to a 100" Da-lite Cimena contour. Need help with screen selection. The throw is about 11 feet, right now I'm using a JVC RS-1 but plan to upgrade to either Sony HW50ES (or it's upcoming replacement) or a JVC RX55. Room has some ambient light in daytime (only really watch football in daytime), ceiling is light colored but walls are dark. Was looking at the JKP 1.1 material - do you have to use it in a batcave, or is it OK with some ambient light? If it's not suitable, any other suggestions preferably from the Da-Lite line? I see a grain in my Cinemavision on light colored field, would like something smoother if possible.
