Hi all. I am thinking of upgrading from a rear projection TV to a front projector. I am looking at the InFocus 4805 with a 80"x45" screen, either a De-Lite Matte or Cinema Vision. The screen will be 14' from the seats. I will be using this in the living room that has some ambient light that can be controlled to some extent with blinds. My questions are: 1. Will I have to watch TV in the dark or low light levels just to see the picture? We have recessed spot lights on dimmers. 2. Will diffused ambient light wash out the picture? 3. Can anyone recommend a good screen for this application? The missus will hate sitting in the dark all night just to watch T.V. All movie viewing would be done at night so not a problem for the main event. Any advice from those with experience would be appreciated. Thanks, Lee.
