    I am purchasing a screen that is 178:1. I am noticing that most of my DVDs are 235:1. What is projected on the rest of the screen? Is it black bars like watching a widescreen movie on a 4:3 T.V. or is it just blank canvas? DO I have to reset the lens on the projector every time I put a DVD in with a new aspect ration or does the projector automatically project the image onto the screen in the new format? I am going to be using a Benq 8700. Any help would be greatly appreciated.

    Greetings

    Use the ana mode ... and yes you get bars ... as 2.35 not = to 1.78 ... and never will be.

    bars are just thinner than on a 4:3 set.

    As long as the DVD player is set up right ... leave the 8700 at anamorphic ... unless you watch 4:3 material ... then use letterbox or 4:3 modes.

    Do not use thru and wide.


    Regards

    Leaving the projector and lens the same way, all anamorphic wide screen movies will project on the screen with a constant width which should be set up to be the width of the screen.

    You really need only a second projector setting for 4:3 material and a third projector setting (zoom) for non-anamorphic material of aspect ratio 1.78:1 or greater.

    Thanks for the advise guys. I guess I can live with black bars on the screen. I have to live with my 35' 4:3 T.V. I'm sure I can live with black bars on a 96' screen.[​IMG] I don't know a great amount about projectors. I guess I will just have to read the manual and play around with it to get it to work at the best level.

    Thanks again![​IMG]
