I have my wall painted with silver Fire. I am using Mit hc5500 and pioneer BDP 51.
When I play a movie 16:9 I get black on the top and bottom of the movie.
The movie does not fill in the 16:9(excluding the projected black) dimension for a 110" screen.
The black and movie do fit the currect dimensions.
Player and projector are on auto. When I place projector in 16:9 mode it stays the same.
I am trying to mask the screen area but I first need to have the currect projected image.

Do i have a setup incorrect?
Should i mask the whole area including the projected black area?

Most widescreen movies are 2.35:1--not 16:9, therefore a large amount of black will appear on top and bottom of image. However, if there is just a couple of inches of black, then most likely the movie is in 1.85:1 ratio which is slightly smaller than 16:9. 1.85:1 was the most popular image size after theater movies changed from 4:3 (old TV size) to a wider screen. 2.35:1 was the change to CinemaScope screens--giving a more panoramic image. Check the DVD case and see what it says. If it simply says Widescreen, then you might get 16:9 or 1.85:1 or most likely 2.35:1.

thank you for your response.
I will mask off the whole area black and movie then.

If you do mask for 2.35:1, then of course when showing a 16:9 or 1.85:1 movie you'll have to reduce the zoom to fit inside the mask or obviously the image will be reduced by the mask. Or were you thinking of having several masks of curtain material maybe. People have done this with some success, but it does take some design with pulleys and horizontal curtain arrangements.

I'm pretty sure his issue is that a 16:9 Movie is not filling in his screen's perimeter. Leastwise that's what I read into it.

Under those circumstances, especially if his Movie Collection has a lot of 16:9, he can indeed solve the issue by masking the remaining non-projected upon areas top and bottom.

Of course when switching to a 2.35:1 format, he's a'gonna see Bars, but I did not read him mentioning that as his issue.

So the questions to ask are....what PJ does he have (a WXGA at 16:10?) and what are his EXACT Screen dimensions.

Those answers will elliminate the Guesswork.
