Hi,

I have a da-lite model b (80x45) screen. When I play dvds (patriot, crouching tiger) and position the projector so that it uses the full width of the screen, I get black bars on top and bottom of the screen (IOW, the entire height of the screen is not used). Here is my setup:


HTPC w/ Radeon AIW

(desktop 1024x768, true color, 70hz refresh)


ATI player 7.1 (set for widescreen)


LT150 (native mode or resolution)


any help would be appreciated.

cthd, the patriot are not 16:9 (1.78:1) ratio movies, they are 2.35:1, so they will still have black bars top and bottom.

thank you.

does that mean they are not considered anamorphic or does anamorphic encompass serveral aspect ratios?

 

[TotallyODD]

With regards to dvd, anamorphic doesnt refer to any particular aspect ratio (can be 1:78, 1.85, 2.20, 2.35 etc.), but is the way the frames are stored on the disk.


With regard to physical films, anamorphic generally refers to 2.35 (and a few other) aspect ratio films.

Very few, if any, films are shot in 1.78 (16:9). Most are either 1.85 or 2.35 and with either of these formats you will have black bars unless you overscan the 1.85 movies. Overscanning is what I chose to do on 1.85. HDTV is of course 16:9
