Guys,
I just bought my Mitsubishi HC4000 projector and I just love the picture it thows up. I have a 15x19ft room and the projector will be mounted at 13.5 ft. At this distance, the biggest 16:9 image I can get is 130" diagonal (64" x 115"). Seating is between 14 to 16 feet.
Now, my dilemma is whether to keep this image size or do a CIH where the screen size will be 49" x 115" i.e. 125" diagonal 2.35 aspect ratio.
Pros of 16:9 screen:
1. Huge IMAX like effect when watching 1.78 content (XBMC, TV Shows etc).
2. Can play subtitles of 2.35 movies since black borders are not cut off while zooming under CIH system.
3. Full 1080p panel of projector is used. Brightness is a bit higher.
Cons of 16:9 screen:
1. Placement is more difficult due to the offset and huge image size. I haven't ceiling mounted it yet, so I don't know whether I can accommodate this picture size.
2. Black bars on top and bottom when watching 2.35 content
3. Non HD content or poorly encoded content will not be impressive as flaws get magnified.
Pros of 2.35 screen (under CIH mode):
1. No black bars when watching 2.35 content.
2. Cinema Scope screen will look more cinematic than a 16x9 screen in a home theatre. However this is more of a novelty factor because I will continue to watch 2.35 content at 49 x 115 size, so the image size will not change irrespective of screen size.
Cons of 2.35 content:
1. 16:9 content is shrunk down when the screen size is set as Cinemascope. The image size is 49" x 87" which is 100" diagonal. When compared to the original 16:9 130" diagonal screen, this significantly seems smaller. Definitely no IMAX effect.
2. Subtitles get cut off when watching 2.35 content when the subtitles are placed in the black bars.
3. Full panel of the projector is not used and there is a slight dip in brightness.
4. Black bars on the side when watching 16:9 content.
From the above arguments, the 16:9 screen seems to be in the lead and the CIH seems to be a tough call. How did you guys work this out?

). However, when zooming the aperture of the projector's lens changes and you may find the increase in brightness compensates, so it's not always the issue you might think. With a JVC projector, you can just set the iris differently for the two ARs and match them if you wish as I do.
