When changing aspect ratio, you have a choice and the info shows on the very top right of screen in black frame. Not noticable and changes ratio very quickly while watching a movie.

It is really easy. It seems like you were able to do most of the work and set up can be time consuming

If you go Menu>Installation>Lens Lock>Select OK>

Now you will see Zoom/Focus Lock. Change to ON
You will also see Lens Shift Lock. Change to ON.

Reason why I did this is I spent hours getting the PJ just right and my wife needs to be able to view movies easily without fear of changing something.

Youre Aspect Ratio needs to be set to Auto.
Menu>Feature> Aspect: Auto

Also set Menu>Image>Advanced Menu>OK>Screen Size>
CinemaScope for 2:35.

Now on remote you can toggle aspect ratio between Auto (2:35) and 16:9 by simple push of button.

This information was initially found by 5mark and tested by CT Wiebe. Works fantastic for CIH with Zoom which is what I am doing. Simple and easy.

Thats Correct. Once Zoomed in to my 2:35 size I lock the zoom.

You are right - when you select 16:9. It makes the 16:9 smaller in size. To tell you the truth I did not notice the black bars on sides. I did notice the 16:9 image being cropped smaller - like a shrink to fit.

I also did the blanking on the PJ and to me its pretty black. However I am in low lamp with Iris on 5 and in a very dark room.

I am still just amazed at this picture.

Moreso amazed that I build a 134" screen. Evertyime I walk into the room, I cannot believe the picture I get with this. I was using a 50" Samsung Plasma before this.

I built a temporary painted screen with Behr Silver Screen Paint and a board from HD. However, it does not looked as expected. I tried a trypod based screen loaned from my brother and althoght it is not in good shape, picture looks better, so I think the problem is my "screen". So I am looking for options....

Thks....

Once you have calibrated your HC6800, you can make those black (gray) bars darker by using the HC6800's video blanking -- the "Shutter option" capability (see below).

An Update & Reminder (edited from post #282):

SUMMARY: To use a CIH 2.35:1 screen with the HC5500/HC6500/HC6800 PJs, without an Anamorphic lens, perform the following settings (do not use any of the "Anamorphic Zoom" mode, or other zoom, options):

1.) MENU => IMAGE => ADVANCED MENU => OK (enter button) => SCREEN SIZE = CINEMA SCOPE(2.35:1)

2.) MENU => FEATURE => ASPECT = AUTO

To switch between the 2.35:1 and 16:9 modes, use the "Aspect" button on the remote -- "Auto" for 2.35:1 and "16:9" for 16:9 sources.

OPTIONAL SETTINGS (Video blanking of the black bars):

1a.) MENU => SIGNAL => USER => OK (enter button) => SHUTTER(U) = set to about 22 (increase until the black bar starts to cut off the top of the image, and back off by 1unit).

2a.) Repeat step #1a. for SHUTTER(L) -- again increase the setting until the black bar starts to cut off the bottom of the image (around 22) and back off by 1 unit.

-- The following optional adjustments can be used for video blanking of the "black" side bars for 16:9 movies:

1b.) ASPECT = 16:9

2b.) MENU => SIGNAL => USER => OK (enter button) => SHUTTER(LS) = set to about 53 (increase until the black bar starts to cut off the left side of the image, and back off by 1 unit).

3a.) Repeat step #2b. for SHUTTER(RS) -- again increase the setting until the black bar starts to cut off the right side of the image (around 53) and back off by 1 unit.

When going back to a 2.35:1 movie, be sure to reset the side Shutters (LS) & (RS) back to "0".

You have to be able to raise the image up to the top of the screen with the lens shift. In my case, I am already at the maximum lens shift limit. I would have to raise my HC5500 up about a foot, or slightly more, in order to be able to do that.

The down side of that technique is that to fill a 16:9 screen with a 16:9 image requires multiple steps -- resetting the screen size from CinemaScope (2.35:1) to 16:9 and then re-lens shifting to center that image. The other drawback is that by raising the screen, you lose the top black screen border, which means that the upper picture boarder shines on the screen case -- a distraction (even if the video blanking, Shutter, is used). Painting the off-white screen case with a dull black paint would help, of course.

Using a larger 2.35:1 screen would be a lot more convenient if we watched a lot of 2.35:1 movies. Since most of our viewing is HDTV and 16:9 movies, using my 16:9, H-P screen is a better compromise for me.
