And if you have a 16:9 image on a 2.35 screen, does it have built-in masking of the sides to make them as black as possible?
If you use a "normal" lens (no anamorphic widening), the 16:9 content will not use the sides of a 2.35 screen at all, and so any light leak you are seeing over there can't be fixed by anything the projector or a video processor can do. I.e., no pixels are being displayed over there. That portion of the screen is reflecting ambient light in the room, including light reflected back onto the screen from the walls, etc., due to the active portion of the image.
If you use an "anamorphic" lens which optically widens a 16:9 image left to right so that it fills a 2.35 screen, then every portion of the screen is illuminated directly by the projector. When playing 2.35 content, you can apply a uniform vertical stretch in the D2v so that the content fills the 16:9 output frame sent to the projector -- i.e., no wasted pixels just holding letter box bars. Now this distorts the image: Circles now look like tall ovals. But the anamorphic lens optically widens that 16:9 input frame to the 2.35 image it throws to the screen so things now look correct again (circles look like circles, and the image fills the 2.35 screen top to bottom and left to right). You do the vertical stretch in the D2v using a Custom Crop and Anamorphic Scaling. See the "Fun With Custom Cropping and Scaling" post links in the first post of this thread for details. When playing 2.35 content this way to your 2.35 screen there are no unused areas of the screen.
The problem comes if you play regular 16:9 content using that same "anamorphic" lens. If you leave the Custom Crop in place, the top and bottom of the image will be discarded -- i.e., the portions that used to be the letter box bars when you were watching 2.35 content. The image will fill your screen left to right and top to bottom, and it won't be distorted (circles look like circles), but you can't see the top and bottom portions of the original 16:9 content frame.
If you turn OFF the custom crop, but still leave your anamorphic lens in place, the image will fill your screen top to bottom and left to right, and you won't lose any portions of the image, but the anamorphic lens will stretch the image left to right (which is why it fills the 2.35 screen left to right) and so the image is distorted (circles now look like wide ovals).
The "correct" solution is to swap out your anamorphic lens with a normal lens. You'll now see the 16:9 content filling your screen top to bottom, and without distortion, but a portion of either side of your 2.35 screen will be unused. I.e., back to the first case above. Again, done this way the projector is not illuminating the sides of the screen so any light you see off of that is ambient light and there is nothing the projector or any video processor can do to alter that.
An alternative, "less correct" solution is to leave the anamorphic lens in place and apply a "squeeze" to the 16:9 content so that it doesn't use a portion on either side of the 16:9 output frame being sent to the projector. This distorts the image of course: Circles now look like tall ovals. But your anamorphic lens now optically widens that and so you again see an undistorted 16:9 image that fills your screen from top to bottom and leaves a portion of the 2.35 screen unused on either side.
However in this "squeeze" case, the left and right sides of the screen *ARE* being directly illuminated by the projector. I.e., there are actually pixels being thrown by the projector to those sides.
Now when the 16:9 content is squeezed this way, the unused portion of the 16:9 image frame on either side is filled with black pillar box bars. The pixel values being sent to the projector in those bars on either side are indistinguishable from "black". If the projector's black levels are not dark enough for your taste then you will see dark gray in the unused portions on either side of the screen but there is nothing that ANY video processor can do to alter that. It can't send "negative" pixels to the projector that will force the projector to magically throw less light for those pixels than its inherent black level output limit. Some projector technologies are worse than others in terms of how little light they throw for "black" pixels, but again if your projector, properly set up, still throws dark gray instead of black for a "black" pixel, there's nothing any video processor can do to correct that.
Folks use curtains that can be partially drawn on either side to help in such cases. Curtains are also used to cut down on ambient light reflection in unused portions of the screen.
But there's yet another problem with this "squeezed" approach to 16:9 content. When you squeeze the 16:9 content, each line across the image has to fit into fewer pixels! Why? Because you are using the pixels on the left and right of the output frame to hold your pillar box bars that result from the squeeze. The NUMBER of pixels on each output line doesn't change, it's just that you are now wasting a bunch of them to hold black pillar box bar pixels.
And that means you are discarding horizontal resolution. A lot. And once discarded there's no way to get it back. The anamorphic lens will optically widen the image back to a 16:9 shape, but the horizontal resolution within that shape can't be restored that way or any other way.
And so, Anthem has chosen to NOT OFFER a 16:9 "squeeze" option in their video processor.
It sounds like you are saying you are using just such a "squeeze" option in your CrystalIO. So the short answer to your question is that the Anthem will not do that. By design. But understand that every time you watch 16:9 content using such a "squeeze" option along with your anamorphic lens you are throwing away image quality. And also understand that despite how they might have written it up, there's nothing the CrystalIO can do in the black pillar box bars created as part of that "squeeze" which will make your display throw anything blacker than its own, inherent black level limit for those pillar box bar pixels.
My recommendation is that you should investigate one of the lens options that makes it easy for you to shift between an anamorphic and a normal lens when you want to view 16:9 content on your 2.35 screen and stop using the "squeeze" option. If even with that you have too much ambient light reflection from the unused sides of the screen, consider curtains that can be partially drawn to cover the unused portions on either side of the screen.
