Television broadcast (HDTV) is NOT in the 2.35:1 ratio, it is 16:9 (1.85:1). A lot of movies are 1.85:1 and most all the "big" movies are scope at 2.35:1 or wider. If you use the zoom feature of some projectors you can have a 2.35 screen and zoom out for HDTV.....but you'll have black bars on the sides. Most folks prefer to have a masking system to cover up the sides so you can't see the side bars while showing a picture narrower than scope.
Constant Image Height. Refering to those of us you have (or will have) a scope width screen and use an anamorphic lens in the light path to stretch the image to the correct width....after a processor stretches the image veritically to remove the top and bottom black bars.
3. Any other things I should know about this setup that would help.
Ideal projector needs include lens memory and image processing (for the stretch) unless you use a stand alone video processor or player that will do the stretch.
Using the zoom method you don't need processing but lens memory, so you don't have to re adjust everytime you switch between ratios.
Scope is a more immersive feel. While designing my theater (still building) I painted on a HDTV ratio on the screen wall and it gave me the feel of just a big TV room. Then I widened the ration to scope and thought....this feels like a real cinema now. Plus if you do like me and use an acoustically transparent screen, you can go wider and place your speakers behind the screen. Now my room will REALLY feel like a theater!
Lens option = more expensive but you generally have a brighter picture
Zoom option - less expensive, but you are now projecting black bars outside the borders of your screen
Finally, read as many posts in this area as you can stand and get educated on CIH, scope, anamorphic lens, zooming, lens memory....ect.
BTW there are cheaper ways to do the lens option than a $6000 state of the art lens and electric slide. You just have to be patient and shop the preloved market. (think between $800 and $1500 range)
