IMO, forget 2.35 for now. 1.78 on a 2.35 screen is a very reduced pic. Good glass is incredibly expensive. If using the zoom method that is also another can of worms, whether light control, lack of lumens, and the issue of which AR to even calibrate for.
If you sit double digit feet away from screen (from its final position) you may consider AT screens. The Seymour DIY is super affordable for instance.
If need be, I would also consider getting screen closer to ceiling, however, if you can use something like a flat black paint. You can search my posts in this subforum for paint recs.
For the future, please organize your post so that it takes us much less effort to read. Attached pics or diagrams can make this easier for us too. It takes a lot of effort to try to wade through your post, and by the time I'm done, I've used half my energy which instead could have been towards explaining more things on your behalf. Morale of the story: help us help you, thanks for considering.
