Cinemascope on VAVA?

Hi all. New to forum. We are moving into our new house and theater room. I was going to buy a Stewart 2.35:1 cinemascope screen from projectorscreen.com. However, their customer service told me VAVA wouldnt project in cinemascope. That is wrong, correct?

The Chroma only supports 16:9 projection.

It can of course play back 21:9 content, but with black bars at the top and bottom (letterboxing).

Having it project on a 21:9 screen will cause bright or let’s say grayish areas above and below the screen, I would not recommend it.

Thank you for your reply. Your reply will definitely help other customers.
