I'm having a heck of a time understanding projectors and screen sizes, so I was hoping someone could point me in the right direction to start to understand this stuff. I know about the different formats (4:3, 16:9, 2.35/2.4:1), and that screens come sized for those, as do projectors, and I read that you can get different optics for your projector to natively support different formats.
But, I really don't understand how it works. Let's pretend I buy a 16:9 screen & projector. What happens when I put in a BluRay and it's 2.35:1? Will it just show it in that format, and then there will be "white bars" above and below the picture? Or, if I had a 2:35:1 screen & projector, and I put in 16:9 content, would it show a shrunk down version of the 16:9 content, scaled to fit within a 16:9 block on the 2:35 screen?
I'd appreciate any leads. Thank you
