Confused about projector screen size

[BoomDog28]

I bought a short throw. 1085st. I'm trying to max my screen as much as possible. I ran some test and the size to viewing distance ratio works for me. The projector throw aspect is 16:9. For 16:9 content, that works fine. However when I play a blu ray in 2:40:1, the height is shorter. So my question is if I buy a screen in 16:9 ratio in white, will I have white bars on the top and bottom of the screen during movie watching? If I buy a 2:40:1 screen, my HDTV viewing and 16:9 content will be off the screen?.

Am I missing something?

One thing you are missing is projector screens are really black not white. The are designed to work in darkened rooms and there surface reflectivity is treated so it gives the best black response when there is no light and a nice white with lots of light. Imagine your watching a horror movie and the guys flashlight starts failing. You want to be seeing lots of black.

So in summary the screen should look black unless you turn all your lights on so you should get black bars just like a normal tv if the aspect ratio is wrong.

This is a 16:9 projector. When you select the anamorphic mode, it just means that when the source is playing anamorphic material, you'll get no black bars and when the source is 16:9 you will have black bars.

Don't buy an anamorphic screen. To truly do an anapmorphic setup you need, A)the right room, B) a projector that is anamorphic friendly (which yours is not), C) an anamorphic lense (pretty pricey), and D) usually a lense sled.

Get a good 16:9 screen, leave the aspect ratio as either 16:9 or auto and get a bigger screen if you want to see more image and less black bars.

There are some fixed lenses from Panamorph that are almost half the price of sled-base models, and they perform quite well. You'll need to select the model that best fits your projector's throw distance.
