Hey all -
THis is my first time here... I have been lurking for a while, I hope to contribute sometime, but I have a noob question for ya'll!


I've asked this question to a couple AV guys, none seem to be able to confidently answer it.

WIth my 9x12 FF screens, those are built with the intention of using a 4:3 aspect ratio, correct? So when I am projecting simple Powerpoint out of a laptop, I can fit the screen.

So how is it that I am able to fit that same image perfectly to a 10x10 cradle screen? Since 4:3 isnt a perfect square - why does it fit?

Perhaps you are only pulling 7.5' of screen up out of the cradle.

[Tim McMillian]

Right, Ok so I'm not crazy (just not paying enough attention). Shooting a 4:3 image onto a fully extended 10x10 screen shouldnt fit properly, correct?


So why do they make square screens? Would that be a ... 1:1 aspect ratio?

Yup, 1:1. It's a holdover from the days of overhead projectors and slide shows where some slides would be rotated 90 degrees and need that vertical height.

Ok, great. Hey thanks for the quick response and help.
