Ultra Short Throw Projector Screens FAQ’s

Q: I’d like to buy an Aeon CLR® 3 screen but my UST projector is 120 inches. I notice that your screens are oversized by a few inches such as 103” versus 100” or 123” vs 120”. In my case for example, I do not want an empty screen section, but the image to go all the way to the border of the screen. Can you advise?
