    General Screen Discussion
    I stumbled upon an old idea from 4 years ago in a 3D model of my old room that included a projector setup and a mirror that bounced the projected image to extend the available throw distance and thus increased the size of the image in confined areas. Setting aside a) Keystone distortion b) The...

    Hello, I'm a total newbie to projectors and screens. I got very cool all in one projector for my birthday and then realized it didn't have lens shift on it nor was it 1080p so we exchanged it for the Epson 8350 so we can use it at an angle. The room that its going in is large. It's 24' x 24'...
