Can anyone help explain the differences here or other options that I have when I comes to screens?

Is the grain determined by how large your screen is and how far the throw distance is between the screen and projector?

My theaters are roughly 100 long and the screens would be about 30' wide.

I'm looking for suggestions on what gain screens I'd need for digital projectors for these sizes of theaters and how much or where I can purchase my screens from.

Thanks everyone!!!

Always go with the lowest gain you can if image quality is your main focus. Any .98" or 1.2" DLP projector can light up a 30' screen without adding gain to the screen.

I only buy my screens throught Lewis theatrical , the gain is how much light you need .. The higher the gain the brighter the picture . I have never been a fan of high gain screens ..

Not exactly. The gain refers to the reflectivity of the screen. If you get the proper sized projector and the proper sized lamp, you won't need a gain screen (unless you go silver for circularly polarized 3D like RealD). Most people install gain screens to save on bulb and/or projector costs. And it is at the expense of image quality :(

Very often a high gain screen is used when optimal
Lighting is not available. . Ie .. I had a 35 mm projector that had a long throw and a 90 ft screen hence we used a gain screen to get more light ..
