What is a Fresnel screen and why use one with a UST projector?

A Fresnel screen has concentric lens ridges that redirect light from a projector placed close to the wall toward the viewer and reject light coming from other angles. That keeps the picture brighter and more contrasty in a room with some light than a plain white screen.

Does the 160-degree viewing angle mean everyone sees the same picture?

It is a wide angle for an ALR screen, so viewers seated well off to the sides still see the image. Fresnel screens do dim and can shift color toward the edges, so the center seat is still the best one.

Will it work with my ultra-short-throw projector?

It is made for ultra-short-throw projectors, which sit close to the screen. Check that your projector's throw ratio and image size match the screen, since Fresnel screens need the projector positioned as designed.

What aspect ratios and sizes are offered?

The screen comes in 16:9, 4:3 or a custom ratio, and a 100-inch size is listed. Confirm the exact size and ratio you need before ordering.

Yes, it is listed as 4K compatible, so it will resolve a 4K UST projector's image without the screen limiting detail.

Is it good in a bright room?

It rejects ambient light, so it handles a room with windows or lamps better than a standard white screen. It is not a substitute for a dark room, and performance falls off as light hits it from the sides.
