Is the Optoma GT3500HDR good for a bright room?

Yes. At 3,800 ANSI lumens it is bright enough for a room with some daylight, especially on a proper projection screen. A dark room still gives the best contrast.

Does it need a special screen?

It works on a plain white wall, but an ultra short throw or ambient-light-rejecting screen gives a sharper, brighter picture and better contrast.

No. The native resolution is 1920 x 1080. It accepts higher-resolution signals and shows HDR content, but the image is Full HD.

How far from the wall does it sit?

It is an ultra short throw design, so it sits close to the wall and throws a large image from a short distance. Check Optoma's throw distance table for the screen size you want.

Do I need a separate sound system?

The built-in speaker is fine for casual use, but a soundbar or AV receiver gives much better sound for movies and games.

Expect the projector, a power cable and a remote. Check the listing for the exact accessories included.
