Is the Ultimea Poseidon E100 really 4K?

No. Its native resolution is 1080p. It accepts 4K input and downscales it, so you get a sharp 1080p image, not true 4K detail.

How big an image can it throw?

From 20 to 300 inches, with a 1.2:1 throw ratio and 50-100% zoom. A 100-inch image needs roughly 8.7 feet from the lens.

Does it need a streaming stick?

No. Google TV is built in, and it also supports AirPlay, Miracast and Chromecast from phones and tablets.

Ultimea rates it at 25 dB, which is quiet enough to sit near during a movie. The built-in speaker is basic, so plan on external audio via optical or 3.5mm.

Is $699 a good price?

It is the best new price across 4 stores as of November 6, 2026. Check the price history before buying to see whether it has dropped lower.

Can I mount it on the ceiling?

Yes. It supports front, front ceiling and rear ceiling mounting, and auto keystone corrects the image after mounting.
