What to know before buying

Listing details to confirm

The listing details are inconsistent or unclear: brightness appears as both "3500 lm" and "3500 ansi_lumens," while throw distances are given as bare numbers without units. The video-format string is malformed, and customer feedback describes a howl screen, which does not clarify the screen type. Confirm these details for your setup. The listing also recommends updating firmware and the system after unboxing, including to Android 14, but the system software version is not independently specified elsewhere.

Who is it for?

A good fit for

Home theater buyers seeking listed 4K resolution, Dolby Vision and a large projected image.
People who expect to move the projector between rooms or use automatic focus and image alignment to simplify setup.
Viewers wanting multiple wired and wireless connection options for consoles, laptops, phones or audio equipment.

Less suited to

Viewers particularly sensitive to rainbow effects, given reported customer concerns.
Buyers who need confirmed throw-distance units or an unambiguous video-format specification before choosing an installation.
