"A projector whose best feature is its OS, undercut by misleading resolution and placement claims."
The '4K Support' and 'HDR10' mean the projector can process those signals, but it projects a downscaled, likely 1080p image. Its low brightness further means any visual benefit from HDR will be minimal to non-existent.
This is a fit for a buyer who wants a portable projector for casual use in a pitch-black room, like a bedroom ceiling. They must prioritize the convenience of a built-in Google TV OS and understand they are paying for a standard-throw, 1080p projector, not the 4K UST device advertised.
Anyone needing a projector for a living room with ambient light, expecting a true 4K image, or wanting an actual ultra-short-throw unit should look elsewhere. The deceptive marketing is a primary reason to be cautious if you are not an expert buyer.
