Mini: The ZDSSY HY300-Ultra is a compact smart projector with built-in apps, a claimed short-throw design and an adjustable stand. Its listed native resolution is 1280 x 720, so its 4K decoding support does not make it a native 4K projector. The listing says it is best used in a dark or dim room.

What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title says it supports 4K, 8K and 1080p, while detailed text specifies native 1280 x 720 and decoding of compatible higher-resolution files, and the maximum display field says 3840 x 2160 pixels. The listing also gives conflicting warranty terms, with 12 months in a feature description and 2 years in the warranty field. Confirm the selected listing details before purchase. Brightness, image size and clarity depend on ambient light and placement.
