"A cheap smart projector whose main feature isn't the picture, but the licensed Netflix app."
'1800 ANSI & 4K Decoding' means the device can accept a 4K signal and downscale it to its native 1080p display, with a brightness level that is a small fraction of the advertised number.
This is for someone prioritizing the convenience of built-in streaming apps above all else, for casual use in a dark bedroom. If the goal is the cheapest possible all-in-one Netflix machine for a wall, this is a contender.
Anyone who needs to watch in a room with even minimal ambient light should skip this. Buyers seeking accurate color, sharp focus, or long-term reliability should invest in entry-level models from established projector brands.
