"This projector prioritizes software convenience over the fundamental need for a bright, clear image."
Native 1080P with 4K Support means the device's physical display chip is 1920x1080 pixels. It can accept a 4K video signal and shrink it to fit, but the final image you see is standard high definition.
This product is for a buyer whose top priorities are a built-in smart TV interface and automatic setup for casual viewing in a completely dark bedroom. The short-throw lens is a legitimate advantage in cramped spaces.
Anyone who needs to use a projector with even a small amount of ambient light should skip this. Users sensitive to slow, laggy software interfaces will also find the 1GB of RAM to be a significant bottleneck.
