Verdict

The ViewSonic PX800HD is a 1080p Full HD ultra-short throw DLP projector featuring 2,000 ANSI lumens of brightness and a high 100,000:1 dynamic contrast ratio. It is specifically designed for home cinema, utilizing an RGBRGB colour wheel with SuperColor technology to achieve Rec. 709 colour accuracy and supporting a massive display size of up to 150 inches from just inches away. Main pros include its extremely low 16ms input lag for gaming, a unique hidden PortAll compartment for streaming sticks, and ISF-certified calibration modes for professional-grade day and night viewing. However, its 2,000-lumen output can struggle in bright ambient light, the cooling fan is somewhat audible at 35dB in normal mode, and the unit lacks modern smart features or internal 4K upscaling.
