Verdict

The Ricoh PJ UHL3660 is a professional 4K UHD ultra-short-throw laser projector utilizing a 0.65-inch DLP chip and 4-way pixel-shifting technology to deliver exceptionally sharp visuals with a 5,000,000:1 dynamic contrast ratio. Key characteristics include a high brightness of 6,500 lumens powered by dual-laser OptiBright technology, an ultra-low 0.24:1 throw ratio capable of projecting a 160-inch image from just 15 inches away, and an IP6X dust-proof sealed optical engine for 24/7 operation. Major pros include a maintenance-free lifespan of up to 40,000 hours in Long Life mode, 360-degree and portrait mounting flexibility, and robust connectivity with HDMI 2.0, HDBaseT, and wireless Miracast. Some cons include a lack of built-in smart TV features, no 3D support, and a non-backlit remote control.
