The UHD60 is brighter than the Epson and BenQ I compared it to in this review, with a 3,000-lumens spec. That allows it to better fill larger screens and compete against ambient light. Optoma also sells the less-expensive 4K resolution UHD50, which uses the smaller 0.47-inch chip and has 2,400 lumens.
The UHD60 sits between the Epson and BenQ in terms of lens options and installation flexibility. It bests the BenQ by offering lens shift and a longer zoom, but can’t match the Epson’s power zoom and focus and dual lens shift. The Optoma also lacks 3D capability.”
