True 4K UHD Resolution
Ultra HD 4K resolution delivers sharper, life-like images and richer colours – allowing you to sit closer to the screen and enjoy a more immersive experience.
Our DLP projectors provide CTA (Consumer Technology Association) approved True 4K UHD resolution, capable of projecting 8.3 million on screen pixels. That’s four times more detail than Full HD and twice as many from competing technology, which only delivers 4.1 million pixels.
HDR and HLG compatible
Capable of receiving and displaying both HDR10 and Hybrid Log Gamma (HLG) HDR content. This Optoma projector allows you to see far more detail and texture. Objects look more solid and lifelike and the extra detail creates a greater sense of depth.
Amazing colour
Watch your movies, TV shows and play games with stunning colours in any environment. Optoma projectors provide reliable performance suitable for any content and environment. Our home projectors are capable of reproducing the Rec.709 colour gamut, the international HDTV standard to guarantee accurate reproduction of cinematic colour exactly as the director intended. Or more saturated colours for a punchy looking image, great for gaming and animated movies.
