True 4K UHD resolution
Ultra HD 4K resolution delivers sharper, life-like images and richer colors - 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.
Lights on viewing

*With no direct sunlight or lights directed on screen.

Four corner correction
Four corner correction enables the keystone of the projector to be adjusted in both the vertical and horizontal plane, so you can individually warp each corner of the projected image to make it perfectly square. Ideal for uneven walls or in spaces where the projector placement is awkward or limited and needs to be installed at an angle.
Our backlit remotes are designed using subtle white LEDs to light up the buttons, making it to see and operate,
especially in the dark
