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.
Amazing color
Watch your movies, TV shows and play games with stunning colors in any environment. Optoma projectors provide reliable performance suitable for any content and environment. Our home projectors are capable of reproducing the Rec.709 color gamut, the international HDTV standard to guarantee accurate reproduction of cinematic color exactly as the director intended. Or more saturated colors for a punchy looking image, great for gaming and animated movies.
Enhanced gaming mode
Enhanced gaming mode optimizes your projector for maximum contrast and vivid colors to capture every detail. It also reduces input lag down to as little as 4.2ms (1080p 240Hz) for lightning-fast response times.
Note: When this setting is enabled some settings will be disabled. Please refer to the user manual for more information.*

Get right inside the action with the most immersive experience possible – a huge screen up to 300in.* Far larger than the average TV, split-screen multiplayer games are more enjoyable to play on the big screen.
Integrated speaker
Complete your home entertainment experience with the convenience of a powerful built-in speaker for exceptional sound quality and an easy set up without the need for costly external speakers.
24p
Most movies are shot at 24 frames per second (fps). To preserve the purity of the original image, Optoma projectors can accept high definition sources at 24 fps to display movies exactly as the director intended.
USB-Power
Use the USB-A port to power an HDMI dongle, such as Google Chromecast.
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.
Wall color adjustment
Don’t have a white wall or a projector screen? No problem! With the “Wall Color” setting, you can alter the projected image based on the color of your wall. With six options to chose from you can easily adjust for blackboard, light yellow, light green, light blue, pink and grey walls to get the most accurate color gamut.
Backlit remote
Our backlit remotes are designed using subtle white LEDs to light up the buttons, making it to see and operate, especially in the dark
