The Smart and Simple Way to
Watch Movies
Watching movies is easy. With the touch of a button, switch to “Cinema” display mode, image performs true to life with high contrast by the specific Gamma curve. At the meantime, it activates Brilliant Pulse on Red function to make the light pulse projects on the red segment of the color wheel. Red enhancement makes images more natural skin tones, better color saturation and more enjoyable viewing experience.

Dynamic Black
Dynamic Black can accurately control light bulb output power and automatically adjust it based on different image brightness. There is no need to use an aperture ring to adjust for dark scenes. With Auto Gain function, details are more pronounced and an increase in contrast ratio of nearly three times is achieved. This means that images appear true to life with dramatic increase in contrast.

Something Hidden in the Dark
Shadow Boost. All-day simulations
In Optoma’s Color Lab, simulations were carried out for gaming in different ambient light settings to calibrate and boost the details in the dark and develop the exclusive “Game” display mode. This means that gamers can avoid getting stuck at a certain level, as they can clearly find the gimmick hidden in the dark.
Lag-Free Gaming
