DLP®️ BrilliantColor™ Technology
For UHP lamps, this technology is able to achieve up to 50% improvement in brightness over traditional three color solutions. BrilliantColor technology offers up to six-color processing enabling a wide color gamut and making it possible to produce over one billion colors.
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.
[ Game ] Display Mode 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.
HD28e is the first choice in the Optoma Game Master series. It comes with “Enhanced Gaming” mode. Gamers enjoy low-latency between operation of controls and win the game in milliseconds.
Note:
1.When input signal is 1080p@60Hz, Enhanced Gaming Mode can be used. Output display 1080p@60Hz, Input lag 16ms.
2.In order to reach minimum response time, when using Enhanced Gaming mode, the features such as keystone correction, image shift, and edge mask will be disabled.
Input lag & Gaming Performance
Full 3D
HD28e supports HDMI 1.4a 1920×1080 3D Blu-ray 3D movies, digital television, and gaming with super high refresh rate of 144Hz. Images do not appear in a series or shake, reducing viewing fatigue.
Auto Display Mode for 3D
Optoma provides “3D” display mode to resolve the issues related to variations in brightness of 3D images due to overlapping signals and use of specialized lenses. When a 3D signal is received, the system directly switches to [3D] mode to elevate image brightness and contrast.
Projecting on Any wall
Six color compensation are provided to suit different types of wall spaces in the home and avoid distortion of colors. Even in the absence of a projection screen, images can be viewed on a wall space with the most accurate color gamut.
