Optoma HD28e | Big screen entertainment
The HD28e is the successor to the best selling HD27e projector. Delivering 1080P high resolution with 3800 lumens of brightness, the HD28e provides all the essential features that you need for home entertainment.
Designed with HDMI extender, USB Power and a built-in speaker for quick and simple setup, the HD28e brings up to 15,000 hours of lamp life for great performance over comparable products and is ideal for everyday use.
With HD28e’s HDMI Link function, this is reduced to one step. After initiating the HDMI Link settings, just turn on/turn off the set top box. The projector automatically turns on/turns off. (Note:1. This function is only supported at the external device end and with CEC-HDMI controls.2. Operational items: Power on/Power off)
HD28e incorporates DLP projection technology and uses the latest Texas Instruments 1080p DMD chip & DDP4422 GPU.
HD28e incorporates RYGCWB color wheel and performs sharp 1080p high-definition images. Through Optoma’s specialized color calibration and mixing technologies, enjoy 3,800 lumens of brightness and outstanding color with accurate HDTV standard Rec. 709 color gamut. This is a cinema-quality projector for use at home.
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.
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.
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.
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.
