Each micromirror can be switched over 9,000 times in a second to allow on-screen Two completely different and unique pixels are generated in each frame to achieve full 4K UHD resolution (3840 * 2160).
As 4K video brings a huge amount of data, so HK2288 is equipped with dual DDP4422 data processing control chip, equivalent to the computer's dual-core CPU, simultaneous processing UHD 4K large pixel and color data, the output 3840 * 2160 resolution, 60Hz screen refresh rate, while the average projector is only up to half of its (30Hz) refresh rate, has always brought smoother picture experience.
HK2288 brightness of 2000 lumens, contrast up to 200000: 1, to show a better grayscale details. Color, the use of 6-segment (RGBRGB) color wheel and loaded brilliantColor technology, enhanced color and dark performance, support for REC709 color Standard, supports HDR10 High Dynamic Range Imaging. Vivitek (Vivitek) China household products manager Zhang Guohuai said HK2288 actually supports up to 12bit color processing, the future with 4K HDR video rich, do not rule out support for Dolby Horizons and other higher levels of HDR standards.
