Vivitek launches a compact 4K UHD projector option-- the HK2288, built around a recently developed TI 0.66-inch 4K DLP DMD chip able to generate 8.3 million individual pixels.
The projector also offers DLP DarkChip3 and BrilliantColor refinements for optimal black levels. Meanwhile eXpanded Pixel Resolution (XPR) technology uses 4.15 million (2716x1528) mirrors capable of switching over 9000 times per second to deliver two discrete pixels for each mirror per frame, reformulated through video processing to map and reproduce a native 4K image.
The result, according to Vivitek, fully resolves a 4K 1-pixel line pattern and "is indistinguishable from native 4K projection-- unlike pixel-shifting techniques employing standard 1080p chips."
