Enjoy HDR UHD Blu-ray discs on your compatible display with the LG UBK90 HDR UHD Wi-Fi Blu-ray Disc Player. It supports HDR10 and Dolby Vision to help provide a wide color gamut when used with compatible content and displays. High-resolution audio formats such as Dolby Atmos, Dolby TrueHD, and DTS-HD Master Audio are also supported for a dynamic multi-channel surround sound experience with additional compatible equipment. The USB port allows you to connect devices such as thumb drives and external HDDs for playback of multimedia files. Its optical audio and second HDMI outputs allow you to feed multi-channel sound to nearly any audio system. Dolby Vision: Unlike HDR 10 which contains static metadata, Dolby Vision adjusts brightness, color, and contrast automatically for each scene (supports 12-bit color and 10,000 nits). Dynamic metadata carries information that maps every image to your TV's display capabilities, so you see more of what the content creator intended. As a result, Dolby Vision delivers incredible brightness, color, contrast, detail, and dimensionality.
