The LogiLink 4K HDMI switch allows for easy switching between four HDMI input sources (camera, DVD/Blu-ray player, game console, streaming box, etc.) via remote control, intelligent automatic detection, or alternatively through a switch on the device itself. The hassle of unplugging cables is a thing of the past. With Ultra HD (4K/60 Hz), you can enjoy media content in stunningly sharp resolution, supported by HDCP 2.2, HDR, CEC, and 3D. The audio transmission in LPCM 7.1, DTS, Dolby Digital, DTS-HD Master Audio, and Dolby TrueHD, along with the connection of an external AV receiver (ARC), leaves nothing to be desired.
