The LogiLink 4K HDMI switch allows convenient switching between three HDMI input sources (video camera. DVD/Blu-ray player. game console. streaming box. etc.) via remote control. intelligent automatic detection or alternatively via switch on the switch itself. Annoying plugging of cables is a thing of the past. Thanks to Ultra HD (4K/60 Hz). you can experience media content in brilliantly sharp resolution with support for HDCP 2.2. HDR. CEC and 3D. The audio transmission in LPCM 7.1. DTS. Dolby Digital. DTS-HD Master Audio and Dolby TrueHD also leaves nothing to be desired.
