Latest true HDMI v2.0b 18Gbps 4:4:4 4K@60Hz 1x2 Splitter with automatic 4K to 1080p down-scaler; HDCP 2.2 Compliant, does not bypass HDCP. The one input is to be connected to the HDMI source, and the two outputs are to be connected to the TVs, both TVs will share the same video and audio signal. Two built-in EDID modes: use Auto (to accommodate both outputs at the same time); use out1 (to fully utilize the display connected to output 1 without compromising by the display unit @ output 2). In auto mode: when output 1 is a 4K HDR/Dolby Vision TV, and output 2 is a 1080P TV, the HRD/Dolby Vision will be disabled for the 1080P TV to get the best 1080P video quality, while output 1 gets 4K video. The reason is 4K to 1080P down scaler doesn't support Dolby Vision, and 4K HDR produces poor 1080P color. If both TVs are identical 4K displays, then the scaler has no effect, it will not be activated automatically. In out1 mode: the TV connected to output 1 will be fully supported and obtains Dolby Vision / HDR video as if the TV is connected to the HDMI source directly, this mode is to make sure that the capabilities of the TV connected to output1 is not comprised by TV connected to output 2.
