I bought this one from AliExpress: https://www.aliexpress.com/ite…=a2g0s.90423126.96.36.199Lh9I
It works fine, supports 4K, HDR, CEC, HDCP, EDID Management. You can connect one 4K and one 1080p device to it and still get 4K on the device.
How did you configure the splitter DIP-swiches? EDID MIX?
Bought the same splitter, but struggling to get it to work at 4k@60Hz.
I can still only get 4k@30Hz with the RCA-converter plugged into the splitter. Tried a bunch of different DIP-switch settings, but nothing.
Summary of my setup:
Shield TV (2015) connected to input on Denon AVR-X1200 Receiver. Receiver output goes to splitter input, and output1 to TV Panasonic TX-65CX802B and output2 connected to SSRiver HDMI-2-RCA.
