Review on Cmple Adapter Supports Ethernet Return by Jessica Turner

Finally I was able to use this on a Raspberry Pi4 and when 4k 60hz was enabled there were small green artifacts in the output. When I changed the refresh rate to 30Hz and 29.97Hz, they disappeared. It didn't seem able to handle the 12.54 Gbps needed for 3840 x 2160 60Hz 8-bit 4:4:4 video, but it could handle 6.18 Gbps for video. 3840x2160 30Hz 8bit 4:4:4. I don't know if this is due to anti-interference, but if the cable was damaged I wouldn't expect a sharper image at a lower refresh rate (less SW usage). I ended up using a different cable and micro to HDMI adapter with no issues at 4k 60Hz to confirm this.
