My adapter came today and i’m using it with a RTX 2080Ti and a LG SM9000 Nanocell TV. The SM9000 is equipped with 4 full 48Gbps HDMI 2.1 connectors and i’m using Belkin 48Gbps HDMI 2.1 cables to all my devices (PC/Nintendo Switch/4K UHD Blu Ray Player and Denon AVR-X1600H eARC compatible receiver).
The CAC-1085 gives me the option to do 4K 120hz with Full RGB @ 8-bit and 10-bit colour. I can also do 12-bit @ 4:2:2 chroma sampling.
The trouble is, every time i switch any settings in the Nvidia Control Panel, the screen goes black and it does not come back on again until i have pulled out the USB power cord from the adapter then plugged it back in again.
It’s annoying to have to do that but it gets it working again. Also, if i turn HDR on, the same thing happens. Screen goes black and picture won’t come back on until i have pulled the adapter’s power cord and plugged it back in. There seems to be something wrong with the handshake. Similarly, when i’m in HDR mode and try to switch back to SDR mode, it happens again. Black screen until i power down the adapter and power it on again.
It’s nice while its working, I do admit. Text is super clear at 4k with Full RGB. And 120hz means there’s no ghosting during motion or animations which is great. I just wish I didn’t have to fiddle with the power cord so often.
