I was going to buy a new cable and I came across this description:
>Category 2 Certified HDMI wire supports resolutions up to 4Kx2K (UHD)
@30 Hz
https://www.cnet.com/how-to/what-is-hdmi-2-0b/
HDMI versions compared
HDMI Version Max Resolution Max 4K Frame rate HDCP 2.2 HDR WCG Hybrid Log Gamma Dynamic Metadata
1.4 4K 30Hz No No No No No
2.0 4K 60Hz Yes No No No No
2.0a 4K 60Hz Yes Yes Yes No No
2.0b 4K 60Hz Yes Yes Yes Yes No
2.1 10K 120Hz Yes Yes Yes Yes Yes
"Category 2" implies HDMI 2 but the "Max 4K Frame rate" of 30Hz says it
is HDMI-1.4.
