I’ve checked it, just to be sure, it’s definitely a 2.1 cable, but unfortunately the cable doesn’t matter in this case. My monitors are good, but they’re older. HDMI 2.0/2.1 wasn’t around back then. I get good refresh rates over DisplayPort (I believe they have DP 1.4), and my RX 6800 XT had three of those, so I just naively assumed a 9070 XT would as well.
