The Ubuntu thing working flawlessly throws me off though. It'd be easy to put blame on the hub, but clearly there's something else going on. I've also managed to add a few frequencies between 30 and 50Hz (at 4k) but those don't work at all.

The problem is the Intel graphics driver for Windows thinks the connection doesn't support HDMI 2.0 for some reason, while the Linux driver might not be doing the same checks. Is this a monitor or a TV? Some TVs have a setting that needs to be enabled for HDMI 2.0.

And as expected, USB-C to Displayport works flawlessly at 4k@60Hz. Glad that it works, but disappointed that now I have a hub with a useless HDMI - had I known, I'd have bought one with DP.

Does anyone have any idea why Windows causes issues with the HDMI connection?
