LG 27UP600 only getting 30 Hz on M1 MBA

[rm5]

I have an LG 27UP600 monitor that I normally use with my 5,1 Mac Pro, but decided to test it with my M1 MBA. I hooked it up, and it connects just fine; however, I'm noticing I can only get 30 Hz out of it, compared to 60 Hz on the Mac Pro. It's connected via HDMI to a USB-C hub. Maybe the hub only supports 4K at 30 Hz? I have no idea. Any ideas why, or how to get 60 Hz like I do on the 5,1?

Was having the same problem and just figured it out. You just have to go into the monitor's built in settings and turn on freesync!

Great, I'll have to try this when I get home today

@shammin5169 I tried turning on FreeSync and no dice—still stuck at 30 Hz. I also noticed there's no HDR control in System Settings like there should be... At this point, I'm guessing it's an issue with the hub I'm using.

Yep, it's the hub—I just looked at the specs. Gosh, this sucks!!
