LG just released a 42” OLED tv I’ve been considering using as a monitor. It’s model C2. I know it’s a bit unusual but it might be worth looking into!

Been trying to use a C1 with my M1 MacBook. I think I'm going to return it.

  - There's no way to get above 60hz.
  - Have to use an HDMI connector because the C1 doesn't support thuderbolt or displayport.
  - The sound doesn't work for some reason.
  - The TV features get in the way a bit, menu overtop of things when you turn it on.

This is all kind of Apple's fault for not including HDMI 2.1 support.

I might get something referenced on this site: https://tonsky.me/blog/monitors-mac/

Just get a USB-C/Thunderbolt HDMI adapter that supports 120Hz - like this one: https://www.amazon.com/Sabrent-Function-Resolution-Thunderbo...

The nice thing about having expansion ports is you aren't restricted to what Apple bundles with the machine.

Unfortunately there is something preventing this from working, not entirely sure what.

A lot of people have tried, and nobody has gotten 4k@120hz working on an M1 over HDMI (or a cable converted to HDMI).

Now that you mention it, I have had a lot better luck with Display Port than I have with HDMI - will have to go to a friend that has a high refresh monitor and test out my display port hub.
