Hello, everybody.

I've been using the Sonoma beta since June with almost no issues. The Mac Mini is updated up to the latest beta, I think it was September 11th.

Two days ago, I started having a weird issue. I have the computer connected to a BenQ 4K monitor using USB C - USB C at 3840x2160 resolution. But every few minutes, the resolution changes to 1680x1050.

Things I've tried:

- Restartingthe Mac Mini
- Restarting the monitor.
- Going from USB C - USB C to USBC - Displayport (cables are connected directly to the Mac Mini, no dock in between)
- Googling around for similar issues.

I'm going to switch to HDMI for now and see if it works, but I'd prefer not to because I use the HDMI input in the monitor for other computer.

Has anybody got any ideas?

Thanks in advance!
