Just installed 11.1 on my Ryzentosh and have been greeted with 30khz on my 28” 4K monitor 🤦♂️ No option to increase and switchresx just ain’t behaving for me 😱Hopefully with a fix for display refresh rates and resolutions when using an external monitor. 11.1 has been terrible - Big Sur generally boots into a lower resolution and/or refresh rate on the external display ever since 11.1 was released (though there are reports of this issue cropping up in the betas) - was absolutely fine with 11.01. Running a MacBook Pro 16" here with a 27" BenQ monitor and USB-C connection, so nothing too exotic.
