No 60 Hz on Samsung U32J59x Monitor
I just hooked up a Samsung 32" monitor to my MacBook Air M1... spent an hour trying to get 60 Hz out of it but it was blurry and 30 Hz was the only choice. Swapped cords, got frustrated, searched a while.
Then... THIS WORKED: Use the HDMI 2 port on the monitor instead of HDMI 1.
The full detail: Samsung LU32J590UQNXZA 32" 4K UHD 60Hz Monitor.
This trick is probably in the manual somewhere, but...
I'm posting this in case it helps someone else.
MacBook Air 13″, macOS 13.0
