Why is my BenQ monitor locked at 2K (QHD) 60Hz and not showing 2K 144Hz when connected to a Mac M1?

04-09-2021


For EX2780Q:
The new M1 CPU platform from Apple may cause the resolution and refresh rate to be limited to 2K 60Hz when connected via USB-C. In order to fix this compatibility issue, a new firmware update is needed for the monitor. If there's any further question concerning this issue, please contact BenQ Support.
