I'm using BenQ EX2780Q (native 2560x1440 144Hz) with M1 macbook pro 16gb. Tried USB-C to USB-C, USB-C to DP1.4, USB-C to HDMI 2.0 (all cables certified for 8K), at best getting 2560x1440 (low res) at 60Hz. OS is Big Sur 11.3 Beta 3, issue still persisted. Quite frustrated.
External Display 2K 144Hz issue
Hi, I have MacBook Air M1 and I am planing on buying this monitor. Did you resolve this issue?
