Question about AOC U2790PQU LED IPS 27" UHD 3840x2160p 50M:1 (typ. 1000:1) 350cd 5ms HDMI2.0
Why can't I get 60Hz with this monitor on my new 16-inch MacBook?
Because Samsung includes an HDMI cable as an accessory that is no good. Buy a high-quality cable and set the input to HDMI2, because only this supports 60 Hz.
Good luck!
