Just received new monitor Dell S2418HN for my MSI RX480 GAMING X 8G (latest driver 17.9.3 installed).
Monitor is connected via HDMI 2.0. 1920x1080 at 75Hz and Freesync are supported by this monitor model.
But i can't get it to perform at 75Hz! Windows and AMD Crimson Driver are showing 59Hz and not let me change it to 75Hz.
OS is Windows 10 x64
Latest monitor driver and Dell software are also installed.
So the question is - where and how to set refresh rate to 75Hz?
I always thought GPUs can automatically detect max frequency from monitor and set it initially...
