My monitor max res is 3440 * 1440 , 100Hz and i can use this config very well.
The default available HiDPi res is 1720 * 720 , 100Hz (2X factor)
but that is too big, so i used SwitchResX and i have successfully made many custom HiDPi resolutions (1.5X, 1.2X ..) but all are locked to 60Hz !!
i tried many and many resolutions to make it 100Hz but no luck
How to modify/force the refresh rate to 100Hz while using HiDPi mode ?
i am using mac mini 2018, connected to SAMSUNG Ultra Wide Monitor by USB-C cable (also tried HDMI cable but no luck).
