The HDMI port on the card is 1.3 which means it should be able to do 120Hz at 1080p to which I'm wondering if your driver needs reinstalling, after using DDU in Safe Mode, then using the latest GPU driver sourced from Nvidia's support site in an elevated command.

Have you gone into Nvidia's Control Panel and seen if you can manipulate the refresh rate for your monitor(left hand navigation pane, Display>Resolution)?
 
Unlikely that it supports 75 Hz at 1080p. Generally 75 Hz is only supported on some older CRT formats like 1024×576 or something like that. This is only included for legacy compatibility.


1080p with standard CTA timing (2200×1125) at 75 Hz already gives horizontal frequency of 1125 × 75 Hz = 84.4 kHz which is outside the range given in the monitor's online datasheet (82 kHz max). So this 75 Hz would only be available at lower resolutions. Of course, you can always try setting custom resolutions to drive it outside its rated range, but there's no guarantees.
