Second monitor not working at max refresh rate after NVIDIA update

I’m using an Acer SB220Q monitor in a dual monitor setup.
It has a max refresh rate of 74.97 hz.
I recently upgraded my nvidia version.
After restarting, it displayed the message ‘input not supported’.
I lowered the refresh rate to 60 hz and it started displaying stuff again.

You are currently running the v515 beta driver, does the 510 driver still work?
