Me being super jealous of everyone here going to 144 or 165 when I just upgraded my pc a few months ago to finally use 120 on my current ultrawide monitor.

All I can say is even 120 from 60 was amazing and very obvious. As someone else said the biggest wow moment was just moving desktop items around and it being super smooth.

I do know there are a bunch of settings you may need to change to make sure your using the correct settings above 60. Check the advanced display settings which should list out all resolutions with refresh rate to pick. Sometimes monitors need to be set. Sometimes the driver software for the GPU has options for it listed. I know on mine I had to have freesync enabled as well. Lots of variables that may keep it from being set correctly to check. I remember setting up my audio equipment and you think your using everything correctly then realize your advanced settings had an option set to like 44 bit rate instead of at least something more reasonable like 192.
