Monitor refresh rate

[Jonr515]

I recently purchased a Samsung S65UA 34' ultra wide monitor for my M1 MBP, the monitor is capable of 100hz refresh and was running that when I first used it. Now only 60 hz and variables 48-60 are available in the menu. It is directly connected via USBC. Any suggestions on how to get more resolution options?

USB-C to what port on monitor? Has there been any updates to your monitor recently?
