SOLVED M2 Studio Max 2nd monitor not 120hz from thunderbolt 4?

Hello!

I have just got a duplicate monitor to sit above my 1st one. The 1st monitor is from the HDMI and runs at 3008 x 1692 120hz just fine. The second is from Thunderbolt 4, but I can't get the 2nd monitor to run 120hz regardless of resolution.

I brought this cable: https://www.amazon.co.uk/UGREEN-Thunderbolt-Compatible-MacBook-Surface/dp/B0BXWBSJ77?th=1

Thank you in advance!

M2 Max, 32GB, OS15.5

I ended up chatting to Mac support. The M2 Studio doesn't support 120hz over Thunderbolt 4.

Gutted!
