VR locked at monitor refresh rate

[TG29]

As the title states the refresh rate of my Valve Index headset is locked at the refresh rate of my monitor (projector in this case), which is 1920x1080 @ 60hz.

In Content Manager and in AMD Software I have vsync disabled and SteamVR is set to 120hz.

My pc: 5800x3d, 7800xt and 32gb 4000mhz. Now I get steady 60 fps with a lot of headroom left.

In Content Manager the resolution is set to my projector's 1920x1080 @ 60 hz. How do I get around this so I can have a higher refresh rate in-game?

Your help would be greatly appreciated, thanks!

Changing the refresh rate of the Index to 144hz in SteamVR unlocked the fps in-game. In Content Manager I could see that my fps was just over 120 fps. I then changed the refresh rate in SteamVR back to 120hz (what it was before), and the fps was still a nice steady 120. Problem solved then I guess, but still not sure what was causing it since it's now back at the same setting it was before. Haven't changed any other settings..

I spoke too soon unfortunately. After restarting SteamVR it's back to 60 fps and changing the refresh rate to 144hz doens't do anything this time.. Any ideas?
