xrandr output through display port returns 'Configure crtc 4 failed'

Im trying to output to an external monitor through a type c port that allows display port through. This is on an asus g-14 and im trying to output to a Lenovo ThinkVision m14. On Windows on this same laptop it outputs correctly.

When I run xrandr I can see the monitor and it says that it is connected.

Running

 xrandr --output DP-1-0 --auto 

always returns

 xrandr: Configure crtc 4 failed 

The display link service is running during all of this

The wiki steps for seting this up describe using

 xrandr --setprovideroutputsource 1 0 

to create a DVI output that it all seems to be run through. When I run this command no DVI output is added to when running xrandr.

When running

 xrandr --listproviders 

I get

 Provider 0: id: 0x55 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 2 associated providers: 1 name:Unknown AMD Radeon GPU @ pci:0000:04:00.0
