Not detecting displays attached to AMD GPU

I have 2 gpus in my pc (rx570 and a 2080ti) but for some reason I can only see the monitors attached to my 2080ti - the AMD drivers appear to be loaded after checking 'lspci -k':

09:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev ef)
    Subsystem: Micro-Star International Co., Ltd. [MSI] Radeon RX 570 Armor 8G OC
    Kernel driver in use: amdgpu
    Kernel modules: amdgpu

not sure what else I can attach to assist in diagnosing this but please let me know if theres anything I can try / provide an output for.

Thanks!

Re: Not detecting displays attached to AMD GPU

I can only see the monitors attached to my 2080ti

Shuffle the other ones into the front position?
…
"See" where?
What's the output of "xrandr -q; xrandr --listproviders"?
Also post your xorg log, https://wiki.archlinux.org/title/Xorg#General and your system journal ("sudo journalctl -b", just that the module is loaded doesn't mean it has no troubles)
