Second Monitor

I installed a Radeon Pro W5500 to my dell computer and I have troubles to enable the second monitor.

I installed the drivers based on the Radeon website by running this command:
amdgpu-install

I am running gnome classic on a redhat 9.5 system the xorg version

and I added this configuration under this file:

/etc/X11/xorg.conf.d/20-amdgpu.conf

Section "OutputClass"
Identifier "AMD"
MatchDriver "amdgpu"
Driver "amdgpu"
EndSection

The 3D graphics are working and glxgears command I am able to see the gears running.

my xrandr command shows:
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 disconnected (normal left inverted right x axis y axis)
DisplayPort-2 disconnected (normal left inverted right x axis y axis)
DisplayPort-3 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 527mm x 296mm

I have connected a displayport on the DisplayPort-2 plug and I am unable to make the DisplayPort2 to show up as connected

Any ideas?
