Issues with Triple (3) monitors set up

Hello, i'm a new user and i want to join Garuda community

So my issue here is with my setup which has 3 monitors, 2 display ports and 1 HDMI
I have an AMD 6800XT (output 3 DP & 1 HDMI) and AMD CPU 3900x
I made the bootable USB with Garuda Kde gaming edition and booted from it, so it loads the kernel from the USB at the beginning and all 3 screens are in mirror mode which is fine and shows that they work properly
Next it loads Garuda and i can see that the three monitors are like extended because i can take one window and drag it along from monitor 1 to 3 properly.
Here is where the issue starts the installer won't launch with this specific monitor that i have on hdmi (monitor 3), i can install garuda with my 2 monitors or 1
After i installed garuda with 1 monitor and the system works properly i put the 2nd monitor and works fine but the 3rd monitor doesnt get image, i can see the 3rd monitor on arander
The autorandr service seems to be rearranging the primary monitor.

Even though I fixed the primary monitor via cli xrandr I cant seem to be able to enable the HDMI 3rd monitor by trying many xrandr commands

anyone has any similar issue or advice on the specifics of xrands

Glad you figured it out. I wouldn't exactly call it "insane" though, because I just saw a multiple monitor issue the other day the with the same solution --- which was to change out cables. :smile:
