After standby, display has to be reconnected before it's activated (Gnome Wayland)

Hi everyone,
basically my display setup looks like this:

But the Sony TV is mostly disabled, because i only use it when i want to watch movies/ series.

The problem that i have is, when i resume my pc from standby the display to the right (2) always stays black while the main monitor (3) wakes up correctly.
When i unplug the cable from the display and reconnect it, it wakes up again and works as expected, but this is very inconvenient.
I only have this problem since i have this third display on the left side, that i keep mostly disabled.

I am using Gnome/ Wayland with an AMD graphics card and use the normal mesa driver.

Every help is very appreciated!
