I’m trying to hook up my spare laptop running Manjaro KDE to my living room tv. It’s an older Toshiba satellite amd-a6. When I plug it into the avr or tv directly via hdmi, display manager sees it but nothing displays on the tv. I tried with Linux Mint and its working fine, same with my other laptop running Win10.
Can be anything

So it seems to work when I have the laptop lid closed and only the tv on. Its a 4k tv but i use 1080p but it only allows 30fps. On mint I was able to use 120hz.
As you can see in the dispay section it says that it failes to load you display driver

I guess your running with amdgpu now but I think you need to set a few thing to get it in its best.
Since it is a sea island classified card I think you could modify the kernel parameters in the kernel command line as.
radeon.cik_support=0 amdgpu.cik_support=1
This way you force the amdgpu drivers to load.
The way to do that is open /etc/default/grub
with your favorite editor with sudo.
For instance:
sudo vim /etc/default/grub
find the line that starts with
GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3"
modify it to
GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.cik_support=0 amdgpu.cik_support=1 udev.log_priority=3"
safe the new config en rebuild grub with
sudo grub-mkconfig -o /boot/grub/grub.cfg
reboot
check how it goes now
Note: It can be you also need to tune some xorg settings.
