Hi, after a fresh installation of CachyOS (KDE Wayland) on my laptop (Lenovo Legion 5 15IAH7H), I cannot get my external monitor to work when connecting it to the HDMI port. The monitor wakes up briefly, but the screen remains black before turning off again.
I partially resolved the issue by changing the UEFI settings to use only the dedicated GPU. However, this is not an optimal solution, and I was also unable to change the screen resolution on my laptop afterward.

Moreover sometimes the system hangs during the boot but restaring it solves the issue. Logs:
