Hello to everybody in this great community.
I am using an Minisforum HX90 (with AMD 5900hx) connected to smart TV (TCL C835) through HDMI.
I want the screen to dim (going almost black) when idle, in order to save power, but the dim option is missing under GNOME settings -> power
.
Is there any body who knows why is this happening?
Maybe it is an hardware related problem?
Following is the output of inxi -SGxxx
