When I put the computer to sleep or if the display turns off due to KDE/OS power settings my 1st and 2nd monitor come back no problem, but my 3rd monitor does not. It remains a black screen. I’ve tried using the KDE Display Config to enable/disable, change refresh rate, etc. and some times that works, but most often it does not. The only way to get it to come back is by shutting down. Unplugging all the external monitor cables to my Razer Blade 16 2023, then boot into the O/S on my built in monitor and then re-connect the external monitors. For reference I have (1) hdmi plugged in and then (2) plugged into a Thunderbolt 4 dock via DP to ThunderBolt which one of those is the 3rd monitor.
