I have GTX1660S and KDE. Using latest nvidia and linux.
As in title, it happens (almost) always when I let my PC in idle (not suspended) over night and also when is in idle for about some hours (let's say 4 hours).
When I turn on the TV, I get no signal (even if I press keys in the keyboard).
Tested with both SDDM lockscreen enabled and disabled.
Tested with both leaving the TV turned on and also turning it off.
I can wake-up the GPU with these two workarounds:
Suspend the PC using keycombo in my keyboard and then resume from suspension
or
Login via ssh and then change resolution with xrandr
$ export DISPLAY=:0
$ xrandr --output HDMI-0 --mode 1920x1080 --rate 60 && xrandr --output HDMI-0 --mode 3840x2160 --rate 60
Is the only way to completely disable DMPS?
Must I have a xorg.conf file to set it off?
$ xset q

d.ALT, same problem here: I have 2 monitors connected to the card.
DVI Monitor recover from sleep OK
HDMI Monitor will not recover from suspend, ALT+CTR+F2 and the ALT+CTRL+F1 will recover HDMI monitor.

This DOES NOT solve the problem:
$ cat /etc/X11/xorg.conf.d/10-monitor.conf
Section "Extensions"
Option "DPMS" "Disable"
EndSection
Any other ideas?

I replaced HDMI cable with DisplaPort and now is working OK.
