SOLVED: nVIDIA (HDMI) does NOT wakeup after long time

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?

Re: SOLVED: nVIDIA (HDMI) does NOT wakeup after long time

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.

Re: SOLVED: nVIDIA (HDMI) does NOT wakeup after long time

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.

I firmly believe that it is sufficient to define this value to correct the problem:

Option         "ConnectToAcpid" "False"

In any case, here's my config files for future reference:

I actually think this is the line that solved it for me... I tried ConnectToAcpid alone first and it didn't solve it for me.

Section "ServerFlags"
    Option "NoPM" "true"
EndSection
