Display off on idle

Hi everyone,

I have my KODI - libreelec build (x86 intel) linux build going into the TV via a HDMI switcher. In kodi I noticed that the software can and does stop the signal after a set period of time of inactivity. I was wondering if it was possible to completely disable the HDMI ie depower the cable and then renable when required. This is required so that the switcher switches over - the lack of a HDMI signal does not be sufficient but the absence or presence of the power (from other devices) seems to be trigger.

I am a relatively inexperienced in linux so any help would be appreciated.

thanks

thanks for the reply, though i think i have not explained clearly enough. the switcher needs the hdmi cable to power off in order to switch to the next device. the lack of a signal is not enough. :)...ie putting kodi to suspend the machine works..but i required the machine to be running to access smb shares.

thanks again
