Enable/Disable video output

[ebolisa]

Hi,

My MM is connected 24 hrs showing some data and streaming a web with video and music content.

Because of that, I’m using a script to turn HDMI off at night and turn it back on in the morning.

When the monitor turns back on, it doesn’t show video, just sound. Checking the web page, everything is displayed fine, sound included.

I’m using the following cmds to turn on/off the monitor and they work but, as I said, there’s a wake-up issue:

vcgencmd display_power 0 > /dev/null

or

/opt/vc/bin/tvservice -o

Is there a way to refresh the video output through MM or, better yet, enable/desable it via a schedule?
TIA

Solved by issuing a npm restart.
