Controlling HDMI or vga monitor Answered
I'm working on a project that I need a monitor to display information for a predetermined amount of time then turn off (Im will not be using the Raspberry Pi for this). In a days time I may want the monitor ON/OFF twice or several times. I've got experience with using relays, and was thinking of breaking the 110v to achieve it, however not sure if I would be shorting the life of the monitor by doing this. Would it be more practical to break the incoming HDMI cable with some particular pinouts( like the video or signal or 5v? with a relay or two) and keep the monitor turned on 24/7? Thanks! FYI. This monitor will NOT be connected to a PC, it will only be displaying my outside cameras when activated.
