Monitor Samsung P2470H at home
-
Ok, i posted in the thread, lets see the progress.
Another thing is, my monitor has a touchpad connected with flat wire to the frame
I am just wondering how the raspi could even switch the monitor on or how i will control the Magic Mirror ;) -
@fox maybe you can hack the soft buttons, and emulate them with the pi over gpio pins, write some code …

Good idea this could work. Even when the brightness / contrast is adjusted i need only P_ON/OFF, and i can put a signal on the GPIO Pin when the raspi boots, soldered parallel on the wire.
Thx for this idea! -
Remember, the pi GPIOs can only handle 3V3. Check the voltage of the monitor buttons with a multimeter before soldering. You will likely need a level shifter.

I have disassembled the monitor and have seen that I can’t give the signals per gpio.
It’s a serial connection and I can’t simulate the protocol.
So, is it possible to use the LCD Screen?
It’s a m240hw01 v2 -
@fox It’s possible. If you configure your Pi to turn off the signal to the HDMI port, the monitor should shut off automatically. It should remain off until it detects a signal again, whereupon it will turn itself back on.
The MotionDetection module can do this for you with a Raspberry Pi camera. Otherwise, there is a module for using a PIR sensor.
