Hi everyone,

While waiting for my 10.9 long screen, i tried to connect an old 7' screen from china to my Pi. ( Wiki )


i'v try with the config.txt params from WaveShare wiki, but it's not working.

Thanks in advance for your answers !

Hi, Fabian.

I don't have any WaveShare screens but I do have a non-touch 3.75" Kuman HDMI LCD screen in RPi designed to mount directly on an RPi (only to draw power via the GPIO) and with an HDMI jumper to the RPi. ATM, it's sitting on an RPi3B running moOde 7.6.1 (still!) and is working fine with the default config.txt settings.

What model Pi and what specifically does "not working" mean? Do you see anything on the screen when you turn power on? I see a Kuman splach screen then the typical Linux boot-up console output.

Kent

Hi kent,

Thank for your answer
My system is based on a Pi Zero 2 W with is own power
and the screen with is own power too
And betwen them, an HDMI2 cable (15cm long)

I can't see nothing on screen, only the backlight led are on and sometime to time a thin horizontal white line durant a short moment.
