Can you elaborate on exactly what you mean?mmhorda wrote:Did anyone find a way to turn off LCD display while connected via HDMI with PINN?

I'm not sure where...Github, sourceforge and Raspberrypi forum are all quite open and the links are in my signature of every post I make.mmhorda wrote:This Manual must be published somewhere in a more open space
It is not PINN that is the problem as it is broken in NOOBS aswell. In fact it is the partition_setup.sh script that is written by OSMC that has become broken.mmhorda wrote:By the way OSMC is broken
I've done all the steps but the system stops at startup regardless of which display and regardless of the system (LibreElec, Volumio...)flowerdog wrote: ↑Wed Jun 08, 2016 9:11 pmHi guys,
the search is over. Here you will find an easy guide to autodetect hdmi on boot.
After following this guide you can use displays connected to hdmi, while the dsi display is connected.
If hdmi is connected on boot, it will use hdmi, otherwise it uses the integrated dsi display.
I have been searching the web already a whole day and know how painful and annoying it is.
So I share my solution:
I followed the guide on https://github.com/procount/pinn/blob/m ... ME_PINN.md . Scroll down there and you will find some instructions on autodetect hdmi. They are not so clear, so I write it more clearly down here.
I just tried it with rasbian, I don't know, if it works with other os
You need to use PINN and install rasbian with it, edit some files and then it works
In this instructions F:\ is the sd card
First of all:
1. Download PINN-Lite - https://sourceforge.net/projects/pinn/? ... p_redirect
- PINN is an extended NOOBS, which can detect hdmi on boot
2. Format your sd card with Formatter etc.- https://www.sdcard.org/downloads/formatter_4/
3. Copy the files from the PINN Lite zip file onto the formatted sd card
4. Download rasbian and copy it into the os-folder on the sd card e.g. F:\os\Rasbian
5. Mount sd card into raspberry pi and start installation
6. After Rasbarian starts and graphical user interface starts up, turn it off. Put the sd card back into windows computer.
7. Edit "recovery.cmdline" in F:\, add to the end of the line " dsi" , dont fortget the space-character, and save
8. Go to F:\ and create a config.txt and add the line "ignore_lcd=1" and save
- when starting, the output will be forced onto hdmi with this command. PINN menu will only be visible on hdmi source now
- this is important, so the dsi display does not blink, while using hdmi
9. Mount sd card back into raspberry pi and start into rasbian.
10.Open terminal and go to /boot/
11. Create file "config.dsi" in /boot/ - this config will be loaded, when hdmi is not connected
- dsi display loads automatically and does not need any commands, so the config.dsi can be empty
- you can add later, what usually would go into config.txt to configure your dsi display
12. Create file "config.hdmi" in /boot/ - this config will be loaded, when hdmi is connected
- add line "ignore_lcd=1" to config.hdmi, this forces to ignore the dsi display
13. Make sure all files are saved, reboot raspberry pi and READY !
It's working for me without any problems.
Thanks to ProCount PINN!
I am looking for another solution, to turn off the dsi display backlight, while using hdmi, but this solutions works well.
