How to enable the Inland 3.5" TFT LCD Touchscreen Monitor on a Raspberry Pi-3B works.

How do you switch back to the HDMI output? What driver needs to be swapped where?

Thanks for any clues offered.

I found this on the Raspberry Pi forums, perhaps it will help you for your question.

From: https://forums.raspberrypi.com/viewtopic.php?t=256237

To Switch from LCD Display to HDMI monitor :

cd LCD-show
sudo ./LCD-hdmi

reboot and your LCD screen becomes disabled, unplug it from raspberry and plug in your external HDMI monitor .

2. To Switch from HDMI monitor back to LCD Display :

cd LCD-show
sudo ./MPI3508-show

( where you select your model of LCD , MPI3508 in my case)

reboot the Raspberry Pi , the HDMI monitor becomes black and your LCD display is active again.

Right... That's what I did... It works... Now I can't use the HDMI anymore, just the 3.5" LCD. HOW do I switch it back and forth between LCD & HDMI?

THANK YOU!

IT WORKS. Makes it much easier to continue development, OBTW: I didn't need the "sudo" to do it on mine.

It looks like a common source, even the silkscreen looks the same.
