Hello folks,
I would like to use the new Raspberry Pi for nanondlp.
Is it possible to use one HDMI output as "projector" and the other as normal display to show the user interface?
Thank you so much for your help and nice weekend.

I am also interested on this, I added to pi3 a 7" raspberry dislpay, but I also have to use another pi3 for nanodlp. Then in a printer I have 2 raspberry
I am looking for a solution to use those 2 hdmi pi4 ports one for printing shield and one to show the nanodlp web interface
Anyone did it, or working on it??

As I remember somebody on the forum have done it using xserver. Not sure about thread.

Thank you, problem solved.
It was possible to do it also with pi3 using lcd bus and hdmi to control touch screen lcd and shutter board
But pi4 is more powerful

I'm trying to do the same with Raspberry Pi 4 and a projector connected to hdmi1 on Raspberry. How did you manage it?
Thanks!

Update: I'am able to manage the projector in the right way if I connect only it to hdmi0 on raspberry. So I was thinking to use xserver to run a user interface on touchscreen connected on raspberry's hdmi1. If I connect the touchscreen the projector is not working properly, from projector calibration page the only thing I'm just sometimes able to see are boundaries for 1-2 seconds. I tried to enable hdmi_safe=1 and config_hdmi_boost=4 in /boot/config.txt but no changes.
Does anybody have any suggestion please? Thanks!
