Re: PI3D - specify the HDMI port to use

Ran fine the whole day.
Only the transition looks a little jerky, especially when both instances doing it at the same time, but can't see any memory or cpu peaks.

Might be an idea to change the code to use single pi3d instance and 2 sprites or something..

Re: PI3D - specify the HDMI port to use

Creating the pi3d window on the second screen works just fine with: DISPLAY = pi3d.Display.create(x=1920, y=0, w=1920, h=1080, .. Might be off topic now but is there a way to disable the screen spanning having 2 screens (:0.0, :0.1) with 1920x1080 instead of 1 screen with 3840x1080? Thanks, Sven

Any other hint to get access to the screens individually in Xorg by 0.0 and 0.1?

Re: PI3D - specify the HDMI port to use

Hey Paddy, thank you for guiding me into the right direction. To get both displays running I can't use 'dtoverlay=vc4-fkms-v3d'. But having this commented out vc4 module isn't loaded. I loaded it by hand and all of a sudden everything just works fine. To sum things up: config.txt [pi4] # dtoverlay=v...

Re: PI3D - specify the HDMI port to use

Hi all, I ran into the same problem trying to get PictureFrame running on a Pi4 using both HDMI outputs. To sum up what I did. in /boot/config: #dtoverlay=vc4-fkms-v3d max_framebuffers=2 So I got /dev/fb0 and /dev/fb1 seperate allowing Xorg to create 2 screens. In my case left display is ":0.0" and ...
