With supported reference platforms, touch panels are not used yet, it’s just a HDMI display. Did you flash Celadon on your tablet? If yes, please provide more details (processor, make etc).


You can file this as a request for Celadon here.

Subject: [01.org Celadon] bout the error between tablet and external penal(celadon android O)


I have a tablet with a touch penal and hdmi external output.

When I only use the touch panel, everything is fine


But when I plug in the external hdmi panel, the hdmi panel can't be displayed,

and the touch function will be wrong (do not match the touch panel)


I think the error is in android.hardware.graphics.composer

This error did not occur in android x86 oreo (Not imported android.hardware.graphics.composer)


My touch panel information

Resolution: 800x1280

Interface type: mipi

Touch type: capacitor
