USB/HDMI touch displays and VIM3

VIM3
1

How is the touch screen support (other than TS050) on VIM3 + Android 9? Are most HDMI+USB touch screens plug and play? I have seen some other topics on VIM1 or VIM2 but I want to make sure I am getting the most up-to-date information.

Thanks in advance!

Yes, HDMI Screen + USB HID touch panel comes available for any Khadas SBC.

Be note that the touch panel driver might required to support the model you used.

Have fun!

Hi @Gouwa, thanks for the response…my question, then, is really which touch display HIDs are known to work in Android 9 out-of-the-box, i.e. without requiring driver porting or development.
Kind regards!
