Dual Screens TV/Touchscreen

Hello- these may be really Android 9 questions instead of hardware questions. Are dual screens possible? What I would like to do is use the TS050 touchscreen as a controller with my TV connected to the HDMI.
Is this an option? If I am connected to the MIPI-DSI port is the HDMI output still functional?

Yes, VIM3 support dual independent display via HDMI and MIPI-DSI.

Our team are working together with Amlogic to develop the dual independent display feature now, we will release new ROM to support this feature in the near future.

Good day!
