The USB-C port of the Lenovo Tab P12 supports data transfer and charging, but there is no specific information on whether it is suitable for displaying on a TV or projector via an adapter. Normally, mirroring the display on a TV or projector requires a function such as USB-C with DisplayPort Alt Mode or HDMI adapter, which is not explicitly mentioned in the product profile. It might be helpful to test an adapter that converts USB-C to HDMI to see if this works.
