Please be aware that touch functionality can only be facilitated through the Type-C CN2 interface when operating in HDMI mode. Secondly, once the correct connection is verified, it is advised to inspect the continuity and quality of the connections on the touch control board to ascertain their proper contact. Tonny12138
