How can a touch screen and TV screen be enabled together?

The touch screen Raspberry Pi 4 works wonderfully but in the HDMI port on the TV I do not see the volumio but I do hear the music.
So how do I also enable the TV screen to be seen?

here you find all screen settings… otherwise @gvolt knows a lot about settings…

can you help me on this?

Need some time to investigate, can’t promise anything :wink:

Thanks, hope you find a solution

Do you mean to conect the both hdmi outputs or one hdmi and one dsi output?

one hdmi and one dsi output

Exactly also my case, I am also interested :).

Hey, is there any good news?
