HP Recommended

I've tried connecting my laptop (auto setup to extent/share/mirror) to my HP all in 1 with an HDMI, but it wont show my laptop screen.

 

I've also setup a Targus doc, again using the HDMI and no luck seeing my laptop screen on the HP all in 1 screen. Targus and laptop all look good, is my HDMI port on HP all in 1 only for output? Or do I have to toggle/change a setting?

 

If helpful, both laptop and PC are bluetooth connected. My laptop has a USB-C/USB cord that I've tried to use instead of the HDMI but still no screen extension to the HP.

 

*update* i'm able to plug into a TV and see the mirrored screen just fine, so it must be the HP all in one HDMI. how can i fix? tyia

Thank you
