Anyone know what kind of adapter is needed to convert spectrum [View all]

Cable coming out if the wall to an hdmi ? I’m guessing there is an adapter. What do you call the kind of cable- sdi or coaxial or ?

I’d like to bypass the cable box and save 80$ A year. Replacing it w my old Mac mini.

I’d get rid of the rented modem too if I could figure out how.

I’m all ears on all points.

Spectrum serves up internet, WiFi and tv. (Nobody asked but all I watch is MSNBC, PBS Hawaii and TCM.)

Thanks!
