If the chromecast dongle is plugged into an HDMI port on the TV and its power cord is plugged into a USB port on the TV, can it stream content over a WiFi router if there is no other device such as a phone or tablet? Or is chromecast simply a way of displaying to the TV screen content that is being streamed to another device?
The TV does not have the Youtube TV app (too old).
