Oct 6, 2018
I have one old Samsung LED TV ( UA40J5100AR ), I like to use the same with Smart TV function, In this case if i inject Chromcast, it will work? Please advice.

Chromecast does not convert a regular TV in to a Smart TV, not at all.

It simply allows you to stream video from a WiFi enabled laptop or PC to a regular TV. The TV must have an HDMI input port to plug the Chromecast device in to.
Chromecast does more than just allow you to stream from your phone.
Alternatives include Apple TV, Roku, Amazon Fire, and Android TV boxes. I would suggest you figure out what streams you want to watch and make sure that the device you choose will work with them. From the viewpoint of greatest flexibility the Roku and Android are probably the best. The Roku is easier to set up than the Android.
