I'd read more reviews to see how it's done. I find some folk upset about how you have to use apps and the Chrome browser but what you want to do seems what the Chromecast does.
I have a Panasonic vierra LCD tv
It has 2 USB ports,2 HDMI ports,1 Ethernet port
My TV does not have a wifi
I would like to stream videos, music and photos from my laptop and iPhone
I have a router for wifi at home
If I buy a chromcast2 and fit it in the HDMI port of the TV
How will I be able to stream from my phone or laptop to the TV
