how to connect lg g flex to vizio tv

I want to view pictures from my phone on my smart vizio tv via wifi. When I ask the phone to connect to a wi fi device it says no devices available. Same with my tv. How do I populate devices to select like my computer and phone on my vizio tv? I'm so confused. Do I need to download an app to my lg phone? Or an app to my vizio tv? If I can't do it wirelessly, how do I do it with a wire? The Hdmi cable that came with my phone doesn't fit in the tv.
