Does screen mirroring use Wi-Fi or Bluetooth?

Okay, so, you're wondering if screen mirroring uses Wi-Fi or Bluetooth, right? It's mostly Wi-Fi. Think about it – Bluetooth, while wireless, is kinda slow for something like video, isn't it? I mean, imagine trying to watch a movie mirrored from your phone and it's all laggy and pixelated... nightmare! Wi-Fi just has that bandwidth you need for a decent picture. It's way faster and more reliable for streaming that whole screen.

I remember trying to connect my phone to my TV once with Bluetooth, thinking I was so smart, you know? Total fail. It could technically kinda sorta do it, but the lag was insane! So yeah, for a smooth, high-quality experience, Wi-Fi is definitely the way to go. Or, you could use a wired connection, I guess, but who wants to mess with wires these days? So, yeah, Wi-Fi’s your best bet for sure.
