I can’t connect the video airplay from my iPhone 12 to my lg smart tv

Hello,

I have used this brand of apps for my Samsung TV, as well as my windows PC. Please note that there might be limitations, like extreme delay or not being able to stream some apps.

your other option would be to invest in a lightning to HDMI adapter. This is an official Apple one which I highly recommend, but I know it is pricey. It is pretty easy to find other options on Amazon or eBay. Personally, I recommend this over the app as it is great for traveling and is completely universal with anything that supports HDMI input as well as being able to stream all content without restrictions. The only downside is that it is wired, so you would have to buy a long HDMI cable in addition to the adapter.
