I totally get where you’re coming from. Low latency is crucial, especially when you’re gaming or watching fast-paced videos. From my experience, one of the best ways to get a seamless mirroring experience is to choose an app specifically optimized for this purpose. I’ve tried a bunch, and I found that many free options can be quite laggy. However, there are premium ones that are much better.

One of the top picks I’d recommend is actually highlighted in this guide I found. It’s specifically about the best screen mirroring app for iPhone, which you can check out here. The guide reviews several apps, including ones like Reflector and ApowerMirror, and even discusses some lesser-known but effective ones like Eltima’s JustStream. This app, in particular, offers solid performance with very low latency and works well with Chromecast too, so you don’t have to deal with lag. I personally use it to cast iPhone photos to TV without issues, and it makes everything look much smoother compared to others. Give it a try; it might solve your problem!
