1. Miracast: A universal standard for Android and Windows
Miracast — is a screen mirroring technology that works without the internet, creating a direct connection between your smartphone and TV. It's built into most Android-devices starting from version 4.2 and is supported by TVs Samsung (Smart View), LG (Screen Share), Sony (Miracast) and others.
The main advantage is minimal delay (10–50 ms), which is critical for games or video calls. However, image quality depends on the power of the smartphone's processor: on budget models (Redmi 9A, Samsung Galaxy A12) there may be some lag when resolving 1080p.
