2. Network congestion — torrents, online games, or 4K streaming are running simultaneously.
3. Old TV - some models LG/Samsung 2012–2015 only support Miracast at 720p resolution.
4. Incompatible codecs - for example, video in format HEVC (H.265) may not be transferable without conversion.
⚠️ Attention: On iPhone And iPad instead of Miracast is used AirPlayIt needs to work Apple TV or a TV with support AirPlay 2 (Samsung 2018+ LG (2019+).
