The choice of method depends on your priorities:
- 🎬 Maximum quality (4K HDR, without delay) → HDMI-cable.
- 📶 Convenience and mobility → Miracast or Google Cast.
- 📁 Viewing uploaded movies without screen duplication → USB or DLNA.
- 🔄 Oldikovsky TVs (until 2018) → Chromecast or Mi Box S.
For owners of Xiaomi 12/13 series and Mi TV Q2/Q Pro, the best option is HDMI with an adapter: this guarantees 4K@60Hz with Dolby Vision support. If you have Redmi Note 10 and Mi TV 4S, Google Cast is optimal through YouTube Premium or Kodi.
