HDMI-Connectivity is the only way to get a latency of less than 20ms, critical for gaming. Wireless methods (Wi-Fi, Bluetooth) give a latency of 50 to 200ms.

2. Wireless screen duplication via Miracast (Wi-Fi Direct)

Miracast is the wireless screen transfer standard built into most Android 5.0 phones.+ Xiaomi TVs, the advantages of the method:

  • ๐Ÿ”„ No router required โ€“ the connection is established directly between the phone and TV.
  • ๐Ÿ“ถ Maintains permission until 1080p (Xiaomi 4S 55 above will not be possible).
  • ๐ŸŽ›๏ธ You can use it as a second screen (extended mode).

However, there are downsides: latency reaches 100-150 ms (unsuitable for dynamic games), and with a weak signal, video jerks are possible. If your phone and TV are connected to the same Wi-Fi network, you should use Google Cast (more on this below).

  1. On TV: Settings โ†’ Connection and sharing โ†’ Wireless display (Miracast) โ†’ Turn on.
  2. On the phone: open Settings โ†’ Connections โ†’ Wireless display (or Smart View on Samsung).

Why is Miracast slowing down?
Causes of video jerks at Miracast: 1. Wi-Fi channel overload - if there are many devices at 2.4 GHz nearby, switch the TV to 5 GHz in network settings. 2. Weak phone processor - budget models (Redmi) 9A, Poco M3) They canโ€™t handle real-time video encoding. 3. Low signal level โ€“ the distance between devices should be no more than 5 meters without obstacles. 4. Background processes โ€“ close all apps on the phone before connecting.

3. Broadcast via Google Cast (Chromecast) โ€“ for YouTube, Netflix, browser

If you want to stream content from specific apps (YouTube, Netflix, Google Photos), the best option is Google Cast. Unlike Miracast, it does not transfer the entire screen, but only content from the supported application, which reduces the load on the network.

Xiaomi Mi TV 4S 55 supports Chromecast built-in, but for that:

  1. The TV and phone must be connected to the same Wi-Fi network (required!).
  2. The TV must be enabled with Google Cast: Settings โ†’ Connection and sharing โ†’ Google Cast โ†’ Turn on.
