Why Do You Have to Duplication Screens on Xiaomi? TV It is unstable and how to fix it

Duplication of screen on Xiaomi TVs (series Mi) TV A Pro, Mi TV Q2, Redmi Smart TV Others) should be a simple process, but in practice users are faced with image delays, connection breaks or a complete lack of signal. The reason often lies not in the TV itself, but incompatibility of wireless transmission protocols, outdated source device drivers, or incorrect network settings.

In this article, we will analyze all the current methods of duplication - from the classical to the traditional. HDMI-We will provide cables to Miracast, AirPlay and Wi-Fi Direct wireless technologies, as well as checklists for diagnosing problems. TV, which the manufacturer does not advertise in official instructions, for example, the forced inclusion of compatibility mode for old smartphones.

If you've already tried to connect and you get an error like "Device not supported" or "Can't connect to the screen" - don't be quick to blame the technology. 80% of the time, the problem is solved by changing one or two parameters, which we will discuss below.

1. Preparing Xiaomi TV for screen duplication

Before you try to connect a phone, laptop or PC, you need to make sure that the Xiaomi TV itself is ready to receive the signal, and many users miss this step, which causes connection errors.

The first thing to do is to update the TV firmware, and older versions often don't support modern wireless protocols (such as Miracast 3.0 or AirPlay 2).

Settings → About TV → System Update

The second is to enable Wireless Display (or Screen Mirroring in English) and the path to setup depends on the model:

• 📺 Mi TV A Pro / Q2 / P1: Settings → Connections → Wireless display
• 📺 Redmi Smart TV: Settings → Devices → Wireless projection
• 📺 Old models (2019-2021): Settings → Network settings → Miracast

⚠️ Note: On Xiaomi TVs with firmware below MIUI TV 3.0 Miracast can be hidden. To activate it, go to Settings → For developers and enable the option "Show hidden functions".

The third step is to check Wi-Fi mode. The TV and the source device (smartphone, laptop) must be connected to the same network at 5 GHz (for minimal delays).If your router only runs at 2.4 GHz, duplication will be possible, but with noticeable lags.

Duplicating the screen by HDMI: reliable, but with nuance

The most stable way to transmit images is through cable. HDMI. It guarantees minimal latency (important for gaming) and supports resolution up to 4K@60Hz. But even here, there are pitfalls.

The connection will require:

• 🔌 Cable HDMI 2.0 or later (for 4K necessarily HDMI 2.1).
• 📱 Adapter for a smartphone (for example, USB-C → HDMI For modern Xiaomi, Samsung, iPhone).

Instructions for connection:

1. Put the cable in the port. HDMI on the TV (it is advisable to use a port marked with a note) ARC or HDMI 2.1 for better compatibility).
2. Connect the second end of the cable to the adapter and the adapter to the source device.
3. On the TV, select the appropriate signal source (Source or Input button on the remote).
4. On a smartphone or laptop, you may need to turn on the “Duplicate screen” or “Expand screen” mode (in the display settings).

⚠️ Note: If the image does not appear, check it out: 🔄 Whether the cable (ports) is flipped HDMI on some Xiaomi models TV connector-sensitive). 🔋 Is the adapter powered enough (some cheap adapters require additional power) USB-feed-in). 📺 Is the TV on? HDMI-CEC (Settings menu → HDMI). This will allow you to control the TV from the smartphone remote.

For gamers: if you connect Xiaomi TV PC-to-consolidator (PS5, Xbox, in the settings of the TV, turn on the "Game" mode (Settings) → Picture → Image mode → This will reduce the input delay to 10-15 ms.
