How to connect a Xiaomi device to a TV via HDMI: 4 proven ways

Connecting Xiaomi devices to a TV via HDMI opens up new possibilities for viewing content on the big screen, from streaming videos to games from mobile devices. However, not everyone knows that there are several methods for this, from direct cable to wireless technologies. In this article, we will discuss all the current ways of connecting, including the nuances for different models of smartphones (Redmi Note 12, POCO X5, Mi 11) and set-top boxes (Mi Box S, Mi TV Stick).

The main problem that users face is the incompatibility of connectors: modern Xiaomi smartphones are devoid of classic HDMI-TVs rarely support live broadcasting USB-C. The solution depends on your device model and the adapters available, and we will take a closer look at each option so you can choose the best way to do it without spending too much on unnecessary hardware.

1. Direct connection via HDMI-adapter (for smartphones and tablets)

The most reliable way to display an image from Xiaomi to a TV is to use a USB-C adapter to HDMI.This method works for most current models that support DisplayPort Alt Mode (including the Mi 10/11/12, Redmi K50, POCO F4). The main advantage is minimal signal delay (ideal for gaming) and maximum resolution up to 4K@60Hz.

To connect you will need:

• 🔌 adapter USB-C → HDMI (We recommend original from Xiaomi or certified Anker, Baseus)
• 📺 HDMI-cable (version 2.0 or higher for support) 4K)
• ⚡ Power supply (charger) 18W+) — Some adapters require additional power.

Step-by-step:

1. Connect the adapter to the USB-C port of the smartphone.
2. Connect the adapter to the TV through HDMI-cable.
3. Connect the charger to the USB-C port of the adapter (if required).
4. On your TV, select the HDMI signal source (usually the Source or Input button on the remote).
5. On the smartphone will appear a notification about the connection to the external display – confirm the resolution.

Important nuance: On some models (Redmi 9, POCO M3), the DisplayPort Alt Mode function can be disabled by default. To activate it, go to Settings → Connected Devices → HDMI and turn on the option Output to an external display.

⚠️ Warning: If the image on the TV is missing or flickering, try another one HDMI-cable (not all cables support video transmission) and check if the adapter is overheating, which may indicate a power shortage.

2. Connect via MHL (for older Xiaomi models)

MHL (Mobile High-Definition Link) technology was used in Xiaomi smartphones until 2018 (e.g. Mi 5, Redmi Note 4, Mi Max 2) and allows video and sound to be transmitted over a Micro-USB port, but requires a special adapter and support from the TV.

The features of MHL:

• ⚡ Requires external power supply (adapter connects to the outlet)
• 📶 Maximum authorization — 1080p@30Hz (no support) 4K)
• 🔄 Not all TVs support MHL (Check for the presence of the logo MHL on HDMI-port)

Instructions for connection:

1. Buy it. MHL-Adapter for Xiaomi (for example, the original Xiaomi) MHL Adapter or universal from Samsung).
2. Connect the adapter to the Micro-USB port of the smartphone.
3. Connect the adapter to the TV through HDMI-cable.
4. Connect the adapter to the power source (required!).
5. On the TV, select the appropriate HDMI-port.

MHL-Adapters are outdated and almost never available for new models. If your smartphone is released after 2018, this method will not work. USB-C → HDMI wireless.

3. Wireless connection via Miracast (without cables)

If you don’t want to mess around with wires, Miracast is the perfect solution for streaming Xiaomi’s screen to a TV, a point-to-point technology (without a router) supported by most modern TVs (since 2013) and Xiaomi’s Android 5.0+ smartphones.

1. Make sure your TV supports Miracast (see Screen Mirroring, Wi-Fi Direct, or AllShare Cast options on the menu).
2. On a Xiaomi smartphone, open Settings → Connection and Sharing → Screen Broadcast.
3. Turn on device search and select your TV from the list.
4. Confirm the connection on the TV (entry may be required) PIN-code).

Important nuances:

• 🔋 Miracast broadcast severely drains the battery - keep your smartphone on charge.
• 📶 Image delay can reach 50-100 MS (not suitable for competitive gaming).
• 🔊 Not all apps support audio broadcasting (for example, Netflix can block output via Miracast).

💡

If Miracast doesn’t find the TV, restart both devices and check if Wi-Fi Direct is enabled in your TV settings.

4. Connect via Xiaomi TV set-top box (Mi Box, Mi TV Stick)

If you have a Xiaomi Mi Box S or Mi TV Stick, you can use it as a middleman to display images from your smartphone, a method that is convenient because it does not require additional adapters and provides a stable connection.

3. On your smartphone, open Settings → Connection and Sharing → Screen Broadcast.
4. Select your Mi Box from the list of devices.
5. Confirm the connection on the TV.

Comparison with Miracast:

For gaming purposes, we recommend using the Steam Link or Moonlight app (for streaming games from PCs).The Mi Box S supports these apps and provides a latency of less than 30 ms with a good Wi-Fi connection.

5. USB connection (for MHL/USB-OTG TV support)

Some TVs (such as Samsung or LG models from 2015-2017) support connecting smartphones via a USB port using USB-OTG technology. This method is less common, but can help if other methods are not available.

What you need:

• 🔌 Cable USB-OTG (with a micro-USB or USB-C on the smartphone side and USB-A TV-side)

Limitations of the method:

• 📵 It only works on older TVs (newer TVs don’t usually support this mode).
• 🔋 Requires external power for the smartphone (the battery is discharged very quickly).
• 🖼️ Often only images are transmitted without sound.

⚠️ Note: When connecting through USB Some Xiaomi smartphones can go into charging mode instead of video transfer, in which case try using an externally powered adapter or choose another method of connecting.
