How to connect a 24-inch TV to Xiaomi devices: all ways + error solving

Connecting a 24-inch TV to Xiaomi’s ecosystem opens up access to advanced Smart TV features, mobile streaming and smart home integration. However, not everyone knows that how to connect depends not only on the TV model (such as the Mi TV 4A 24 or Redmi Smart Fire TV 24), but also on the type of Xiaomi device you work with: a smartphone (Redmi Note 12, POCO X5), a console (Mi Box S), a router (Xiaomi Router 4A) or even a laptop (Mi Notebook).

In this article, we will analyze all current ways of connecting, taking into account the features of the protocols. HDMI 2.0, Miracast, DLNA Bluetooth 5.0 and the typical synchronization errors, and we'll focus on the audio setting (if you don't have a connection). HDMI-And you can use the Mi Game Controller to optimize your image latency, and if your TV isn't detected by the system, or if you have artifacts on the screen, at the end of this article, you'll find a table of solutions for 90% of the time.

1. TV Preparation: Port and firmware checks

Before connecting, make sure your 24-inch TV supports the connection method you choose. Most Xiaomi models (such as the Mi TV 4S 24" or Redmi Smart TV X24) are equipped with:

• 🔌 1–2 port HDMI (usually HDMI 2.0 supportive 4K@60Hz, but 24" models are often limited 1080p)
• 📶 Wi-Fi 5 (802.11ac) Bluetooth 4.2/5.0 (for wireless headphones and keyboards)
• 🔄 USB 2.0 (for firmware or media playback)
• 🎵 Optical output (if you need external sound)

Critically check the firmware version: outdated software may not support Miracast or Google Cast. Update your TV via:

1. Go to Settings → About TV → System Update.
2. If there are no updates, download the latest firmware for your model from the official Xiaomi website and install via USB.

💡

If the TV doesn’t find updates over Wi-Fi, connect it to the network via an Ethernet cable (if you have an RJ-45 port) or use a mobile hotspot on a Xiaomi smartphone to download files.

⚠️ Note: Xiaomi TVs with firmware older than 2022 may not support Wi-Fi Direct. In this case, a Xiaomi router with Mi Mesh function will be required for wireless connection.

2. Connection via HDMI: Smartphone, console or PC

HDMI is the most stable way to connect, providing minimal latency and maximum picture quality, but there are nuances on 24-inch TVs:

• 📱 Xiaomi Smartphone: You will need an adapter USB-C → HDMI (for example, Xiaomi USB-C to HDMI Adapter. Supports models with USB 3.1 (e.g. Xiaomi) 12T, Redmi K50).
• 🎮 The Mi Box console S/Mi TV Stick: Connects directly to the port HDMI. Use the original power unit for power supply (5V/2A).
• 💻 Xiaomi laptop: via cable HDMI-HDMI or USB-C → HDMI (if there is no port HDMI).

Step-by-step instructions for a smartphone:

Enable USB Debugging and Image Transfer to Settings → About Phone → MIUI Version (7 times click on version)

Connect the adapter to the smartphone, then HDMI-cable

Select the HDMI 1/2 signal source on TV

3. Wireless connectivity: Miracast, Google Cast and DLNA

If wires aren't an option, use wireless protocols, which are available on Xiaomi's 24-inch TVs:

How to turn Miracast on Xiaomi TV:

1. Open Settings → Connection and Sharing → Wireless display.
2. Activate Miracast.
3. On your smartphone (MIUI 12/13/14), go to Settings → Connect and Sharing → Transfer to the screen and select your TV.

Important: On Xiaomi TVs with firmware below 2021, Miracast can only run in 720p mode.Update the software to support 1080p.

⚠️ Note: When using Google Cast via Xiaomi router, disable the Smart Band Steering feature in Wi-Fi settings – it can cause connection breaks when transmitting video.

4.Sound Connection: Bluetooth, Optical Output and HDMI ARC

If you've connected your TV to HDMI, but the sound is coming through your smartphone or console speakers, you need to redirect the audio stream. On 24-inch Xiaomi models, you can find options:

• 🔊 HDMI ARC: It allows you to transmit sound from the TV to the soundbar or receiver. TV 4S 24" and later. Included in Settings. → Sound. → HDMI ARC.
• 🎧 Bluetooth: to connect headphones or speakers. Go to Settings → Bluetooth and select the device.
• 💿 Optical output: for external audio systems (e.g. Xiaomi Mi Soundbar) TOSLINK.

If there is no sound through HDMI:

1. Check that the cable supports ARC (there should be a sign on the connector).
2. On the TV in Settings → Sound → HDMI output, select PCM or Auto.
3. On your smartphone in the sound settings (Settings → Sound and vibration → Sound quality) turn off Higher quality (Hi-Res).

For games using the Mi Box S or smartphone, always use HDMI + external speakers/earphones over Bluetooth. Built-in speakers of 24-inch TVs do not provide enough volume for immersive sound.

5. Connecting to Xiaomi router: setting up a network for streaming

For stable operation of Google Cast, DLNA or online games through Mi Box, it is important to properly configure the router. 4A/AX3600:

• 📡 Wi-Fi range: Use 5 GHz (less interference but less range).
• 🔒 Encryption: WPA2-PSK (not WPA3, Some of the older TVs don’t support it).
• 🔄 Channel: manually select the channel with the minimum load (for example, 36 or 149).
• 🚀 QoS: Enable and Prioritize Mi Devices TV Mi Box.

How to connect your TV to Xiaomi router:

1. Connect the TV and router to the same network.
2. In the Mi Wi-Fi (or Xiaomi Home) app, go to Devices → Home Network.
3. Find your TV and assign static IP to it in DHCP settings.

If the video slows down when streaming:

• Turn off IPv6 in the router settings (sometimes causes lags).
• Reduce the bitrate in the app (for example, on YouTube, choose 720p instead of 1080p).
• Connect the TV to the router via an Ethernet cable (if the model supports RJ-45).

6. Solving typical connection problems

Even after you set it right, you can have errors, and here's a table of solutions for the most common cases:

If nothing helps:

• Reset the TV settings to factory settings (Settings → System → Reset).
• Check if the connection is blocked by antivirus on the smartphone/PC.
• Connect the TV to another source (such as a laptop) for diagnosis.

7. Optimization for gaming and smart home

Xiaomi’s 24-inch TVs are often used for retro games or as smart home panels.

• 🏠 Smart Home Integration: Connect the TV to Mi Home via Wi-Fi. Set up automation: for example, turn on the TV when you start the Xiaomi Home Security camera. Use the XiaoAI voice assistant for control (available on models with a microphone).

To reduce delays in games:

• Turn off all post-processing images on TV (Settings → Display → Additional → Noise Reduction: Off).
• Use an HDMI 2.0 cable no longer than 3 meters long.
• On the router, activate the Game Mode (if any).
