How to set up Chromecast on a Xiaomi TV: a complete guide from connectivity to fine-tuning

Why Chromecast on Xiaomi TV requires a special approach

Xiaomi TVs with Android TV or Google TV should theoretically support Chromecast out of the box — these are related technologies from one developer. However, in practice, users face nuances ranging from the lack of a stream icon in apps to problems with screen resolution when streaming. Xiaomi often modifies the firmware to its needs, removing or limiting some of Google’s features.

This article doesn’t just repeat the standard Chromecast connection instructions, it reveals the hidden MIUI TV settings that affect broadcast stability, and explains how to get around typical limitations, such as why some Xiaomi Mi TV 4S or Redmi Smart TV Chromecast models only work after power saving mode is turned off, or how to get content to be streamed in 4K HDR if the TV persistently lowers the resolution to 1080p.

Preparing Xiaomi TV to work with Chromecast

Before you connect to Chromecast, you need to make sure that the Xiaomi TV is ready to receive streaming content.

• 📺 Android version TV/Google TV: lower 9.0 (support for Chromecast Ultra or 4K-streaming required 10.0+). You can check the version in Settings → On TV. → POS version.
• 🔄 System updates: Xiaomi often releases patches to fix Chromecast issues.Update firmware through Settings → On TV. → Updating the system.
• 🌐 Network Connection: Chromecast requires stable Wi-Fi at 5GHz (for the first time) 4K) or 2.4 GHz (for Full) HD). Avoid mixed networks (such as Wi-Fi 6) + Wi-Fi 5), which can cause connection breaks.
• ⚡ Power Saving Mode: Turn it off in Settings → Power supply → Power saving mode, otherwise the TV may fall asleep during the broadcast.

Pay special attention to the HDMI-CEC settings (in Xiaomi called MI AnySee or HDMI Management).This feature allows you to control the Chromecast from the TV remote, but sometimes conflicts with the Google Cast protocol. If the device does not respond to commands after connecting, try disabling MI AnySee in Settings → Devices and Accessories → HDMI-CEC.

Step-by-step: how to connect Chromecast to Xiaomi TV

The connection process depends on the type of your Chromecast:

• 📱 Chromecast (if the TV supports Google Cast directly).
• 🔌 External Chromecast (device connects to port) HDMI).

Let's look at both options.

Option 1: Use the built-in Chromecast (Google Cast)

1. Make sure that the TV and smartphone/tablet are connected to the same Wi-Fi network.
2. Open the app that supports the broadcast (for example, YouTube, Netflix, Google Photos).
3. Click on the broadcast icon (usually looks like a rectangle with a Wi-Fi signal in the lower left corner).
4. In the list of devices, select your Xiaomi TV (the name will match the model, for example, Mi TV 4S-55).

If the broadcast icon does not appear:

Reset network settings on TV |Reboot router | Update app on smartphone | Check on Wi-Fi on TV

-->

Option 2: Connecting an external Chromecast

1. Connect your Chromecast device to the free HDMI port on your TV.
2. Use the original power supply (some HDMI ports on Xiaomi TV don't provide enough power for Chromecast 4K).
3. Switch the TV to the appropriate signal source (Source or Input button on the remote).
4. Follow the on-screen instructions to set up Chromecast through the Google Home app on your smartphone.

If your TV doesn’t recognize Chromecast, try connecting it to your TV. HDMI-External powered hub is a common problem on Redmi Smart models TV X due to limited port capacity.

💡

If Chromecast doesn’t connect to Wi-Fi, try temporarily disabling Smart Wi-Fi in your router settings (it can block multicast packets needed to run Google Cast).

Configure the broadcast quality and solve delay problems

One of the most common complaints users have is lag when streaming or automatically lowering the resolution to 720p, which is due to settings on both the TV and the router.

For fine-tuning of quality:

1. Open the Google Home app on your smartphone.
2. Select your Chromecast → Settings (cog) → Video.
3. Set the parameters: 🎞️ Permission: 4K (3840×2160) or 1080p (if the router does not support 5 GHz). 🎨 Color palette: HDR10 Dolby Vision (if the TV supports the TV). 🔊 Sound: Auto (recommended) or PCM (If you have a problem with Dolby).

⚠️ Attention: On Xiaomi Mi models TV P1 and Q2 choice 4K HDR Chromecast can cause a flickering screen. In this case, set manually. 4K SDR Update the TV firmware to the version MIUI TV 3.0+.

Advanced Settings: How to Make Incompatible Applications Work

Some apps (such as Disney)+, Apple TV, Local streaming services may block the broadcast on Chromecast because of the DRM-Here are the detours:

• 📱 Screen Mirror: Turn on Screen Broadcast in the Android notification curtain (works unstable but is suitable for apps without built-in Cast support).
• 🖥️ Chromecast via PC: Install the Google Cast extension for Chrome browser and stream the tab with the web version of the service.
• 🔧 Change of region: In the settings of Chromecast (Google Home) → The device → Settings → Location: Establish the region where the service is officially supported (e.g., the United States for the HBO Max).

To mirror the screen with Xiaomi-/Redmi-smartphone:

1. Activate the Wireless Display in Settings → Connections and Sharing → Screen Broadcast.
2. Select your Chromecast from the list of devices.
3. Confirm the connection on the TV.

⚠️ Note: Screen mirroring consumes significantly more resources than live streaming via Cast. On weak routers (such as single-core processor), this can cause strong lags. For stable operation, a router with Wi-Fi 6 or MU-MIMO.

Solving Common Chromecast Errors on Xiaomi TV

Even after you set it up correctly, you can still get errors, and here are the most common ways to fix them:

If Chromecast is connected, but the broadcast is interrupted every 5-10 minutes:

1. Turn off Auto Update in your TV settings (Settings → About TV → System Update → Auto Update).
2. In router settings, increase DHCP Lease Time to 24 hours (often 1 hour by default).
3. For external Chromecast use USB-power hub if the device overheats.

💡

If after all the manipulations Chromecast still does not work, try to reset it to factory settings: press the button on the case of the device for 25 seconds, until the indicator begins to flash orange.

Optimizing Chromecast for gaming and low latency

Chromecasts can be used not only for video, but also for cloud gaming (for example, Google Stadia, Xbox Cloud Gaming, or NVIDIA GeForce NOW). However, standard settings give a delay of 100-150 ms, which is critical for shooters or racing.

• 🎮 Use an Ethernet adapter for Chromecast (even if the TV is connected over Wi-Fi, a wired connection for the device will reduce latency by 30–50 ms).
• 📶 Set up QoS on your router: Prioritize Chromecast traffic over your router MAC-Address (you can find it in Google Home) → The device → Settings → Technical information).
• ⚡ Turn off post-processing on the TV: go to Settings → Picture → Movement → Smoothing movement and set off..

For Stadia on Xiaomi TV:

1. Make sure that the Chromecast settings enable Stadia Optimized (available in Google Home for Chromecast Ultra and newer).
2. Use a Stadia Controller with a direct Wi-Fi connection (not via Bluetooth) to reduce input latency.
3. If the game is slowing down, lower the resolution in the Stadia settings to 1080p – this will reduce the load on the network.

On Xiaomi Mi TV Q1 and newer models, you can additionally activate the game display mode:

Settings → Display and sound → Image mode → Game

This disables post-processing and reduces latency to 50–70 ms (versus 100+ ms in standard mode).
