Xiaomi tablet as a monitor: 5 ways to connect + setup without lags

Turning a Xiaomi tablet into an additional monitor is a practical solution for expanding the workspace, streaming or games. Modern models of Redmi Pad, POCO Pad and Xiaomi Pad 6 support the output of images from a PC / laptop via USB-C, Wi-Fi or wireless protocols like Miracast. But not all methods are equally effective: somewhere there will be delays, somewhere you will need adapters, and some functions work only on Windows 11 or macOS Ventura.

In this article, we will analyze all current methods of connection, taking into account the features of the firmware MIUI You'll learn how to avoid a connection break during transmission. 4K, Why on the Xiaomi Pad 5 It may not work through the sound HDMI-alternative, and what settings will reduce the delay to acceptable 30-50 And also — the table of compatibility of models with different types of connections and checklist for diagnosing problems.

Spoiler: If you want a monitor for games or video editing, wireless solutions like SpaceDesk or Duet Display won't work because of the high input lag. Here, you'd better consider USB-C with DisplayPort Alt Mode -- but only if your tablet and PC support this standard. You can check this in the device's specifications or through the dxdiag command in Windows (the Screen tab).

1. Compatibility Check: Which Xiaomi Tablet Can Be Used as a Monitor

Not all Xiaomi tablets are equally good at second screen.

• 🔌 Presence USB-C DisplayPort Alt Mode, which allows you to transmit video directly without converters. 6/Pro, Redmi Pad Pro, but not in the Redmi Pad SE.
• 📶 Wi-Fi version: Wi-Fi 6 is needed for wireless transmission without lags (802.11ax) Wi-Fi 5 with 5GHz support, and Wi-Fi 4 tablets (such as the old Mi Pad 4) will slow down.
• 🖥️ Screen resolution: if the tablet has a matrix 2K+ (Like Pad. 6 Pro 2880×1800), The PC only gives you Full. HD, The image will be stretched or cut.

Xiaomi has not officially announced a “monitor mode” feature for its tablets (unlike the Samsung DeX or Huawei Multi-Screen), but there are workarounds – and they work more stable than universal applications like TeamViewer or AnyDesk, which give a delay of 100+ ms.

💡

Before buying adapters, check the supported protocols of your tablet in the documentation. For example, Xiaomi Pad 5 does not support HDMI-in, but works with USB-C → HDMI via DisplayPort Alt Mode (you need an active cable).

2. Method 1: Connect via USB-C (DisplayPort Alt Mode) - minimal delays

This is the most reliable method for tablets with DisplayPort support via USB-C. Suitable for games, video editing or graphics where latency is critical.

• 🔗 Active cable USB-C → HDMI/DisplayPort (Passive doesn't work! -- CableMatters, for example. 201056 or UGREEN 40467.
• 💻 PC/laptop with port USB-C/Thunderbolt (adapter USB-A → USB-C video-enabled).
• ⚡ Power supply for the tablet (with prolonged operation, the battery discharge will accelerate).

Step-by-step:

1. Connect the cable to your tablet and PC. The tablet screen should display a notification "USB: Image Transfer".
2. On Windows, press Win + P and select “Extend” or “Duplicate”.
3. If the image does not appear, check in the Control Panel → Devices → Displays, whether a second monitor is detected.
4. MIUI may need to allow debugging over USB: go to Settings → About Phone → MIUI Version (click 7 times), then to Settings → Additional → For Developers → Debugging over USB.

⚠️ Note: On Xiaomi Pad 6 when connected via USB-C Solution: In Windows audio settings, manually select the output device "Digital audio (DisplayPort)".

Method 2: Wireless Miracast connection (without cables but with lags)

Miracast is a wireless image transfer standard supported by all Xiaomi tablets on MIUI 12+. Pros: no wires, cons: delay 50-150 ms (unsuitable for gaming) and possible artifacts with a weak Wi-Fi signal.

How to connect:

1. On the tablet: Settings → Connection and Sharing → Screen Transfer (or “Wireless Display”).
2. On PC (Windows 10/11): Win + K → select your tablet from the list.
3. On macOS: Use AirPlay (but Xiaomi doesn’t support it directly – you need 5KPlayer or ApowerMirror).

If the connection breaks:

• 📡 Switch the router to a 5 GHz channel (in the router settings).
• 🔄 Reduce transmission resolution in Miracast settings (e.g., with 1080p on 720p).
• 🔋 Turn off Wi-Fi energy saving on your tablet: Settings → Battery → Performance mode.

⚠️ Attention: MIUI 14 In some regions, the "Wireless Display" function is hidden. To enable it, do: adb shell settings put global. hidden_wireless_display 0 After that, the item will appear in the connection menu.

Method 3: Applications for screen duplication (SpaceDesk, Duet Display, Spacedesk)

If native methods don't work, third-party utilities come to the rescue, and they fall into two types:

• 🖥️ Screen streaming (SpaceDesk, Spacedesk) – transmit the “picture” over the network with a delay 50-200 miss.
• ⚡ Direct connection (Duet Display, iDisplay) USB/Wi-Fi Expanding the desktop (laden less, but paid).

Comparison of popular applications:

Instructions for SpaceDesk (free option):

1. Download server software to your PC and client application to your tablet.
2. Connect both devices to the same 5GHz network.
3. Run the server on your PC, and on the tablet, select it from the list of available displays.
4. In SpaceDesk settings, reduce the bitrate to 10-15 Mbps if there are lags.

💡

For minimal delays in Duet Display, use USB-C+ connection to turn off anti-aliasing in the app settings.

5. Method 4: Connecting through HDMI-Adapter (for tablets without DisplayPort)

If your tablet doesn’t support DisplayPort Alt Mode, but it does have USB-C, you can try a USB-C → HDMI adapter with a chip converter (for example, based on Realtek RTL9210).

• 🔄 Most adapters only work in the mode. MHL (Mobile High-Definition Link, which requires support from the tablet. on Xiaomi, this only works on older models (Mi Pad 4).
• 💡 Modern tablets (Pad 6, Redmi Pad Pro) do not support MHL, But they can work with adapters that emulate. USB-display (e.g., Plugable) UD-3900).
• ⚠️ The delay in this connection is 100-200 MS – suitable only for office tasks.

How to connect:

1. Buy an adapter with USB 3.0 → HDMI support (e.g. WAVLINK USB3-HDMI2).
2. Connect the adapter to the tablet, and then HDMI-plug-in.
3. On a PC, install the driver from the adapter manufacturer’s website (DisplayLink is often required).
4. In Windows Screen Settings, select Expand mode.

⚠️ DisplayLink-based adapters do not work with protected content (Netflix, Disney)+, play DRM). For such cases, use it. USB-C → HDMI DisplayPort Alt Mode.

6.Tune Xiaomi tablet as a monitor: image optimization and performance

Even after a successful connection, you may have problems with resolution, color reproduction, or performance.

• 🎨 Color Profile: In Windows, go to Screen Settings → Additional parameters → Colors and select "sRGB" for natural transmission.
• ⚡ Performance: On the tablet, turn off animation: Settings → The phone. → Version. MIUI (7 taps) → Developer settings → Scale of animation (off.).
• 🔋 Power: Connect the tablet to charging - at a discharge below 20% MIUI Automatically reduces productivity.

Solving common problems:

💡

If the Xiaomi Pad 6 tablet is not defined as a monitor in Windows 11, upgrade the graphics card driver to version 531.41+ (for NVIDIA) or 31.0.101.4355+ (for Intel).

7.Alternative options: when Xiaomi tablet doesn't fit as monitor

If none of these methods worked, consider alternatives:

• 🖥️ The Xiaomi Mi Desktop Monitor is a low-cost monitor. 1C (23.8", Full HD) It is cheaper than a tablet + adapter.
• 📱 Smartphone as a monitor: Redmi Note 12 Pro+ s AMOLED-120Hz screen could be a temporary replacement.
• 🌐 Cloud PC: Services like Shadow PC GeForce NOW allow you to stream the desktop to the tablet with minimal lags.

A critical nuance: Xiaomi tablets on MediaTek processors (such as the Redmi Pad with the Helio G99) often have problems with DisplayPort drivers, in which cases wireless solutions like SpaceDesk will be more stable than USB-C.
