Xiaomi’s Limitless Screen: Where to Find the Feature on Mi TV, Redmi TV and Monitors

The Limitless Screen (or Bezel-less Display) mode on Xiaomi devices is a technology that visually removes the display frames, extending the picture beyond the physical screen. The feature is especially popular among Mi TV 4S/5X/6X, Redmi Smart TV and Mi Desktop Monitor monitors, but it is not always obvious where to look. In some models, the option is hidden in the depths of the menu, and in others, it requires activation through an engineering menu or firmware update.

If you can't find this mode in standard settings, the problem may lie in the software version, regional firmware, or even the hardware limitations of a particular model. In this article, we'll look at all the formal and informal ways to turn on a limitless screen, and explain why the feature may not be on your device. From simple beginner instructions to hidden commands for power users, here you'll find a solution for any situation.

What is a Limitless Screen and Why You Need It

Boundless screen technology (sometimes called Ambient Light Expansion or Edge Extension) is a software trick that creates the illusion of no bezels by:

• 🎨 Extensions of the image beyond the physical display (the effect of "filling" on the wall).
• 🔄 Adaptive illumination of the edges of the screen, simulating the continuation of the image.
• 🖥️ Hiding the interface (control panel, logos) when viewing content.

In practice, this means that movies, games and even the desktop will look more immersive, especially on the larger screens of Xiaomi Mi TV 65" or Redmi Max 98. "However, the effect does not work with all types of content: for example, in the Android TV menu or when watching 4:3 video frames will remain visible.

It is important to understand that this is not a hardware feature (unlike Samsung Odyssey curved screens), but a software image processing. Therefore, the quality of the effect depends on the power of the TV processor and the firmware version. On weak models (for example, Mi TV 4A), there may be delay or artifacts.

The official way: where to look for a setting in the Xiaomi menu

In most modern Xiaomi TVs (starting with the Mi TV 5 and Redmi TV X-series), the limitless screen feature is available through the standard menu.

1. Turn on the TV and go to the main screen of Android TV.
2. Open the settings (cog in the upper right corner).
3. Select the Display and Sound section → Picture.
4. Scroll down to the limitless screen (or Edge Extension in English firmware).
5. Activate the slider and select mode: Auto adapts to the content. Always forced on. Video only works in the player.

If the unlimited screen is not on the menu, check:

• 📺 TV model: the feature is only available on Mi TV 5/6X, Redmi TV X65/X75 newer.
• 🔄 Firmware Version: Update the Software through Settings → On TV. → Updating the system.
• 🌍 Regional firmware: on Chinese versions (CN ROM) The option may be called otherwise (for example, ).

Check the TV model in documents or on the box | Update the firmware to the latest version | Switch to Mode "Cinema" in the picture settings | Turn off the energy-saving mode-->

Hidden methods: engineering menu and ADB-team

If you don’t have an option in standard settings, but your model theoretically supports it (for example, Mi TV 4S 55 with Amlogic T972), you can try activating the function via an engineering menu or ADB.

Method 1: Engineering menu (only for power users!)

1. On the remote, press sequentially: Menu → Settings (⚙️) → All settings → The device → On TV.
2. Find the build number and quickly click on it 7 times until the notification appears You became a developer!
3. Go back to the main settings menu and open a new section for developers.
4. Activate Debugging via USB and connect the TV to the PC.
5. Enter through ADB Adb shell settings put global bezelless_display_enabled 1

Method 2: Manual editing of a configuration file (risky!)

This method requires root access and can cause system failure, and only use it if you are confident in your actions:

1. Connect to your TV on ADB and do: adb pull /system/build.prop
2. Open the build.prop file in the text editor and add a line: ro.config.bezelless_support=true
3. Save the file and download it back: adb push build.prop /system/
4. Reboot the TV.

Warning: After the hardware reset (Settings → Reset), all changes to the engineering menu and ADB will reset!

Compatibility table: on which models Xiaomi runs a limitless screen

Not all Xiaomi TVs and monitors support this feature, and here is the up-to-date compatibility table (2026 data):

If your model is not in the table, check the specifications on the official Xiaomi website or in the documentation. Sometimes the feature appears after major firmware updates (for example, switching from MIUI TV 1.x to 2.x).

Frequent Problems and How to Solve Them

Even if you've managed to activate the limitless screen, you can have problems, and here are the most common ways to fix them:

⚠️ Warning: If after the function is turned on, the screen begins to "shimmer" or color stripes appear, immediately turn off the mode and check the cables. HDMI. This may indicate overloading of the graphics processor.

• 🖼️ The effect only works in some apps Solution: In picture settings, select Forced mode for all sources (if available).+ You may need to disconnect DRM-protection in application settings.
• 🔌 Black bars on the sides remain Solution: Check the aspect ratio in the source settings (for example, on the NVIDIA Shield or Xbox set 16:9 instead of Auto).
• 🐢 Slowing the interface Solution: Turn off the effect for the Android menu TV in settings (Limitless screen) → Exceptions → System interface).
• 🔄 The function disappears after the reboot Solution: This indicates a firmware failure. Try resetting to factory settings (Settings) → Reset) or update the software manually through USB.

If the problem is not solved, try rolling back the firmware to the previous version (instructions are available on the 4PDA or XDA Developers forums). In rare cases, the limitless screen conflicts with other features, such as Dolby Vision or HDR10+.

💡

Before you experiment with firmware, back up your settings through Settings → Accounts and backups. This will save your apps and screen settings.

Alternatives to the Limitless Screen on Xiaomi

If your model does not support the official mode, you can use workarounds:

• 🎬 Mode "Cinema" in players Applications like Kodi or VLC They have a Zoom or Overscan option that mimics the image extension, and minus, they work only for video without affecting the interface.
• 🖥️ Scaling settings in Windows/macOS If the TV is connected as a monitor to the PC, in the screen settings (Win) + P → Expand) can be set a negative value Scale (for example, 95%), to get the picture out of the way.
• 🔧 Third-party launchers for Android TV Install an alternative shell (for example, ATV Launcher or Leanback Launcher – some of them support the concealment of system panels.
• 💡 Illumination of walls LED-Physical alternative: cover the TV frame with black film and install RGB-Perimeter tape synchronized with the screen via Mi Home or Philips Hue.

These methods won’t have the same effect as a real limitless screen, but they will make the viewing experience more visually immersive, and the key is not to overscale so as not to lose some of the important content (such as subtitles).

Update the firmware to activate the function

In 80% of cases, the lack of a limitless screen is due to outdated firmware. Xiaomi regularly adds support for new features in updates, but not all regions get them at the same time.

Method 1: Automatic update (recommended)

1. Go to Settings → About TV → System Update.
2. Click Check for updates.
3. If a new version is available, confirm installation. The TV will restart automatically.

Method 2: Manual update via USB (if automatic does not work)

1. Download the latest firmware for your model from the official website (choose Global Stable, not Developer).
2. Unpack. ZIP-archive and copy the file update.zip flash drive (format) FAT32).
3. Insert the flash drive into the TV, then go to Settings → About TV → Update via USB.
4. Select a file and wait for the process to be completed (don’t remove the flash drive!).

⚠️ Warning: Never use firmware from third-party sources (such as torrents or informal forums) This may result in a TV lock or loss of warranty.

After updating, check for a feature in the menu. If it is still not available, it is possible that your model does not hardware support a limitless screen (for example, due to a weak processor or lack of a light sensor).

💡

Before updating the firmware, turn off all peripherals (sound panels, game consoles) and make sure that the TV is connected to an uninterruptible power source.
