In this article, we will discuss all working ways to activate an infinite screen – from standard settings. MIUI You'll learn how to properly calibrate the screen boundaries, avoid artifacts when watching videos, and return the original settings if something goes wrong. And also a unique method for Xiaomi TVs with an Amlogic processor, which is not documented in official instructions.

What is an Infinite Screen and Why You Need It

Infinite screen (Full Screen Display or Edge-to-Edge) is a display mode in which content is stretched across the entire physical display, hiding:

• 📱 System panel notifications (on smartphones)
• 🎮 Lower navigation bar (Back, Home, Recent buttons")
• 📺 Black frames on the edges of the screen (on TVs)
• 🖥️ Status indicators (time, battery charge, network signal)

Main advantages:

• 🎬 Immersive Video Viewing – Movies and games occupy 100% of the screen without black bars.
• 📲 More space for content – in the browser or messengers displayed on 10-15% more information.
• 🎨 Aesthetics – the device looks more modern, especially on models with curved edges (Mi 11 Ultra, Redmi) K50 Pro).

But there are pitfalls:

⚠️ Note: Some Xiaomi TVs (e.g. Mi) TV Q1E) Forced stretching of the image can lead to cropping of subtitles or distortion of proportions in games. Before activation, check whether your model supports Overscan (screen overflow).

Preparation of the device before setting up

Before turning on the infinite screen, follow the mandatory preparatory steps:

1. Update your firmware. On your TVs, go to Settings. → On TV. → Software Update. On smartphones: Settings → The phone. → System Update: Minimum versions for stable operation: 📺 Televisions: MIUI TV 3.0+ (or PatchWall 4.0.+) 📱 Smartphones: MIUI 13+ (for models of 2022 and newer)

Make a backup copy.

Settings → Accounts and security → Backup

Mi Cloud

Settings → Additional → Backup and Reset

Turn off the power saving.

Settings → Battery and productivity → Energy saving regime → Turn it off.

For Xiaomi TVs with Amlogic processor (Mi models) TV 4S/4A) additionally:

Shut down. HDMI-CEC In Settings → Connections → HDMI-CEC|

Set screen resolution on 1920×1080@60Hz (even if TV supportive 4K)|

Reset the image settings in Settings → Display and sound → Resetting image settings|

Connect the TV to the network via Ethernet cable (Wi-Fi can cause lags when calibrated)-->

If you are setting up a smartphone, make sure that:

• 🔄 All navigation gestures are disabled (go to Settings) → Display. → Full screen mode → Type of navigation → Buttons).
• 🔒 No active VPN Firewalls that can block system services.
• 🛠️ Developer mode is enabled (7 times click on Version) MIUI In Settings → The phone).

💡

On Xiaomi TVs, before calibrating the screen, turn on the Game mode (Settings) → Display and sound → Image mode → This will turn off post-processing, which will make it easier to set the boundaries.

Method 1: Standard settings via MIUI (for smartphones)

Most of Xiaomi’s smartphones (starting with the MIUI 12) support an infinite screen through the built-in settings:

1. Open the Settings → Display.
2. Select Full Screen Mode (or Full Screen Display on English firmware).
3. Activate the option to Hide the cutout (for models with a "brow" or a hole under the camera).
4. Enable Automatic Hiding of Panels for Immersive Mode.

For fine tuning:

• 🔧 Manual Calibration: In the same menu, select Full-screen Mode Setting and adjust the indentations from top/bottom with sliders.
• 🎯 Exceptions for applications: In Full-screen mode → Exceptions include applications where an infinite screen is not needed (e.g. banking software).

If the option is not Full-screen mode:

1. Activate the Developer Mode (as described above).
2. Go to Settings → Additional → For developers.
3. Find Minimize the notches in the apps and turn it on.
4. In the same menu, activate Forced Full Screen Display (may cause bugs in some apps!).

Method 2: Hidden settings for Xiaomi TVs

On Xiaomi TVs, the infinite screen is configured differently through the Overscan menu, which is hidden in the standard interface, but it can be activated in two ways:

Method A: Through the Engineering Menu (for Amlogic models)

1. Turn on the TV and go to any HDMI-entrance.
2. On the Xiaomi remote, click sequentially: Menu → Settings → All Settings → General → Device Preferences → Picture → Advanced Settings
3. Enter the code: 4725 (the hidden menu will open).
4. Choose. HDMI Overscan and set the value 0% (switch off the trimming) or 2-5% (If the image is out of the way).

Method B: Through ADB-Teams (for all models)

If the engineering menu is not available, use it. ADB (Android Debug Bridge):

1. Install Platform Tools on your PC.
2. Connect the TV to the same Wi-Fi network as the computer.
3. Enable Wi-Fi debugging in your TV settings (Settings) → On TV. → Version. → 7 times to press the "Android Version").
4. Run the command line on the PC and execute: adb connect IP_yours_TV:5555 adb shell settings put global overscan.custom 0 adb shell settings put global overscan.enable 1
5. Reboot the TV (adb reboot)

To calibrate the boundaries manually use the commands:

adb shell settings put global overscan.left 5 # indentation left (pixels)


adb shell settings put global overscan.right 5 # indentation right




adb shell settings put global overscan.top 10 # indentation from top




adb shell settings put global overscan.bottom 10 # indentation from the bottom

⚠️ Attention: On the TVs Xiaomi Mi TV Q2/Q1E MediaTek-based ADB For overscans, you may not work. In this case, use an alternative method through configuration files (described in the next section).

💡

On Xiaomi TVs with PatchWall after setting up Overscan, be sure to reset the app cache (Settings) → Annexes → Cache resets; otherwise, some services (e.g. Netflix) may be displayed with black bars.

Method 3: Manual editing of configuration files (advanced)

If standard methods don't work, you can change the system configuration files, which is suitable for power users and requires root rights or access to the system. ADB (TV-wise).

For smartphones (requires Magisk or TWRP)

1. Install a file manager with root support (such as Solid Explorer).
2. Go to /system/build.prop
3. Add the lines: qemu.hw.mainkeys=0 ro.miui.has_real_bl=1 ro.miui.notch=0
4. Save the file and restart the device.

For TVs (without root, through) ADB)

1. Connect to the TV on the TV. ADB (as in the previous section).
2. Download the current configuration file: adb pull /system/vendor/etc/display_settings.xml
3. Open the file in the text editor and find the block: <overscan> <left>0</left> <right>0</right> <top>0</top> <bottom>0</bottom> </overscan>
4. Change the values to the desired ones (for example, <left>-5</left> left-panel).
5. Save the file and download it back: adb push display_settings.xml /system/vendor/etc/ adb reboot

For Mi models TV P1/P1E Google TV The path to the file may be different:

/system/etc/display_settings.xml

⚠️ Note: Incorrect editing of build.prop files or display_settings.xml Before making changes, back up the original files with the command: adb pull /system/build.prop build.prop.bak

Solving problems after setting up

If you have problems after activating the infinite screen, use this instruction:

For Xiaomi TVs with display problems through HDMI:

• 🔌 Reset the settings. HDMI-Port: Go to Settings → Connections → HDMI → Resetting settings HDMI.
• 📊 Change the color mode: On the menu HDMI choose RGB Instead of YCbCr (can eliminate artifacts).
