Modern Xiaomi smartphones are famous for their displays, but standard factory settings often hide some of the functionality, leaving “dead zones” or black fields at the edges. Users seeking maximum immersion often wonder how to make a limitless screen on Xiaomi so that the content takes up all available space without indentations. This is especially true for models with notch or rounded edges, where the system frames can visually reduce usable area.
The limitless display effect can be achieved in a number of ways, from simple manipulations in the standard settings menu to the use of engineering mode and third-party utilities. Changing the density of DPI, managing hidden fields and adjusting the operation of specific applications allows you to significantly expand the boundaries of the information displayed. It is important to understand that each Mi, Redmi or Poco model can have its own features of implementing the MIUI or HyperOS interface.
In this article, we will take a closer look at secure customization methods that don’t require root rights, but produce visible results, learn how to remove system indentations, configure full-screen mode for older applications, and use hidden Android features to expand the visual space.
Full-screen management in MIUI
The first and safest step to creating a limitless image is to configure the system settings for displaying applications. The MIUI Operating Shell has a built-in mechanism that forcibly stretches content to the entire screen, ignoring standard proportions. To access these settings, you need to go to the Settings menu → Screen → Full-screen mode.
Here you'll see a list of all the applications installed. The system automatically determines which ones support modern aspect ratios and which require manual adjustments. Activating the switch in front of the desired application causes the system to ignore the black fields at the top and bottom, stretching the picture over the entire available matrix.
- 📱 Open the system settings and find the Screen section».
- 🔍 Select “Full screen mode” to manage applications.
- ✅ Activate switches for all programs where you want to remove the frames.
- 🔄 Restart modified applications to apply parameters.
It is worth noting that in some cases stretching can lead to distortion of the interface or cropping of important controls. The most critical system applications are better left in standard mode to avoid navigation failures. If you notice that after you turn on full-screen mode buttons are no longer available, return the setting to the original state.
Adjust the DPI density through
A more advanced method to visually enlarge the workspace and create a “limitless” effect is to change the pixel density (DPI), which measures how many interface elements fit per inch of the screen. Increasing the DPI value makes all elements smaller, allowing more information to fit and visually minimize the frames.
To access this feature, you need to activate the developer mode. Find the About Phone menu and quickly click 7 times on the MIUI build number. Once the "You've become a developer" notification appears, go to Settings → Advanced Settings → For developers. Find the "Minimum Width" option (or Smallest Width).
Write down the initial value before making changes so you can roll back the settings if necessary. Standard values for Xiaomi smartphones are usually in the range of 360 to 420 dp. Increasing this number by 20-40 units gives a noticeable effect of expanding the space, but does not break the layout of the interface.
💡
Do not set the DPI above 600 unless absolutely necessary, as this can make the text unreadable and cause system instability.
Changing pixel density affects the entire interface globally, which means icons, fonts and widgets will become smaller, making it feel like the screen has gotten bigger, but over-magnifying can make some controls too small to be easily pressed.
Use of the Engineering Menu for Calibration
The Engineering Mode is a hidden part of the system designed to test hardware and deep-tuning the display, which is accessed through a set of special code in the Phone app. For most Xiaomi devices, the code ##6484## or #4636## is current.
Inside the menu, look for sections related to Single Test or Version Information, where sensor and display calibration options are sometimes available. In some firmware versions, you can find settings that allow you to adjust the touchscreen response area, which indirectly affects the perception of the screen's limitlessness.
| Parameter | Description | Recommended action |
|---|---|---|
| Touch Panel Test | Sensor response verification | Make sure there are no dead zones |
| LCD Test | Color and Broken Pixel Test | Check the uniformity of the glow |
| Version Info | Driver information | Confirm with current firmware |
| TP Version | Touchscreen version | Information only |
⚠️ Warning: Be extremely careful in the engineering menu. Changing unknown parameters can cause the touchscreen or display to malfunction.
Users often confuse the engineering menu with the ADB-If the standard codes don't work on your Redmi Note or Xiaomi Mi model, it may be that the menu is closed by the operator or manufacturer, and it's safer to limit it to the standard display settings.
What to do if the engineering menu code doesn’t work?
Hiding the cutout (Notch) for full immersion
One of the main obstacles to the "limitless" screen is the cutout for the front camera. Visually hiding this element creates the illusion of continuity of the image. MIUI settings include the "Hide the cutout" function, which paints the area around the camera in a black stripe, turning a rectangular cutout into a flat status bar.
To activate this feature, go to Settings → Screen → Hiding the Cut (the path may vary depending on the OS version). Here you can choose the mode for each application separately or set a global rule, this is especially useful in games and video players, where the black bar on the top looks more aesthetically pleasing than the interrupting hole.
- 🎮 Open the screen settings in the smartphone menu.
- 👁️ Find the item “Hiding the cutout” or “Camera in the cutout».
- 📺 Select the app from the list or use the global setting.
- ⚫ Select the “Hide the Notch” mode to create a black stripe.
Using a dark theme in combination with hiding the cutout gives the best result: When the top panel of the interface turns black, it merges with the screen frame, making the boundaries of the device less noticeable, a simple but effective trick for visually expanding the space.
☑️ Screen preparation checklist
Third-party applications for interface management
If built-in tools are not enough, third-party apps from Google Play come to the rescue, programs like SecondScreen or various launchers allow you to fine-tune the resolution and density of the interface, but the most effective are applications that work through ADB (Android Debug Bridge), since they do not require root rights to make system changes.
One popular solution is to use utilities to change the resolution of the screen, which can force the native resolution of the matrix, which is sometimes reset to lower values by the system to save energy, and there are applications that hide the system navigation bar, replacing it with gestures.
These utilities often require a computer connection or USB debugging. ADB commands allow you to change the display settings on the fly. For example, the command to change the density is as follows:
adb shell wm density 450A team to reset to factory value:
adb shell wm density reset⚠️ Note: Using third-party apps to change system settings can lead to unstable work.Make sure you know how to reset your settings via your computer if your smartphone screen becomes unreadable.
Optimization of Games and Multimedia
Content optimization deserves special attention. Even if you set up a system, you may find that a particular game or video does not occupy the entire screen. Xiaomi has Game Turbo mode, which has its own display settings. Go to the Security application → Game Turbo → Settings and check the zoom parameters.
For video content, most modern players (for example, MX Player or VLC) Select "Size by screen" or "Fill" to remove the black fields on the sides if aspect ratio_ Videos do not match the display proportions of your Xiaomi.
It’s also worth checking the settings of a particular app. In some social media or streaming services, the Full Screen option is inside their own settings menu, not in the system. Regularly updating apps ensures they work correctly with new screen standards.
💡
Integrated approach: the combination of DPI system settings, cutout hiding and proper application configuration gives the best effect of a limitless screen.
