How to Check the Screen Resolution on Xiaomi Devices: From Smartphones to TVs

Screen resolution is a key parameter that affects image quality, performance and app compatibility. On Xiaomi devices (be it a Redmi Note 12 smartphone, Pad 6 tablet or Mi TV Q2), this indicator can be hidden in different sections of the menu or require special tools for accurate determination. Unlike the iPhone, where the resolution is standardized, the Xiaomi lineup offers dozens of models with screens from 720×1600 to 3840×2160 (4K), and sometimes non-standard aspect ratios.

Complicating the problem is that the manufacturer does not always specify the actual resolution in the characteristics — for example, marketing terms like “FHD+” or “2.5K” can mask the actual pixels. This article will help to accurately determine the resolution of your Xiaomi device, taking into account the features of MIUI, Android TV and hardware limitations. We will look at both standard methods (through system settings) and advanced ones using ADB, engineering menus and third-party utilities.

1. Verification through system settings (for smartphones and tablets)

The easiest way is to use the built-in MIUI tools. It is suitable for most Xiaomi, Redmi and POCO smartphones based on Android 10-14. However, note that in some firmware (especially global versions), the resolution partition may be hidden or display incomplete data.

Instructions:

• 📱 Open the Settings app (cog icon).
• 🔍 Go to the About Phone (or About the Tablet) section).
• 📝 Find All Specifications or Specifications (in some versions) MIUI — Additionally).
• 🖥️ Scroll to the Display block – permission should be indicated here (for example, 1080 × 2400).

💡

If the specifications are only FHD+ and there is no exact resolution, try alternative methods in the following sections. Often the manufacturer rounds up the values for marketing (for example, 2340×1080 instead of the standard 1920×1080).

On Xiaomi Mi TVs, the way is different:

1. On the remote, press Settings.
2. Select Display & Sound → Picture → Advanced settings.
3. The Resolution item will show the current (not maximum!) signal resolution. For complete data, use the methods in Section 4.

2.Use of the engineering menu (#4636##)

Android’s hidden engineering menu provides advanced display data, including real-world resolution, pixel density (DPI), and refresh rate, a technique that works on most Xiaomi devices but can be blocked in some regional firmware (such as India or China).

How to open it:

1. Open the Phone app.
2. Enter the combination: ##4636## (no spaces).
3. In the menu that appears, select Phone Information (or Usage Statistics in newer versions).
4. Scroll to the Display block, and you'll find the following options: Resolution, the actual resolution (e.g., 1080×2400), Density, the pixel density (DPI, which affects zoom), Refresh rate, the screen refresh rate (e.g., 120Hz).

⚠️ Warning: Do not change the parameters in the engineering menu if you do not understand their meanings! DPI It may cause the interface to fail. MIUI, a change in refresh rate – to overheat the screen.

3. Third-party applications for accurate diagnostics

If standard methods don't give you the full information, we'll have specialized tools to help you, and they'll not only show resolution, but they'll also provide data on color gamut, matrix type (AMOLED/IPS), and even the screen manufacturer. We tested 5 popular applications -- the results in the table below.

Recommendation: For maximum accuracy, use DevCheck or AIDA64. These applications read data directly from the display drivers, so they show real resolution even on devices with custom firmware. For example, on Xiaomi 13 Ultra with a resolution of 3200×1440, they will display the exact value, while in the system settings, they can indicate a rounded “2K”.

4.Permission check on Xiaomi TVs (Mi TV, Redmi TV)

Xiaomi TVs on Android TV or PatchWall often hide the real resolution of the matrix in favor of marketing terms ("4K HDR", "QLED"). To find out the exact parameters, you will have to use a combination of methods.

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

• 🔌 Turn off the TV from the socket.
• 🖱️ Press the Menu buttons. + Volume Down on the remote.
• 🔌 Turn the TV on the network, holding the buttons for 10-15 seconds.
• 📺 In the service menu, find the Panel Info section - here will be the matrix model and native resolution.

⚠️ Attention: Incorrect actions in the service menu can lead to resetting the TV settings or even blocking the download.If you are not sure, use Method 2.

Method 2: A Safe Method (ADB)

Connect the TV to your PC via Wi-Fi or Ethernet and follow the command:

adb shell dumpsys display

In the output, find the mOverrideDisplayInfo string, where the current resolution will be indicated (for example, 3840x2160 for 4K).

adb shell getprop ro.sf.lcd_density

💡

On Xiaomi TVs with Amlogic processors (such as Mi TV 4S), the actual resolution may differ from the stated one due to upscale, for example, a matrix with a resolution of 1920×1080 can impersonate “4K” due to software processing.

5. Advanced Method: ADB and Hidden Commands

If previous methods didn’t work (for example, on devices with custom firmware or blocked engineering menus), Android Debug Bridge (ADB) remains. This method is universal and works on all Xiaomi devices, including older models on MIUI 8-9.

Step-by-step:

1. 🖥️ Install. ADB Tools on PC.
2. 📱 Turn on Debugging. USB on your smartphone: Go to Settings → About the phone. Press 7 times on the version. MIUI, To activate the developer mode. Go back to Settings. → Additionally. → For developers and enable debugging by USB.

adb shell wm size

The answer is in Physical size: 1080x2400.

adb shell wm density

Important: On some Xiaomi devices with dynamic resolution (e.g. Redmi K60 Pro), the wm size command can show the current value rather than the maximum.

adb shell dumpsys display | grep mBaseDisplayInfo

Determination of the device model resolution

If your Xiaomi device is not turning on or the screen is damaged, but you know the exact model, you can get the resolution by technical specifications. We collected data for popular lines (2020-2026):

To clarify the data on a particular model:

1. Find a sticker on the box or under the battery (for smartphones) with the full name (e.g. Xiaomi 23013PC75G for Redmi Note 12 Pro 5G).
2. Check the model in the GSMArena database or on the official Xiaomi website.
3. Note that there may be several screen modifications for one device (for example, the POCO X5 Pro was produced with matrixes from different manufacturers).

7. Frequent mistakes and how to avoid them

When checking permission, users often encounter inaccurate data or technical difficulties, and consider typical problems and solutions:

• 🔄 Shows current resolution rather than maximum: This is true for dynamic scaling devices (e.g. Xiaomi) 13T It can automatically lower the resolution to save charge. To see the real value, turn off the power saving mode or use the power saving mode. ADB.
• 📵 Engineering menu not open: On some firmware (for example, MIUI EU) The alternative is applications like this. MTK Engineering Mode (for devices running MediaTek processors).
• 🖥️ The TV displays signal resolution, not screen resolution: That's OK - so is Android TV It shows the current input stream. Use the matrix data to get the input stream. ADB service-menu.
• ⚠️ After checking through ADB screen started flickering: 'Probably changed refresh rate.' Return standard settings with command: adb shell wm size reset

💡

If none of the methods worked, check the device for custom firmware (such as LineageOS), in which case the resolution can be modified software, and to determine it will require analysis of the build.prop file.
