How to find out the screen resolution on Xiaomi phone: from Redmi Note to POCO F6

You bought a new Xiaomi or you want to sell the old one, but you don't know what the screen resolution is? This information is critical for choosing games, adjusting the interface to zoom in or comparing with other models. Unfortunately, the manufacturer does not always specify the exact display parameters on the box or in brief specifications - especially for the budget lines of Redmi and POCO.

In this article, we will discuss 5 working ways to find out the screen resolution on any Xiaomi phone – from the flagship Xiaomi 14 Ultra to older models like Redmi. 4X. You'll learn to check the settings through standard settings, engineering menus, third-party apps, even without your smartphone on, and at the end of the day, you'll have a permission table for 50.+ popular.

1. Through phone settings: the easiest way

If your Xiaomi runs MIUI 12 and later, you can get a 30-second screen resolution without installing any additional software, a method that works for 90% of current models, including the Redmi Note 12 Pro+, POCO X5 Pro and Xiaomi 13T.

Instructions:

📱 Open the Settings app (cog icon on the home screen).
🔍 Scroll down and select About Phone (or About Device on some firmware).
📊 Tap on item All characteristics (in older versions) MIUI — Characteristics of equipment).
🖥️ Find the screen resolution line – here will be the value in the format 1080 × 2400 or similar.

☑️ What to do if there is no item "All characteristics"

Settings → About the phone → System updateSettings → DisplayAIDA64Try the Engineering Menu (Section 4)

Done: 0 / 4

⚠️ Note: Some models (e.g. Redmi) 9A or POCO M3) In the specs, you can only display the screen size in inches, but not the resolution.

Also, look at the pixel density (DPI) parameter in the same menu, which shows how many pixels are per inch of the screen — the higher the value, the clearer the picture. For example, the Xiaomi 13 Pro has a density of 446 PPI, and the Redmi A2 has only 269 PPI.

2. Through display parameters (for MIUI 14+)

In recent firmware versions, Xiaomi has added a hidden ability to view the screen’s technical data directly in the display settings, which works on Xiaomi 14, Redmi Note 13 Pro+ and other devices from 2023-2026.

How to check:

Go to Settings → Display.
Slap the icon. ⋮ (three dots) in the upper right corner and select Additional.
Scroll down to the Technical Information block – here will be the Physical Resolution line.

🔹 Note: If you have AMOLED-screen (like Xiaomi) 12S Ultra, this menu will also show the matrix type and support HDR10+ Or Dolby Vision.

3. with the help of applications: AIDA64 and CPU-Z

If standard methods don't work, third-party utilities will come to the rescue, and the two most reliable performance-checking apps are AIDA64 and CPU-Z. They show not only the resolution, but also the CPU model, the RAM capacity, the Android version and other parameters.

Instructions for AIDA64:

📲 Install. AIDA64 Google Play.
🔧 Open the application and go to the Display tab.
📏 In the screen resolution block, you will see the current values (for example, 1080 × 2400 pixel).
🔄 Below is the maximum resolution of the matrix.

What else can you learn from AIDA64?

🔋 Type of battery and its current capacity.
📡 Supported networks (4G, 5G) and frequencies.
🎮 GPU model (e.g. Adreno 740 in Xiaomi 13).

💡

If AIDA64 shows a resolution of 720×1600, but you are sure that the model should have Full HD, check the zoom settings in Settings → Display → Font and Display Size.

⚠️ Note: Some of the firmware (especially custom) AIDA64 It may show incorrect resolution due to errors in the Android kernel, in which case, check the data with the official specifications of the model on the Xiaomi website.

If you’re not afraid to “dig” into the system settings, you can find out the screen resolution through the Engineering Mode, which works for all Xiaomis, but you need to be careful – do not change other settings so as not to disrupt the phone!

Step-by-step:

Open the Phone app and type in the combination: ##4636## (some models may work ##36446337##).
You'll be taken to the Testing menu. Select Device Information.
Scroll down to the Display block – here will be the Resolution string with the current values.

🔹 What else can be checked in the engineering menu:

📶 Network signal and parameters of the communication module.
🔋 Battery condition (voltage, temperature).
🎤 Microphone and speaker test.

What happens if you change the parameters in the engineering menu?

Some settings (e.g. Band Mode for Networks) can cause communication loss or device overheating. If the phone starts to glittle after the changes, reset via Settings → System → Reset settings.

⚠️ Note: On devices with an unlocked bootloader or custom firmware, the engineering menu may be missing or not working correctly.

5. By phone model: Xiaomi permission table

If the phone is not turning on or you are just planning to buy, you can find out the screen resolution by model. Below is a table with the characteristics of popular Xiaomi, Redmi and POCO smartphones over the past 5 years.

Model	Year of release	Screen resolution	Type of matrix	Frequency of update
Xiaomi 14 Ultra	2026	3200 × 1440	AMOLED, 2K	120 Hz
Redmi Note 13 Pro+	2026	2712 × 1220	AMOLED, 1.5K	120 Hz
POCO F6 Pro	2026	3200 × 1440	AMOLED, 2K	120 Hz
Xiaomi 13T Pro	2023	2712 × 1220	AMOLED, 1.5K	144 Hz
Redmi Note 12 Pro	2023	2400 × 1080	OLED, FHD+	120 Hz

🔹 How to use the table:

🔍 Find your model in the first column.
📏 The third column indicates the native resolution (maximum for this matrix).
🔄 If the phone settings show a lower value (for example, 2280 × 1080 instead 2400 × 1080), So it's scaling.

Important: In models with Dynamic Refresh Rate support (such as Xiaomi 14), the screen refresh rate can automatically change from 1 Hz to 120 Hz depending on the content.

6. Through the computer: ADB-team-up

If you're familiar with ADB (Android Debug Bridge), you can get the screen resolution through the command line, which is useful if the phone doesn't respond to touch, but connects to a PC.

Instructions:

Install Platform Tools on your computer.
Turn on USB Debugging on your phone (Settings → About Phone → MIUI Version → 7 times tap the build number → Back to Additional → For Developers → Debugging by USB).
Connect your phone to your PC and type in the command line: adb shell dumpsys display
Find the mOverrideDisplayInfo bar – the current resolution will be indicated here.

🔹 Example of output for the Redmi Note 11 Pro+:

DisplayInfo{


...




appWidth=1080, appHeight=2400,




refreshRate=120.0,




...




}

⚠️ Attention: Use ADB It requires an unlocked bootloader on some Xiaomi models. If the command doesn't work, check if debugging is enabled. USB and whether drivers are installed.

💡

ADB-The method is suitable for diagnosing “bricks” (faulty phones) when the screen is not responding, but the device is determined by the computer.

Frequent questions about Xiaomi screen resolution

🔍 Why is the permission displayed in the settings 720p, The phone supports the full phone. HD?

You probably have UI zoom mode enabled. Go to Settings → Display → Font and Display Size and select Default or Small. Also check if Color Mode for the Visually Impaired is activated.

📱 How to find out the screen resolution on a switched off Xiaomi phone?

If the phone is not turning on, you can only determine the resolution from the model (see the table above) or through the label under the battery (on older models with a removable lid), the device box usually indicates only the screen diagonal, but not the resolution.

🎮 Does screen resolution affect performance in games?

Yes, but not as much as refresh rates. For example, on a POCO F5 with a resolution of 2400 × 1080, games will consume more resources than on a Redmi 9 with 1600 × 720. However, modern processors (for example, Snapdragon 8 Gen 2) easily cope with Full HD even in heavy games like Genshin Impact.

🔄 Can I change the screen resolution on Xiaomi?

On most Xiaomi native models, you can’t change the resolution, but you can enable interface scaling (see previous question). Except for custom firmware (like LineageOS), where DPI is sometimes available.

📊 Which resolution is better: Full HD or 2K?

It depends on the screen size: For 6.1-6.5 inches (e.g. Xiaomi 13), there is almost no difference between Full HD and 2K – the eye will not notice. For 6.7 inches or more (e.g. Xiaomi 14 Ultra), 2K gives a clearer picture, but increases the battery load. The optimal choice for most is 2400 × 1080 (Full HD+).
