Android screen resolution: where to find and how to change display settings

Screen resolution is a key parameter that affects the image quality of your Android device. It determines how clear texts, photos and videos are, as well as how applications adapt to the display size. But where exactly can I see the current resolution? And is it possible to change it without risk to the system?

In this article we will look at all the ways to check screen resolution on Android - from standard settings to hidden engineering menus. You'll learn how to determine the display's physical resolution (for example 2400×1080), as well as the current software resolution the system is using. We will separately consider the nuances for popular brands: Samsung, Xiaomi, Honor and others.

1. Standard method: through Android settings

The easiest method is to use the built-in system settings. It works on most devices, regardless of Android version or manufacturer. Here's how to do it:

1. Open the application Settings (gear icon).
2. Go to section About phone or About device (on some models — System → About phone).
3. Find item Device characteristics, Model information or Specifications.
4. Scroll down to the block Display —the physical screen resolution will be indicated here.

For example, on Samsung Galaxy S23 the path looks like this: Settings → Device maintenance → Phone information → Specifications. And on Xiaomi Redmi Note 12 — Settings → About phone → All characteristics.

⚠️ Attention: In some firmware (for example, Realme or Oppo), the physical resolution may be hidden. In this case, use alternative methods from the following sections.

If you need not the physical, but the current software resolution (which can be changed), look for it in the settings. display:

• 🔍 Settings → Screen → Screen resolution (on Samsung)
• 📱 Settings → Display → Screen size (on Xiaomi)
• 🖥️ Settings → System → Screen → Resolution (on clean Android)

2. Through the engineering menu (for advanced users)

If the standard settings do not show the resolution, you can use the engineering menu. This method is suitable for devices based on processors Qualcomm (most Xiaomi, OnePlus, Sony) and some Mediatek.

Instructions:

1. Open the application Phone.
2. Enter the code:

   ##4636##

3. In the menu that opens, select Device information or Hardware info.
4. Scroll to block Display -here the current resolution will be indicated (for example, 1080 x 2400).

On devices with a processor Mediatek (many Realme, Tecno, Infinix) try the code:

##36446337##

⚠️ Attention: Do not change the parameters in the engineering menu if you are not sure of their purpose. This may lead to malfunctions screen.

3. Using third-party applications

If the built-in methods did not work, third-party utilities will come to help. They will not only show the resolution, but also provide additional information about the display: pixel density (DPI), refresh rate, matrix technology.

Top 3 applications for checking resolution:

• 📊 CPU-Z - shows the physical resolution in the section Device → Display.
• 🔍 AIDA64 - detailed information about the display in Display → Resolution.
• 📱 DevCheck —a convenient interface with data about resolution, DPI and supported modes.

Example of display in CPU-Z:

Important: Some applications (for example, AIDA64) can show not only the current, but also the maximum supported display resolution. This is useful if you suspect that the system is running in a reduced mode.

4. data-i="108">If you are familiar with the developer tools, you can find out the screen resolution through

If you are familiar with developer tools, you can find out the screen resolution via ADB (Android Debug Bridge). This method is universal and works even on devices with limited settings.

Instructions:

1. Connect your smartphone to the PC and turn it on USB Debugging in Settings → For Developers.
2. Open the command line (Windows) or terminal (macOS/Linux) and enter:

adb shell dumpsys display

In the output, find lines:

• mCurrentDisplayRect=Rect(0, 0 - 1080, 2400) — current resolution.
• mBaseDisplaySize=Point(1080, 2400) —physical resolution.

To simplify, you can use the command:

adb shell wm size

It will display the current software resolution in the format Physical size: 1080x2400.

⚠️ Attention: Using ADB requires enabling developer mode. On some devices (for example, Huawei with EMUI 12+), this mode may be hidden - an additional code will be required to activate it.

5. Features for different brands

Manufacturers often modify Android by adding unique display settings:

Samsung (One UI)

• 🔧 Resolution changes depending on Settings → Screen → Screen resolution.
• 📏 Available options: HD+ (1600×720), FHD+ (2400×1080), WQHD+ (3200×1440) (on flagships).
• ⚡ On new models (for example, Galaxy S24) you can separately adjust the resolution for games via Game Launcher.

Xiaomi (MIUI)

• 🎨 Path: Settings → Screen → Screen size.
• 🔄 On some devices (for example, POCO F5) a mode is available Auto-resolution, which dynamically adapts to the content.
• 🛠️ In Settings → Advanced → Full screen you can hide camera cutouts, which affects the displayed area.

Honor/Huawei (EMUI/Magic UI)

• 🖼️ Resolution can be changed in Settings → Screen and wallpaper → Screen resolution.
• 📉 On budget models (for example, Honor X8) can only be accessed HD+.
• 🔒 On new devices (with Magic UI 7.0+) some display parameters are blocked without registering an account Huawei ID.

Enable developer mode (7 taps on build number)

Check the current resolution in CPU-Z

Compare with supported modes in Settings → Display

Make sure the refresh rate matches the resolution

6. How to change the screen resolution (and is it worth doing?)

Some users want to manually lower the resolution to save battery power or increase performance in games. However, this is fraught with consequences:

Pros:

• ⚡ Increased battery life (by 5-15%).
• 🎮 Increased FPS in games (by 10–20% on weak chipsets).
• 👁️ Reduced eye strain during prolonged use.

Cons:

• 🔍 Loss of clarity of text and images.
• 🚫 Some applications may be displayed incorrect.
• 🔋 Risk of overheating with incorrect settings (if the refresh rate is not synchronized with the resolution).

If you do decide to change the resolution, do it through the settings (as described above) or using ADB:

adb shell wm size 720x1600

To return the standard resolution, use:

adb shell wm size reset

⚠️ Attention: On some devices (for example, Google Pixel with pure Android), forcing a resolution change via ADB may cause the interface to crash. In this case, only resetting the settings will help.

7. Frequent problems and their solutions

Sometimes users encounter incorrect resolution display. Let's look at typical situations:

Problem 1: The resolution is lost after the update

After installing a new version of Android or firmware, the screen may be displayed in low resolution. Solution:

1. Go to Settings → Display → Resolution and select the maximum value.
2. If the item is missing, reset the screen settings: Settings → System → Reset settings → Reset screen settings.
3. On Samsung try disabling Adaptive refresh rate in the display settings.

Problem 2: Applications do not support the current resolution

Some games or apps (for example, Genshin Impact or AutoCAD) may refuse to launch if the screen resolution is not standard. Solution:

• Temporarily return the standard resolution through the settings.
• Use compatibility mode (if available in the application settings).
• On Xiaomi enable Full screen mode for a specific application in Settings → Applications → Full screen mode.

Problem 3: Resolution does not change

If changing the resolution is not available in the settings, the reasons may be as follows:

• The manufacturer has blocked this function (relevant for Huawei after sanctions).
• The device uses custom firmware with limited settings.
• Energy saving mode is enabled, blocking display changes.

In this case Only firmware that supports changing the resolution or using ADB (if supported) will help.
