How to change the screen resolution on the Xiaomi phone: all the ways

Changing the resolution of the screen on Xiaomi smartphones is a challenge faced by users who want to optimize image quality, save battery power or adapt the display to specific applications. Unlike most Android devices where the resolution is fixed, many Redmi, POCO and Mi models allow you to manually switch between HD+ (720p), FHD+ (1080p) and adaptive mode. However, not everyone knows where these settings are hidden – especially after MIUI updates when the menu moves or changes.

In this article, we will look at all the options available to change resolution, from standard settings to hidden options in the engineering menu. We will focus on the nuances for popular models (for example, the Redmi Note 12 Pro+ or POCO F5), where the algorithm may differ. We will also find out why the option is blocked on some devices and how to get around it without risking warranty. If you notice that after the update the picture became less clear or the battery goes down faster, the resolution is most likely to blame automatically changed.

Why you may need to change the screen resolution

At first glance, high resolution is always a plus: the picture is clearer, the detail is better, but in practice, Xiaomi users have at least 5 reasons to experiment with the display settings:

• 🔋 Battery savings. FHD+ (1920×1080) consume 15–20% more energy than HD+ (1600×720). On weaker models (e.g. Redmi) 10A) difference 30%.
• ⚡ Performance enhancement: In games or resource-intensive applications like Genshin Impact, lower resolution gives you lower resolution. +5–10 FPS.
• 📱 Application adaptation: Some programs (e.g. emulators or old games) only work correctly when they are designed to be more responsive. 720p.
• 👁️ Comfort for vision: With a small screen (up to 6.2 inches), the difference between the two is HD+ and FHD+ It is almost invisible, but the eyes get tired less.
• 🔧 Diagnostics of problems: If the screen is washed or artifacts appear, testing at different resolutions helps to identify hardware defects.

It is important to understand that not all Xiaomi models support manual resolution change, for example, on the Redmi Note 11 (with a Snapdragon 680 processor), the option is available, and on the Redmi Note 11 (with a Snapdragon 680 processor). POCO M4 Pro (with Dimensity 810) is not available, the manufacturer blocks the feature to optimize power consumption. AMOLED-screens (e.g. Xiaomi 13 Ultra) change in resolution can affect color reproduction.

⚠️ Warning: On smartphones with an always-on display, changing the resolution can cause this feature to malfunction. → Always-On Display.

Method 1: Standard MIUI settings (for most models)

The easiest way is to use built-in options. MIUI. It works on most devices released after 2020 (e.g. Redmi Note 10 Pro, Xiaomi). 12T, POCO X5 Pro) The instruction is relevant to MIUI 14 and newer:

1. Open the Settings app (cog icon).
2. Go to the Screen section.
3. Select Screen Resolution (on some firmware it may be called Image Quality).
4. From the available options, choose: 📱 HD+ (1600×720) — cost-effectiveness; 🔍 FHD+ (2400×1080) — precision; ⚡ Auto – the system chooses the optimal resolution depending on the task.

Apply

Check the current battery level (recommended >30%)

Close all background applications

Turn off the power saving mode

Take a screenshot of the current screen settings (in case of rollbacks)-->

If you don't have screen resolution on the menu, your model doesn't support this feature at the software level, in which case try alternative methods (see the following sections). Also note that after changing the resolution, the system may suggest restarting the device - this is normal and will not affect the data.

Method 2: Engineering menu (for advanced users)

If standard settings do not work, you can try changing the resolution through the Engineering Mode, which is suitable for devices based on Qualcomm Snapdragon processors (for example, POCO F3, Redmi K50) and requires caution - incorrect actions can lead to display failures.

To open the engineering menu:

1. Open the Phone app.
2. Enter ##36446337## (for MediaTek) or #4636## (for Snapdragon).
3. In the menu that appears, select Hardware Testing → Display.
4. Find Resolution or Screen Resolution options and manually specify the values you want (e.g. 1080x2400).

⚠️ Note: In the engineering menu, some parameters are indicated by code values (for example, 1080p may be displayed as 1080_2400_60). Do not change other settings (such as Color Mode or Brightness) if you are not sure about their purpose – this can lead to incorrect screen operation.

After you change the screen, it can blink or go out for a second, which is normal. If the image becomes blurry or stripes appear, return the standard settings or restart the device. On some firmware (for example, custom LineageOS), the engineering menu may be missing or have a different interface.

Method 3: Use of ADB (for power users)

If previous methods failed, you can change the resolution via Android Debug Bridge (ADB), which is universal and works on any Xiaomi device, but requires a computer connection and basic command line knowledge, and the advantage of the method is the ability to set an arbitrary resolution, even if it is not provided in the standard settings.

Step-by-step:

1. Turn on Developer Mode on your phone: Go to Settings → About Phone. 7 times click on MIUI Version until the notification “You’ve become a developer” appears. Return to Settings → Additional → For Developers and enable USB Debugging.

Connect your phone to your PC through USB-cable (use the original cable for connection stability).

ADB Tools

cmd

Terminal

adb devices

(Your device should be displayed)

adb shell wm size 1080x2400

(Replace 1080x2400 with the desired resolution, such as 720x1600 for HD+).

adb reboot

To return the standard resolution, use the command:

adb shell wm size reset

adb shell settings put global hidden_api_policy 1

Then try again.-->>

Table: Supported permissions for popular Xiaomi models

Not all Xiaomi smartphones allow you to change the resolution manually, and the table below shows the data for popular models (relevant to MIUI 14/15):

If your model is not in the table, check the supported modes experimentally (via Settings → Screen). On new devices (for example, Xiaomi 14), the function can be hidden until stable firmware is released.

Frequent problems and their solutions

When changing the resolution, Xiaomi users often encounter typical errors, and consider the most common and ways to fix them:

• 🔄 The screen blinks or flickers after the resolution change, and the reason is that the mode you choose is not compatible with the refresh rate of the screen. Solution: return the standard settings or set the 60Hz frequency to the Settings. → Screen. → Frequency of update.
• 📱 There is no screen resolution in the settings. Possible reasons: Device does not support the function (see table above), custom firmware (e.g. Pixel Experience) is installed, where the option is disabled, Power saving policy is active (turn it off in Settings). → Battery).
• ⚙️ Once you restart, the resolution is reset, which is typical for devices with MediaTek processors (e.g., Redmi Note). 11). Solution: fix the settings through ADB Adb shell settings put global force_fps 1
• 🎨 The colors have become dull or unnatural. AMOLED-On screens (e.g. Xiaomi 12 Pro) the change of resolution can affect the color profile.Solution: reset the color settings in Settings → Screen. → Color mode.

⚠️ Note: On certain devices (e.g, POCO F4 GT) forced change of permit through ADB Or an engineering menu can block AdaptiveSync (adaptive refresh rate), in which case only a factory reset will help.

How to check the current screen resolution

If you are not sure what resolution is installed on your Xiaomi, there are several ways to find out:

1. Through MIUI settings: Go to Settings → Screen → Screen Resolution. Current mode will be ticked.

AIDA64

• Download AIDA64 from Google Play.
• Open the Display tab to indicate the current resolution (e.g., 1080×2400 pixels).
• Through ADB: adb shell dumpsys display In the output, find the line mCurrentDisplayInfo=DisplayInfo - there will be an active resolution.

On some devices (for example, Redmi Note 11 Pro+) the function returns after resetting the settings to the factory.
