Changing the screen resolution on Xiaomi devices can be necessary in a variety of situations, from optimizing performance in games to saving battery power or adapting the picture for a particular application. MIUI and Mi TVs TV In some cases, standard system settings simply do not provide direct access to the resolution change, and in others, improper actions can lead to poor image quality or even malfunction of the device.
In this article, we will analyze all possible ways to change the resolution on different types of Xiaomi devices: from budget Redmi smartphones to flagship Mi devices. 13 Ultra and Mi TVs TV Q2. You will learn how to enable hidden permission modes for games, why some models lack the option 1440p, And what if you change your settings, you get blurry screens, and we'll focus on Android compatibility. 13/14 and the HyperOS branded shell, which replaced MIUI into 2026 year.
Why change the permission of Xiaomi and when you really need it
Many users mistakenly believe that maximum screen resolution is always better, but in practice it is not: high detail requires more CPU and graphics accelerator resources, which leads to:
- ๐ Increased battery consumption โ especially noticeable on smartphones with AMOLED-screens where each pixel is illuminated separately.
- ๐ฎ Drawdowns FPS In games, even the flagship chipsets Snapdragon 8 Gen 3 or Dimensity 9200+ They may not be able to handle the rendering in 4K high-schedule.
- ๐ฑ Overheating of the device - constant operation at maximum resolution increases the load on the cooling system.
- ๐๏ธ Discomfort for vision โ on small screens (for example, Redmi Note 12 with a diagonal of 6.67) the difference between the two FHD+ and QHD+ It is almost invisible, but the eyes get tired faster.
On the other hand, the lower resolution is not always justified. For example, on Xiaomi TVs with a diagonal of 55" and above, the difference between the two is not always justified. 1080p and 4K And in some applications (like YouTube or Netflix), content automatically adjusts to native screen resolution, and artificially lowering the quality will only make the picture worse.
โ ๏ธ Attention: On devices with LCD-screens (e.g., screens, POCO X5 or Redmi 10C) Forced resolution change can lead to image artifacts, such as font blurring or a soapy effect, due to the peculiarities of the liquid crystal matrix.
When is a change in permission really helpful?
- ๐ฏ For gamers, the downgrade from 1440p before 1080p may increase FPS Genshin Impact, Call of Duty Mobile or PUBG on 15-30%.
- ๐ To save charge - on smartphones with AMOLED drop-off 20-30% Extends the Autonomous Work Time 1-1.5 hour.
- ๐ฅ๏ธ To connect to external monitors โ if your Xiaomi doesnโt support native-resolution monitors, you may need to manually adjust the monitor.
- ๐ For people with vision problems, zooming in (not to be confused with resolution!) makes icons and text bigger.
How to change the resolution on Xiaomi smartphones (MIUI/HyperOS)
Most smartphones Xiaomi, Redmi and POCO shelled MIUI 12-14 or the new HyperOS, there is no direct option to change the screen resolution in standard settings, this is due to the company's policy to ensure the optimal ratio of performance to image quality out of the box.
Method 1: Using the Developer Mode
The most reliable method is to activate the developer mode and manually set the desired permission.
โ๏ธ Preparation for change of permit
- Open the Settings. โ The phone.
- Find the item Version. MIUI (or HyperOS version) and tap it 7 times in a row, and you'll get a notification saying, "You've become a developer!".
- Return to the main settings menu and open a new Developer section (usually at the bottom of the list or in the Additional section).
- Scroll down to the Hardware Rendering Acceleration block and find the Minimum Width option (or Screen Resolution on some firmware).
- Turn off the option to disable permission redefinition (if active) and select the desired value from the drop-down list. 2400ร1080 on 2244ร1080 (downgrade ~7%).

- Clear the problem app cache in Settings โ Apps.
- Netflix and other streaming services may need to reset Widevine DRM:
โ ๏ธ Note: On HyperOS devices (e.g. Xiaomi 14), Widevine reset may result in security downgrading to a lower level of security. L3, What will block the playback of content in Full HD streaming services, to get back L1, You will need a complete reset of the device.
Problem 4: Phone or TV wonโt turn on after changing the resolution
In rare cases, incorrect settings can lead to a bootloop or a black screen, which usually occurs when:
- Set a resolution not supported by the display driver.
- Conflict with a custom core or firmware.
- Interrupting the process of changing the permit through ADB.
Decisions:
- For smartphones: press the power button + Volume up on 10-15 Then turn it on in recovery mode (Power) + Volume up) and perform a reset (Wipe) data/factory reset).
- For TVs, turn off power for 1 minute, then turn it on again. If the problem persists, press the Power Button. + Volume down on the remote for 5 seconds to reset screen settings.
