Modern smartphones like the Xiaomi Redmi Note 9 Pro have gorgeous FullHD+ screens that can display the smallest details of an image. Standard images preinstalled by the manufacturer often seem boring and do not reflect the individuality of the owner, which is why many users are looking to personalize their device, starting with the desktop and lock screen.
The process of changing the background is not just about changing the image, but the ability to change the perception of the MIUI interface. In this article, we will examine in detail all the available methods, from embedded tools to third-party applications with high detail, you will learn how to activate dynamic effects and where to find really high-quality source codes.
It is worth noting that choosing the wrong format or source of a file can lead to lower image quality or increased battery consumption. So it is important to understand the difference between static graphics and live animations. We will look at the technical nuances that will help avoid common customization errors.
Preparation of the device and choice of the source of graphics
Before you start installing, you need to make sure that your device is ready to work with new files. Redmi Note 9 Pro supports a wide range of formats, however, for best results, you should prefer images with a resolution of at least 1080x2400 pixels. Using low-quality images will lead to artifacts and βgrainβ on the display.
There are many sources for downloading content: Official repositories offer proven options, but often limited in choice; third-party resources can provide more unique solutions, but require caution when downloading; It is important to check files for malicious code before installing.
- π± Official theme store MIUI Themes is a secure but sometimes paid source.
- π Specialized sites with HD-Wallpaper β requires manual loading into the gallery.
- π¨ Aggregator apps β automatically select images to taste.
- πΎ Local Memory β Using your own photos in high resolution.
Special attention should be paid to the free space in the memory of the smartphone. caching heavy graphics files can take a significant amount if not regularly cleaned, it is recommended to free up several gigabytes in advance for comfortable operation of the system and new applications.
Use of the built-in Themes application
The easiest and most reliable way to change your visual style is to use the Theme System App, which is deeply integrated into the MIUI shell and ensures that all elements are compatible, and you just need to find the appropriate icon in the Tools folder or search it.
Inside the app, go to the Wallpaper tab, which features a huge catalog of images, and it lets you filter content into categories like nature, abstraction, cars, space, and more, and some collections are labeled with a Pro icon, which means they're paid or they need to subscribe.
β οΈ Note: When downloading themes from third-party regions (such as India or Indonesia) through a region change in settings, make sure you return the original settings after download so as not to disrupt the banking applications.
Once you have selected your favorite option, click Download and then Apply. The system will suggest that you install the image on the lock screen, desktop or both screens at the same time, which is the most stable method and does not require root rights.

Installation of live wallpaper and video backgrounds
Dynamic images add life to the smartphone, turning the screen into a window into a different world. On the Redmi Note 9 Pro, you can install both standard live wallpaper from Google and specialized video backgrounds through the Themes app. However, it is worth remembering that constantly rendering animation increases the load on the processor.
Video wallpaper installation often requires special files with the.mp4 extension or proprietary theme packages. There is a separate section in the theme store called "Video" where you can find animated screensavers. Once downloaded, they are automatically available in the background selection menu.
Technicians say that using complex animations can reduce battery life by 10-15%, and if you are critical to energy efficiency, you should choose a high-quality static image or simplified animation.

Configure wallpaper from the Gallery and third-party files
Often, users want to see their own photos or downloaded art on the screen. This is done using the standard Gallery app. Open the image you want, click on the three dots in the upper right corner, and select Set as wallpaper.
The Redmi Note 9 Pro screen has a 20:9 aspect ratio, so vertical photos are perfect, and horizontal ones will have to be cropped or scaled. Move the frame to select the composition.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Permission | 1080 x 2400 px | Clearness of image |
| Format | JPG / PNG | Compatibility |
| File size | 10MB | Loading speed |
| Color model | sRGB | Color rendering |
It is important to consider that system icons can overlap important image details, so when framing, leave the center part free or choose abstract backgrounds where the parts do not have strict geometry, which will preserve the readability of the interface.

Use the βEnlarged Wallpaperβ function in the screen settings so that when you flip through the desktops, the image smoothly shifts, creating a parallax effect.
Quality problems and their solution
Sometimes the image looks blurry or the colors appear faded after installation, which may be due to aggressive file compression by the system or an incorrect color profile. The Redmi Note 9 Pro screen settings have Standard and Saturated modes, which can be switched between to correct color reproduction.
If the wallpaper is floating or has compression artifacts, try converting the source file to PNG before installation. This format uses lossless compression, which is critical for graphics with gradients and text. Conversion can be done on a PC or through online services.
In rare cases, the problem lies in the launcher's cache. Clearing the Desktop application's data (not to be confused with Gallery) can help, but it will reset the location of the icons. Make a backup before such manipulations.
β οΈ Warning: Do not use accelerator applications to compress wallpaper before installation. They often degrade the picture quality to save space, which is on a high-resolution screen. DPI looks miserable.
