Solution and optimization

Sometimes users are faced with a situation where the installed photo looks blurry or misaligned. This is often due to the discrepancy of the resolution of the picture with the proportions of the screen. Redmi 9 has an elongated format, and square or horizontal photos will be automatically cropped by the system. To avoid losing important details, use the built-in cropper when installing.

Another common problem is the presence of a black background around the image, which occurs if the aspect ratio of the image does not match the screen, in such cases it is recommended to use the "Blurring Background" function in the wallpaper editor (if available in your version of MIUI) or pre-process the photo in a third-party editor, adding blurred margins at the edges.

For the perfect display, always choose vertical images with a resolution of at least 1080 pixels on the short side.

Also worth mentioning is the impact of Do Not Disturb mode and screen switch schedules. In some versions of firmware, when active night mode, wallpaper can become darker or replaced with black to save energy. Check the settings in Settings → Lock screen → Do not disturb if you notice strange background behavior.
