How to disable “Optimized for Full-screen” on Xiaomi devices

If you’re faced with “Optimized for Full-screen” on your Xiaomi device’s screen — TV, smartphone, or tablet — and want to return to standard display, this article will help you understand the reasons and ways of doing so. This optimization is often activated automatically after updating your firmware, installing new apps, or changing screen resolutions. In some cases, it improves the user experience, but often leads to cropping the interface, hiding controls, or distorting image proportions.

Xiaomi is implementing this feature to adapt content to modern bezel-free displays, but not all users like the result. For example, in Android TV or Google TV, full-screen mode can crop subtitles, hide navigation bars in games or interfere with work with office documents. On smartphones running MIUI, a similar problem manifests itself in applications where important buttons are outside the visible area. Next, we will look at how to turn off this optimization on different types of devices without resorting to radical measures like resetting.

Why does the word “Optimized for Full Screen” appear?

The full-screen optimization message is not a mistake, but rather a notification to the system that the content is adapted to the current display settings, and the reasons for its occurrence may be as follows:

• 📺 Automatic zoom setting after firmware update (especially relevant for Xiaomi Mi TVs) TV or Redmi Smart TV).
• 🔄 Changing screen resolutions manually through Settings → Display.
• 🎮 Running games or applications that use non-standard aspect ratios (e.g. 16:9 instead of 21:9).
• 📱 Activation of Full Screen in Settings MIUI (smartphone).
• 🖥️ Connecting an external monitor or projector with a different resolution.

On Xiaomi TVs, this feature is often associated with AI Master for Picture technology, which automatically adjusts the image to the content. In smartphones, the “Advanced Full-screen Mode” option in the display settings can be to blame. It is important to understand that disabling optimization is not always possible at the level of an individual application – sometimes a global change in system settings is required.

Ways to turn off full-screen mode on Xiaomi TVs

If the label appears on a Xiaomi Mi TV 4/5, Redmi Smart TV or other model on Android TV, try the following methods: Start with the simplest and move on to the more complex if the problem is not solved.

Method 1: Rescaling the image

The quickest way is to adjust the scale manually:

1. Open Settings (cog in the upper right corner of the main screen).
2. Go to Display and Sound → Image → Image Scale.
3. Select Screen Size or 4:3 (if the content is cropped on the sides).
4. Turn off the AI Master for Picture option (if available).

If the image scale item is not available, try an alternative path:

Settings → Device → Screen → Screen → Standard (instead of “Stretch” or “Auto”)

Method 2: Resetting image settings

If manual adjustment does not help, reset the image settings to factory:

Turn off the TV from the internet (to avoid automatic updates)

Write down the current brightness/contrast settings

Check that there are no important data in the memory of the TV (screenshots, recordings)

Connect the remote to the TV (in case of hanging)

-->

1. Go to Settings → Display and Sound → Additional settings → Reset image settings.
2. Confirm the action. After the reboot, check if the inscription has disappeared.

1. Open Settings → Applications → Application Management.
2. Select a problem app (like YouTube or Chrome).
3. Slip to Full Screen Mode (or Display).
4. Select Standard instead of Full Screen or Extended.

If the option is not available, try another method.

Settings → Additional → For Developers

If previous methods have not worked, reset the display settings:

1. Go to Settings → Display → Additional settings.
2. Select Reset Display settings.
3. Confirm the action and restart the device.

To prevent the problem from returning after a reboot or update, follow these tips:

• 🔄 Check your settings regularly → Update the system and postpone the installation of new versions of the software, if users mention bugs with display in reviews.
