How to set up a zoom on a Xiaomi TV

Owners of modern Xiaomi TVs and Mi Box consoles often face the need to rescale the image, which can be caused by the desire to see the small details in the application to view photos, the need to remove the black bars at the edges of the screen, or simply the need to adjust the picture to specific content. The zooming function, or zooming, in the Android TV system is not always obvious, and many users are lost in the settings menu.

Unlike computer monitors, where font and window sizes are controlled through Windows or macOS, televisions are different. It is important to distinguish between software zoom (digital zoom) and physical fitting of the image to the matrix. Incorrectly configured can cause important interface elements, such as time or navigation buttons, to be outside the visible area of the screen. Understanding these differences is the first step to fine-tuning.

In this guide, we’ll look at all the ways to scale, look at both the standard Android TV system and the hidden features of remotes that are often ignored, learn how to adjust the aspect ratio for old movies and how to use your smartphone as a remote for more accurate zoom control in the gallery.

The main image settings in the TV menu

The first place you should go is the standard settings menu for your TV. MIUI for TV or pure Android TV provides the basic tools to correct your picture. Most often, the problem is solved by changing the aspect ratio, which is visually perceived as zoom or no zoom. To access these settings, you need to click the settings button on the remote or go to the profile section.

Inside the menu, you'll find the display section, and depending on the firmware version, it might be called Screen and Sound, Image, or Display Settings, and that's where the key feature, Aspect Ratio, is located, and by switching its values, you can stretch the image to the whole screen, or you can compress it by adding fields.

⚠️ Warning: Changing the aspect ratio to 16:9 for 4:3 content will cause a massive distortion of proportions, with people on screen becoming unnaturally wide and round objects turning into ovals.

If standard presets don’t work, look for Screen Mode or Format. Some Xiaomi TVs have Auto-Tune in, which tries to determine the best zoom mode for itself, but for manual zoom control in apps (such as a browser or gallery), these settings may not be enough, as they affect the entire video stream globally.

• 📺 Click the “Menu” or “Settings” button on the remote control.
• ⚙️ Go to the Settings section → Screen and sound (or just an image).
• 🖼️ Find the aspect ratio and try the 16:9, 4:3, or Original options».
• 🔄 Check the availability of the "Auto" mode for automatic fitting of the picture.

Use of the Loop function and special features

The Android operating system that powers Xiaomi TVs has powerful tools for people with disabilities, such as Magnification, which allows you to zoom in on a specific area of the screen, which is ideal for looking at small details, text in documents or photos without losing quality to the rest of the image.

Activating this function requires going to the deep settings of the system. You need to find the "Accessibility" section. There is the "Loop" item. Once this option is turned on, a magnifier icon may appear on the screen or the behavior of the remote buttons may change. Usually, the increase is made by quickly pressing the power button of the remote three times or through a combination of keys, if this is provided by a specific firmware modification.

When the function is activated, zoom control is done in the following way: double-tapping the screen (if the remote is touch-sensitive) or using navigation buttons to move the enlarged area. This doesn't just stretch the picture, as in the image settings, but creates a virtual magnifying glass, which is especially useful when viewing maps or diagrams through a browser on a TV.

It's important to understand the difference between this feature and the normal zoom of a camera or gallery. The system magnifier runs on top of all applications. That means you can turn it on, open any content, and it becomes available for detailed study, but it's worth remembering that when you zoom in, you can experience a loss of clarity, because the TV just stretches the existing pixels.

• ♿ Go to Settings. → System system → Special facilities.
• 🔍 Find and turn on the Loop (Magnification).
• 🖱️ Use triple pressing the select button (OK) or the assigned key to activate.
• 📐 Move through the enlarged image with the arrows on the remote.

Customization of zoom in the applications Gallery and Browser

Often users are looking for a way to customize the zoom for viewing photos or web pages. Unlike system settings, this is implemented inside the applications themselves. In the standard Xiaomi Gallery or Google Photos, the zoom is done by the remote buttons. Usually, the Up and Down buttons or special "+" and "-" keys (if they are on the remote) are responsible for approximation and deletion.

In web browsers like Chrome or Puffin TV, the situation is similar to a computer one, and the page size can be changed through the browser's settings menu, but on TV, it's not easy to do that, and a more effective way is to use key combinations if they're emulated by a remote control, or, more often, to control it through a remote control application on a smartphone.

For those who often work with documents or drawings on a large screen, there is a caveat: some applications do not support native remote zooming. In such cases, the mouse mode helps. If your remote supports cursor control (gyroscopic remote or Mi Remote application), you can pinch the scroll wheel or use the on-screen cursor to more accurately position the zoom area.

There's also the possibility of installing third-party image viewing apps that have more flexible zoom settings, like X-plore or specialized viewers that allow you to not only zoom in, but also rotate it, change contrast on the fly, which makes the TV a powerful tool for displaying visual content.

Control via Mi Remote app on your smartphone

One of the most effective ways to fine-tune zoom, especially in apps that don't have a user-friendly remote interface, is to use a smartphone. The Mi Remote app (or the built-in "Remote" feature in Xiaomi phones) turns the phone's screen into a touchpad. This gives the advantage of precision that is not available when controlling buttons.

When you connect your phone to your TV via Wi-Fi, you can control your cursor. In touchpad mode, you can pinch-to-zoom with two fingers on your smartphone screen to zoom in on your TV, and this works in many multi-touch emulation applications, including maps, browsers, and some media players.

In addition, the app often provides a full TV interface, including hidden menus. You can quickly reach screen resolution settings or start color calibration without flipping through long menus with a remote. To customize zoom in specific applications (such as Zoom or Skype on a TV), smartphone control is almost an allerative option for comfortable work.

⚠️ Warning: Make sure your smartphone and TV are connected to the same Wi-Fi network. If the devices are on different subnets (e.g., one in the guest, the other in the main), the remote connection will not be established.

Also worth mentioning is the Cast feature: You can stream your smartphone screen to your TV and control zoom directly on your phone. The image on the TV will repeat all actions, including thumb zooming, which is ideal for presentations or viewing photo albums from a mobile device on a big screen.

Solving framing and black fields problems

A common problem that users mistake for zooming is that the signal is not properly cropped. The image may not fill the entire screen, leaving black fields around the perimeter. This phenomenon is called Overscan, or, conversely, insufficient scanning. In Xiaomi TVs, this problem is solved by adjusting the screen format.

The image menu often has a Just Scan, Screen Size, or Original mode, which causes the TV to display the picture as a pixel, without cutting edges. If it doesn't, you can try changing the output resolution in the system settings. Sometimes the TV defaults a low resolution (like 720p) that stretches into a 4K matrix, creating the illusion of poor quality and incorrect size.

For advanced users connecting external devices (laptops, consoles) via HDMI, it is important to adjust the signal source itself. If the computer is scaling the interface 125% or 150%, on the TV it will look like a huge but blurred zoom, you need to bring the zoom settings in Windows or macOS to 100% for correct display.

💡

The correct solution to the problem with the fields on the screen is not software zoom, but the correct configuration of the scan format (Aspect Ratio) in the TV menu.

Specifics of setting up Mi Box and Android TV consoles

If you're not using the TV system, but an external set-top box, the Mi Box S or Mi Stick, the logic of the setup changes, and the set-top box is the only one that displays the image, and the TV is the monitor, in which case the zoom is set up exclusively through the Android TV set-top box interface.

In the set-top box settings (Settings → Device settings → Screen and sound), you have the option "Screen Resolution" available, and you need to choose the mode that physically supports your TV, and you also have the "Screen Calibration" setting that helps you adjust the boundaries of the image if they go beyond the visible zone, which is analogous to the format adjustment function, but at the signal source level.

For consoles, installing launcher applications that allow more flexibility to manage the interface is important. Some launchers have their own settings of the scale of icons and fonts, which affects the overall perception of the system’s “zoom.” If the standard interface seems too large or small, changing the launcher can solve the problem without digging deep into system files.

💡

When using the Mi Box, always use a high-quality HDMI cable. Cheap cables may not transmit the 4K signal correctly, which will automatically reduce the resolution, and the picture will become less clear, requiring artificial magnification.

Do not forget the possibility of installation APK-Applications such as Set Resolution (require root rights or ADB) They allow you to force you to set the right resolution and refresh rate if the standard settings don't work, which is a last resort, but it's effective for older TVs with custom arrays.
