How to increase video on Xiaomi phone: from gestures to hidden settings MIUI

Are you trying to watch a video on Xiaomi, but the picture is too small and finger zooming doesn't help? Or is the image cropped around the edges and black stripes spoil the viewing experience, POCO Mi – especially when viewing content with a non-standard aspect ratio (for example, 21:9 or 4:3 on the screen 20:9). In this article, we will discuss all the working ways to increase video on Xiaomi phones, including hidden settings. MIUI, gestures and third-party instruments.

It's important to understand that zooming in can mean different things: someone wants to just zoom in (close details), and someone needs to stretch the video to the full screen without black bars. We'll look at both basic methods to advanced tricks that work even on older models like the Redmi Note 8 Pro or the new flagship Xiaomi 14 Ultra.

1. Basic ways to increase video in Xiaomi player

Let’s start with the simplest – built-in functions of the standard player MIUI (Or Google Photos, if you're watching the video from there. These methods work on all models, from Redmi. 9A Xiaomi 13T Pro and do not require additional applications.

The most obvious way is to spread the screen with two fingers while viewing.

• 🔍 The zoom gesture doesn't work in all players. MIUI Scaling is supported, but not on YouTube or TikTok.
• 📏 After zooming in, the video may crop at the edges – this is normal, as you’re actually zooming in on the center of the frame.
• 🔄 To reset the scale, with two fingers, squeeze the screen or touch the magnifying glass icon (if it is in the player interface).

If the gesture does not work, check the player settings:

1. Open the video in the Video app (film icon on the desktop).
2. Slip on the screen to make the controls appear.
3. Press three points (⋮) in the upper right corner and select the player settings.
4. Activate the zoom gesture option (if you have one in your version) MIUI).

⚠️ Note: On some models (e.g, POCO X3 Pro) zoom gestures are disabled by default to save resources. If the option is not available in the settings, update the Video app via Google Play.

2. stretch the video to the full screen without black bars

Black bars on the sides of a video (so-called letterbox) appear when the aspect ratio of the video is not the same as the ratio of the phone screen. For example, a 16:9 video on a 20:9 screen will have small margins, and 4:3 content (like in older films) will have wide ones.

To get the stripes out, you need to stretch the video to the size of the screen, and you can do this in a number of ways:

Method 1: Player settings MIUI

• 🎬 Open the video in the standard Video app.
• 🔧 Slip on the screen, then tap on the icon. ⚙️ Settings (or three points).
• 📺 Select the aspect ratio → Stretching or filling the screen.
• 🔄 If the picture is distorted (for example, circles have become oval), go back and select the size of the screen.

Method 2: Hidden function "Adaptive display"

V MIUI 12/13/14 There's a hidden option that automatically adjusts the video to the screen to activate it:

1. Go to Settings → Display.
2. Scroll down and tap the additional display settings.
3. Find the Adaptive Display item and turn it on.
4. Return to the player and check if the black stripes have disappeared.

This feature does not work on all models – it is not available on budget smartphones like Redmi. 10A, But there is on the flagships Xiaomi 12S Ultra or POCO F4 GT.

💡

If the video starts to "brake" after stretching, try to reduce the resolution in the player settings. MX Player is an option Decoding software - it reduces the load on the processor.

3. Third-party players with extended zoom functions

If standard methods don't work, it's time to turn to third-party apps that offer more scaling options, including manual aspect ratio adjustment and frame-by-frame zoom.

Top.-3 Player for Xiaomi, which can properly increase video:

• 🎥 MX Player – supports zoom gestures, hardware/software decoding, and can even correct distortions when stretching.
• 📺 VLC — It allows you to change the aspect ratio manually (for example, set 18:9 for 16:9 video).
• 🔍 BSPlayer – there is a Pan & Scan function that allows you to “cut” the desired part of the frame and stretch it to the full screen.

How to set up MX Player for perfect scaling:

1. Install the player from Google Play.
2. Open the video, then double tap the screen – this will turn on zoom mode.
3. To capture the scale, go to Settings. → Video → Size and select Default: 100%.
4. To stretch without distortion, activate Save proportions.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 11) MX Player can conflict with system player. If the video is not playing, try in the settings MX Player to change decoder to SW Decoder.

Install the player from the official store|Enable zoom gestures in the settings|Select a hardware decoder (if the video slows down)|Turn off the "Switch" if the picture is not rotated correctly|Check the scale settings in the "Video" section"-->

4. Correct video cropping as zoom in

One of the most common problems in zooming is cropping the edges of a video, for example, when watching a movie with subtitles, they can "go" off the screen, or important details of a frame (for example, a clock in the corner) become invisible, and this is solved by adjusting the display area.

Here's how to bring back the cropped edges:

Method 1: Adjustment to MX Player

1. While watching the video, make a double tap to activate zoom.
2. Holding your finger on the screen, drag the picture in the right direction - this will shift the display area.
3. To fix the position, touch the icon. 🔒 (lock.

Method 2: Screen settings in MIUI

If the video is cropped even without zooming, the problem may be in the display settings:

1. Go to Settings → Display → Screen size.
2. Choose Standard (if it is Reduced or Large).
3. Check if Reading mode is activated or with one hand – these can affect the display.

In the models with AMOLED-screens (e.g. Xiaomi) 12T or POCO F5) Sometimes it helps to reset the color settings:

Settings → Display → Color scheme → Reset to factory

5. Increase video through editing (for permanent effect)

If you want to permanently zoom in on your video (for example, to send it to a friend or save it to a zoom gallery), you’ll need to use editors. This is true for videos that you shoot yourself on Xiaomi and want to use later with zoom effect.

The best video editing apps on Xiaomi:

• 🎬 CapCut – allows you to crop and zoom video without loss of quality, there is a Ken Burns feature for smooth zoom.
• 📱 InShot – a simple editor with the option Scale and manually adjust the aspect ratio.
• 🖥️ KineMaster – professional tool with the ability to overlay multiple layers of zoom.

Step-by-step instructions for CapCut:

1. Import the video to the app.
2. Slip on the clip on the timeline, then select Cut.
3. Enable the option Free zoom and with two fingers enlarge the desired area.
4. To add the effect of movement, go to animation → Scale and customize key personnel.
5. Export the video in maximum resolution (select the video) 1080p or 4K, if maintained).

⚠️ Attention: When you zoom in on a video editor, the quality may deteriorate, especially if the original file was low resolution. 720p after-zoom 1080p To avoid this, shoot video on Xiaomi in maximum resolution (4K flagship 1080p budget-based).

💡

Video editing is the only way to permanently fix zoom. All other methods (gestures, player settings) work only while watching and are not stored in the file.

6.Problems with increasing video on specific Xiaomi models

Some Xiaomi smartphones have unique bugs or limitations associated with video zooming. Let's take a look at the most common cases and their solutions.

Redmi Note 10 Pro / POCO X3 Pro: Video slows down at zoom

On these models with a Snapdragon processor 732G When you zoom in on the standard player, you can see lags:

• 🔧 Install. VLC Player and in the settings select Hardware acceleration: Disabled.
• 📉 Reduce the resolution of the video in the player settings (for example, with 1080p before 720p).
• 🔄 Update the firmware to the latest version MIUI (bug MIUI 13.0.4 and newer).

Xiaomi Mi 11 / 11T Pro: Black stripes remain even after stretching

On the flagships with AMOLED-Sometimes the function of stretch does not work due to conflict with AdaptiveSync technology:

1. Go to Settings → Display → Update frequency.
2. Select a fixed value (e.g. 60 Hz instead of Auto).
3. Return to the player and repeat the stretch.

Redmi 9 / 9A / 9C: There is no scaling option in the player

On budget models, the standard player MIUI often lacks zoom functions:

• 📥 Install. MX Player or VLC Google Play.
• 🔄 Use Developer Mode for Forced Scaling (see next section).

7. Advanced methods: ADB and the developer settings

If the standard methods did not work, you can try to force change the display parameters through the developer settings or ADB-These methods are suitable for experienced users and require caution.

Method 1: Change the screen density (DPI)

Reduce the value DPI It's going to make the system display a bigger video:

1. Activate the developer mode (see spoiler above).
2. Go to Settings → Additional → For developers.
3. Find the minimum width (or DPI) and reduce the value on 20-30 units (e.g. with 440 before 410).
4. Reboot the phone.

⚠️ Consequences: Change DPI It's going to affect the size of all the interface elements, not just the video. To get it back, reset the developer settings.

Method 2: ADB-commands for forced scaling

With help. ADB You can make the system stretch the video even if the player doesn't support it. USB-cable.

Steps:

1. Connect Xiaomi to your PC and activate Debugging USB.
2. Open the command line (cmd) and enter:

adb shell settings put global force_fullscreen true

This command will cause the system to ignore the aspect ratio of the video. To reverse the effect, do:

adb shell settings put global force_fullscreen false

⚠️ Attention: Misuse of the right ADB Don't change other settings unless you're sure they're there. For example, the adb shell wm size reset will reset the screen resolution to the factory settings.
