You have included your favorite movie on Xiaomi Mi TV or Redmi Smart TV, But instead of getting caught up in the story, what's happening to you is that there's an annoying white bar on the edge of the screen, and that's a problem that happens to TV owners and people who live in the city. TV-Xiaomi boxes regardless of the model โ whether it is a budget Redmi TV A55 or the flagship Mi TV Q2 75.โ White stripes may appear on top, bottom or sides, spoiling the viewing experience.
80 percent of the time, the scaling settings are wrong, but sometimes the root of the problem goes deeper โ firmware, format incompatibility, or even the hardware limitations of the panel. In this article, we'll look at all the possible causes of whitewashing and give you step-by-step instructions to fix it, learn how to fix the problem through the TV menu, update the firmware, configure external devices, and even manually calibrate the screen โ without going to the service center.
Why does the white strip appear on Xiaomi TV?
Before you start fixing, itโs important to understand whatโs causing the defect. The white bar on Xiaomiโs screen isnโt a matrix breakdown (99 percent of the time), but a video signal malprocessing. Here are the main reasons:
- โ๏ธ Incorrect zoom mode โ the TV crops or stretches the image, leaving empty space.
- ๐บ Permission incompatibility โ a source (prefix, computer, satellite receiver) transmits a signal in a resolution that TV cannot correctly represent.
- ๐ Firmware errors - bugs in MIUI TV Android TV, Especially after automatic updates.
- ๐ฌ Movie format โ some files (e.g., 21:9) require manual configuration.
- ๐ Problems with HDMI-cable โ damaged or poor quality cable can transmit a signal with artifacts.
I wonder what Xiaomi is doing. TV Box (such as Mi Box S or Mi) TV Stick) white bars appear more often when viewed through apps like Kodi or VLC, Whereas on embedded TVs, the problem is usually external, and it's also been observed that the bandwidth is more common when connected through a network. HDMI ARC or when using Game Mode.
If the band appeared suddenly, remember what you changed before: update the firmware, connect a new device or change the settings of the image?
Method 1: Change the zoom mode (Zoom)
The easiest and most effective solution is to change the display mode. There are several pre-installed zoom options on Xiaomi TV, and often the band disappears after switching between them.
How to do this:
- During the playback of the film, press the Menu button on the remote.
- Select the Image icon (or Picture in English firmware).
- Go to Screen Mode or Aspect Ratio.
- Try every mode you can: Auto, the TV scales itself. 16:9 is the standard ratio for most movies. 4:3 for older movies or TV shows. Zoom, zooms in by cutting edges. Just Scan or Direct, shows a picture without zooming (better for 4K).
Usually, the band goes missing in Just Scan or 16:9 modes. If you watch a movie with black stripes (like 2.35:1), try Zoom 1 or Zoom 2, which will cut the black fields, but can also remove the white stripe.
โ๏ธ Verification of scaling modes
โ ๏ธ Note: On some Xiaomi models TV (Like Mi. TV 4S 55") Just Scan can be hidden. To activate it, first set 16:9, then go back to the menu - sometimes the item appears after changing the mode.
Method 2: Configure an external device (prefixes, PC, receiver)
If the white bar only appears when connected via HDMI (for example, from the Xiaomi Mi Box, gaming console or computer), the problem may be on the source side of the signal. Many devices independently adjust the output resolution, and sometimes it does not match the optimal for your TV.
Here's what we need to do:
Xiaomi TV Box (Mi Box, TV Stick)
- ๐ฆ Go to Settings. โ Display and sound โ Screen resolution.
- Choose Auto or manually set the resolution that supports your TV (e.g. 3840ร2160@60Hz for 4K).
- Turn off the option Automatic change frame rate if it is active.
For computer (Windows/macOS)
- ๐ป On Windows: Right-click on the desktop โ Screen parameters โ Additional screen parameters โ Establish the recommended permit.
- ๐ On Mac: System settings โ Monitors โ Select the default scale for (model) TV).
- ๐ Try another one. HDMI-port on the television (for example, HDMI 2.0 instead HDMI ARC).
For game consoles (PS5, Xbox, Nintendo Switch)
- ๐ฎ On PlayStation 5: Settings โ Screen and video โ Permission of withdrawal โ set up automatically.
- ๐ค On Xbox Series X|S: Settings โ General. โ Settings TV display โ Permission โ choose 4K UHD (if maintained).
If after changing the resolution, the image became blurred or artifacts appeared, return the previous settings and try another one. HDMI-cable (preferably certified by High Speed) HDMI or Ultra High Speed HDMI for 4K).

If you connect a PC, try manually setting a 50Hz refresh rate instead of 60Hz screen โ this sometimes solves the bandwidth problem when watching PAL movies.
Method 3: Update the TV firmware
Scaling errors are often caused by firmware bugs. Xiaomi regularly releases updates for its TVs that fix such problems. For example, the firmware for Mi TV Q1E version 1.6.65 fixed a white-bar bug when playing content in HDR10+.
How to update firmware:
- Open Settings โ About TV โ Update system.
- Click Check for updates.
- If a new version is available, confirm installation. The TV will restart.
If the automatic update does not work:
- ๐ Download the latest firmware for your model from the official Xiaomi Support website.
- ๐ Copy the file (usually with the.zip or.pkg extension) onto a flash drive formatted into a file. FAT32.
- ๐ Connect the flash drive to the TV, then select Local Update from the update menu.
After updating, reset your image settings to factory: Settings โ Image โ Reset. This will help avoid conflicts between old parameters and new firmware.
| Model Xiaomi TV | The Last Stable Firmware (May 2026) | Famous bugs with stripes |
|---|---|---|
| Mi TV Q2 75" | 1.8.72 | Dolby Vision on Netflix |
| Redmi TV A55 | 1.5.43 | Strip from the bottom at 1080p@50Hz |
| Mi TV P1 65" | 1.7.61 | The strip on the left in Game Mode |
| Xiaomi TV Box S 2nd Gen | 2311 (Android 11) | Strip in Kodi at 21:9 |
โ ๏ธ Note: If the band has not disappeared after the update, and new artifacts have appeared (for example, green pixels or flickering), roll back the firmware. 4PDA Install it through Local Update.
Method 4: Manual screen calibration (for advanced users)
If standard methods donโt work, you can manually adjust the position of the image, which is suitable for models on Android TV (for example, Mi TV Q1E or Redmi Smart TV X), where engineering settings are available.
Instructions:
- Turn on Developer Mode: Go to Settings โ About TV. Find the Build Number and click on it 7 times in a row. Go back to Settings and a new Developer section will appear.
USB debugging
ADB
TV Settings
Google Play
ADB-team
For adjustments through ADB:
adb shell wm overscan 0.0.0.0 # Resetting of cropping
adb shell wm overscan 0.5.0.0 # Shift the image down by 5 pixels (if the band is on top)
adb shell wm overscan 0.0,0,5 # Shift the image up by 5 pixels (if the band is below)The values of 0.5.0.0 are left,top,right,bottom. Experiment with numbers (e.g., 0.10.0.0.0) until the band disappears. To keep the changes after the reboot, use:
adb shell settings put global overscan_custom 0,5,0,0What to do if ADB is not connected?
For models on MIUI TV (not Android TV), the engineering menu opens through a service remote or a combination of buttons. For example, on Mi TV 4A:
- Turn off the TV.
- On the remote, hold Menu + Volume Down and hold for 5 seconds.
- Turn on TV and the service menu will open.
- Go to Picture โ Overscan and adjust the values.
Also check if your cable supports the bandwidth you need:
| Permission | Required version of HDMI | Max, lossless cable length |
|---|---|---|
| 1080p@60Hz | HDMI 1.4 | 10m |
| 4K@30Hz | HDMI 1.4 | 5m |
| 4K@60Hz | HDMI 2.0 | 3m |
| 8K@60Hz | HDMI 2.1 | 1m |
If the band disappeared after the cable was replaced, the problem was that Xiaomi TV with support for 4K@120Hz (for example, Mi TV Q2) is recommended to use cables with Ultra High Speed HDMI certification.

Cheap. HDMI-Cables often cause artifacts. Invest in certified cables is cheaper than repairing a TV!
Method 6: Resetting TV settings to factory
If none of these things work, the last thing you can do is reset the TV completely, and it'll bring the TV back out of the box, eliminating any possible programming conflicts.
- Go to Settings โ Device โ Reset and Recovery (or Settings โ Support โ Reset on new models).
- Select Factory Data Reset (Factory Data Reset).
- Confirm the action by entering PIN-code (default 0000 or 1234).
- Wait for the reboot (it will take 2-5 minutes).
After discharge:
- ๐ง Reset the TV as if it were after purchase.
- ๐ฅ Update the firmware to the latest version.
- ๐ผ๏ธ Select Just Scan zoom mode or 16:9.
- ๐ Connect external devices and check if the band has disappeared.
