Why does Xiaomi have a Standby notch?

The standby cutout is not a breakdown, but a feature of the backlight and image processing, and on Xiaomi devices, this problem is due to several factors:

🔹 Energy saving mode: In Standby, the TV reduces the brightness of the backlight unevenly, which causes some areas of the screen to become darker.
🔹 Firmware errors: In versions MIUI TV below 3.0.12 was a bug that caused the matrix to malfunction in standby mode.
🔹 Hardware restrictions: Cheap models (e.g. Mi) TV 4A) use simplified lighting controllers that unevenly distribute voltage.
🔹 External devices: Connected through HDMI consoles (such as the Mi Box S) can interfere with the TV, causing artifacts.

Interestingly, on some models (such as the Xiaomi TV Q2 75), the cutout only appears when certain HDR or Dolby Vision settings are set, which is because the TV tries to save the color profile settings while on standby, but does so with errors.

Before you get to the solution, check if the cutout is connected to an external signal source. HDMI-If the cutout is gone, it's the console or the receiver, not the TV.

⚠️ Note: On some models (e.g. Mi) TV 4S) power saving shutdown can increase the power consumption in standby mode from 0.5 W to 2-3 W. If it is critical, try other ways.

Method 2: Update the TV firmware

In versions of MIUI TV older than 2.5.4, a bug with uneven backlighting in Standby was fixed. If your TV hasn't been updated in a long time, this could be the main reason for the cutout. Updating the firmware is free and takes no more than 15 minutes.

How to update:

Connect your TV to the internet via Wi-Fi or Ethernet cable.
Go to Settings → About TV → System Update.
Click Check Updates and wait for the search.

💾 Copy the file. update.zip flash drive (format) FAT32).
🔌 Connect the flash drive to the TV and select Update with USB refresher.

What to do if the update is suspended?

If the update process has stopped at 0% or 100% for more than 20 minutes: 1. Do not force the TV to turn off - wait another 10 minutes. 2. If there is no change, turn off the power for 30 seconds, then repeat the update. 3. If the problem repeats - try another flash drive (preferably no more than 32 GB, FAT32 format).

⚠️ Warning: After the update, reset the system cache: press the Menu buttons + Volume Down on the remote for 5 seconds at the same time, which will help to avoid conflicts between the old and new settings.

If standard settings don’t work, you can try hidden options available through the service menu, a method that requires caution, as incorrect changes can degrade image quality.

Instructions for entering the service menu:

Turn off the TV and wait for the full transition to Standby mode (the indicator should flash red).
On the remote, simultaneously press the buttons: Menu → Input → Volume Up → Power Hold them for 10-15 seconds until the service menu appears.

Parameters that need to be changed:

Parameter	Recommended value	Note
Local Dimming	Off	Disables zone lighting that can cause a cutout
Backlight Uniformity	High	Aligns the brightness of the lights throughout the screen
Standby Brightness	5–10%	Reduces brightness in standby mode, reducing the visibility of the cutout
Panel Refresh Rate	60 Hz	Remove artifacts at low refresh rate

⚠️ Note: Do not change Panel Voltage or Gamma Correction settings, this can cause permanent damage to the matrix. After the changes, be sure to reset the image settings through the standard menu.

💡

If the image is dim after the service menu changes, return the Backlight Uniformity setting to Medium and increase Standby Brightness to 15%.

Method 4: Hardware solutions (for advanced users)

If the software methods didn't work, the problem could be the hardware.

🔌 Faulty power supply: Unstable voltage leads to uneven backlighting.
💡 Degradation LED-Over time, LEDs lose brightness and some areas become darker.

For Mi Box S models and other consoles connected to the TV, try:

Disconnect the console from power for 1 minute, then connect again.
Update the console firmware through Settings → About the device → Update the system.
Reset the settings HDMI-port on the TV (Settings) → HDMI → Port discharge).

Prevention: How to avoid the appearance of a cutout in the future

To prevent the problem from returning after elimination, follow these recommendations:

🔋 Do not use cheap power supplies – they can give unstable voltage.
🌡️ Avoid overheating: Install the TV in a ventilated place, do not close the vents.

For models with OLED-Matrix (e.g. Xiaomi) TV Master) the cutout may be due to the burning of pixels, in which case it will help:

Launch Pixel Refresh in the service menu (1 time per month).
Use dynamic screensavers instead of static ones.
