What to do if the brightness at the top and bottom of the Xiaomi TV dims every time switching channels?
If the brightness at the top and bottom of the Xiaomi TV dims every time switching channels, please refer to the following information:
1. When switching channels on a Xiaomi TV, the brightness at the top and bottom can temporarily appear dimmer because the TV briefly displays the channel information overlay. Once the channel information disappears, the brightness returns to normal. This is expected behavior and does not indicate any issue with the TV.
2. If the dimming seems unusual or persists for an extended time, restart the TV to ensure all settings are properly applied.
3. Update the TV’s firmware to the latest version for any fixes or improvements.
4. If the issue continues or becomes severe despite these steps, it is recommended to contact Xiaomi after-sales service for further assistance.
