Why do vertical bars appear on the Xiaomi 15T Pro's screen at low brightness?

Thank you for your support of Xiaomi. When the Xiaomi 15T Pro screen is set to low brightness, vertical bars or areas of slightly uneven shading appear, sometimes referred to as the Mura effect. This occurs due to DC dimming, a feature used to reduce flicker and improve visual comfort at low brightness levels.
This effect is a normal characteristic of OLED screens and does not impact overall display performance, usability, or long-term panel quality. Each device undergoes strict quality control to ensure screen uniformity and reliability. Variations in pixel brightness are typical at low luminance levels and are more noticeable under certain lighting conditions.
To ensure an optimal experience, please refer to the following information:
  1. Go to [Settings] >> [Display & brightness] >> [Color scheme].
  2. Select [Vivid] and adjust the dot position in the [Color temperature] ball to fine-tune the screen display according to your preferences.
These adjustments help maintain color accuracy, reduce perceptible variations, and improve overall viewing comfort.
