Why does the Xiaomi 15 Ultra screen have color cast at low brightness when the temperature is high or low?
Thank you for your support of Xiaomi products. The phones will undergo strict professional inspection before leaving the factory, so you can use them with confidence. The Xiaomi 15 Ultra uses advanced LTPO (Low-Temperature Polycrystalline Oxide) technology, which allows for adaptive refresh rates depending on the brightness and usage scenarios. This helps to improve power efficiency and ensure a smoother visual experience by adjusting the refresh rate dynamically to match the content being displayed.
In order to minimize flicker at lower brightness levels, the device also utilizes 1920Hz PWM (Pulse Width Modulation) high-frequency dimming technology. This high-frequency dimming reduces visible flicker at lower brightness, providing a more stable viewing experience. However, due to these dynamic adjustments and the interplay between brightness levels and refresh rates, you can notice slight color shifts in certain lighting conditions or at lower brightness levels, particularly when the temperature is high or low.
These minor color changes are normal and inherent to the screen's technology. They do not indicate any malfunction. Please feel free to use it.
