Why does the white screen of the POCO F7 Ultra have vertical stripes at low brightness?
Each phone undergoes strict professional inspections before leaving the factory, please feel free to use it. The OLED screen uses DC dimming at high brightness and PWM dimming at low brightness. There are stripes in scenes with low brightness in the DC range. This is an inherent characteristic of the OLED screen and is a normal phenomenon.
You can try to adjust the following settings to see if you can get a better experience: [Settings] >> [Display & brightness] >> [Color scheme] >> [Vivid (recommended)]. By adjusting the position of the point in the interface ball, change the preference of the screen display effect.
