Why does the POCO X7 Pro not support global DC dimming and Anti-flicker mode?

Thank you for your support of Xiaomi products. The POCO X7 Pro supports DC dimming for high brightness and PWM dimming for low brightness. The phone employs a 1920Hz PWM to adjust brightness, which is effective for reducing flicker at low brightness levels. Xiaomi products are strictly inspected before leaving the factory to ensure that the products meet Xiaomi's specifications. You can use them with confidence.
At the same time, you can try the following methods to turn on the eye protection mode: [Settings] >> [Display & brightness] >> [Reading mode], and change the screen effect preference.
