Nothing Phone (3) originally had a 2,160Hz PWM rate, but a recent software update changed it to 960Hz when the display operates at lower brightness levels. Despite still supporting 2,160Hz, the company prioritized picture quality for the final retail software.
For most users, PWM technology is harmless, but some may experience symptoms like eye strain, headaches, nausea, and vertigo, especially those sensitive to lower flicker rates. Other brands are also enhancing PWM rates on their devices, like the Honor Magic 6 Pro, supporting a 4,320Hz PWM dimming rate below 30% brightness.
