The iPhone 17 Pro<\/a> models include an Accessibility setting to disable pulse width modulation (PWM), according to information found in the iOS 26<\/a> release candidate.<\/p>\n

\"iPhone
There will be a toggle located in the Display and Text Size section of the Accessibility settings on the \u200ciPhone 17 Pro\u200c. Users will be able to turn PWM on, or turn it off. A description:<\/p>\n

Disables pulse width modulation to provide a different way to dim the OLED display, which can create a smoother display output at low brightness levels. Disabling PWM may affect low brightness display performance under certain conditions.<\/p>\n

It is possible that the PWM toggle will be available on all iPhone 17<\/a> models, but we can only confirm that it’s an option on the \u200ciPhone 17 Pro\u200c.<\/p>\n

Pulse width modulation is used for adjusting the brightness of a display. PWM is designed to quickly switch LED or OLED pixels on or off to control the brightness that people perceive. Some users are bothered by PWM<\/a> and can see a flickering at lower brightness levels.<\/p>\n

Affected users often complain of eye strain, headaches, and other symptoms, but it is a technology that display makers use because it is energy efficient. The \u200ciPhone 17 Pro\u200c and perhaps other \u200ciPhone 17\u200c models could provide those who are bothered by PWM with a fix.<\/p>\n
