If you’re getting dizzy using PROLED MacBook Pro, you are not alone

AI-summarised brief · reviewed before publication

Apple’s latest MacBook Pro models employ pulse‑width modulation (PWM) to control screen brightness, resulting in a 240 Hz flicker with a 56 % amplitude that some users report as eye strain, headaches, and vertigo. The strobing effect, while less overt than a flashing light, is continuous and covers a wide field of view, potentially triggering flicker vertigo, photosensitive epilepsy, or aggravating conditions such as migraines and traumatic‑brain‑injury‑related photosensitivity. Experts consulted by AppleInsider note that susceptibility varies with individual health, fatigue, and exposure duration. Apple’s earlier Mini‑LED MacBook uses a much higher PWM frequency (14,880 Hz), which mitigates these effects. The article advises users prone to photosensitivity to consider alternative displays or adjust usage habits to reduce discomfort.

💡 Why It Matters

  • · The PWM design reintroduces a health‑risk factor that many professionals rely on for long‑hour work, forcing a reassessment of display safety standards across premium laptops.
