Comment by WhitneyLand | original | The MacBook Pro's OLED PWM Problem: When a 'Better' Display Becomes Worse to Use
[−]WhitneyLand · 2026-11-15 Sun 18:05 UTC · link
Interesting it seems hard to find any research that concludes 240hz or higher frequency flicker causes physical discomfort. Is there a single paper that concludes this? Older studies were based on ~100hz fluorescent lighting.

In a rigorous blinded comparison, would the new OLED MacBook cause more physical discomfort than the mini-LED model? How to explain all the symptoms being experienced?

What’s most likely?

1. Real MacBook hardware issue

2. Nocebo. Expectation of PWM problems > real physical symptoms

3. False correlation. Real headaches/eyestrain but from other causes

How surprising would it be if the answer is not (1)?
