It’s really bad for me which is gutting as I love the machine it just literally makes me feel I’ll using it. Tbh I have never noticed any issues before so no idea why I’m so sensitive this time. I have an iPhone 13 pro which is meant to be really bad for it but no problems using that. Maybe it’s the frequency ?
Yes it is. These are 14.8 KHz, which is quite low. Typical MacBook screens are about 120KHz. Now while MiniLEDs perform differently to PWM compared to fluorescent backlights (i.e. the numbers don't directly compare), this difference is still noticeable. When these MacBooks were released people who used previous MacBook without any issues were experiencing these problems.
