Which phone is better for "shim" ( pvm )?

Question

Screen resolution

Hello, I’m choosing between samsung (no matter what model) versus poco x3 NFC, and so: most Samsungs have PWM of 200 or more Hertz, but poco x3 has PWM at 2358 Hz, Poco X3 review Which one is less harmful for eyes ? I searched on google, but no one can give a definite answer to this question! Some say that it is better when the PWM is less, others, on the contrary, say that it is better when it is more in frequency ..... Already confused, help, is there someone here who can give an explanation? And which one is better When more or less?
