Hello all,

I am struggling to figure out if it’s using anything more than a 60hz screen or lighting/natural light as I get sick for days after using a Dell G5 laptop at 120hz but I don’t get sick with my HP laptop that maxes out at 60hz. (Sick = nausea, lightheaded, weird head feelings, leg weakness, numbness in the heel of the foot).

I thought it was the hz, but even our home computer (60hz max) hooked to a TV causes the same issue, but that is in a hideaway so brightness around the screen is not very bright.

My work laptop is connected to an external monitor that also maxes at 60hz.

Does anyone else get nausea, weak legs, weird head feelings on higher than 60hz screens or when the brightness of the environment around the computer screen is not just right?

Thank you,

K.

    Dizzy Maybe you are been affected by the flickering of the led backlight used in some displays or PWM, oled, qd oled, don't have a backlight but they flicker too, and this may cause dizzines, nausea, tinitus, weird head and neck feelings, etc, it could be also related to vestibular problems or binocular vision dysfunction problems.

        Abeabe thank you. I was checked for BVD and all is good. There is a B12 deficiency and some eye convergence issues. I turned the brightness all the way up to reduce PWM. It just seems odd that I am fine on one computer but not the other.
