Everything depends on your individual eyes, what you use the monitor for, and the setting of the monitor use. For my desktop use, 30Hz is actually fine. It's what I've used for over six years. I have, within arm's reach, all I need to switch to 60Hz but it hasn't seemed worth the reconfiguration effort. Details of my use: - most of what I do is fairly static. I don't seriously watch videos on my desktop (YouTube seems fine). I don't play games. - my monitor is 39" and perhaps 24"-30" from my face. UltraHD. - I wear special fixed-focus glasses when using the monitor (as opposed to my regular progressive glasses Gamers want refresh rates well above 60Hz. To get that, they seem to be willing to choose lower resolutions. That would be a terrible trade-off for my use. Films are traditionally 25 frames/second (each frame is flashed twice by traditional projectors).
