I think our sight is all a little different. I can clearly see 50/60hz strobing in light when others can't. Back in the old CRT days I would get strained eye sight and nausea if I worked at monitors running below 85hz, unless it had long lasting phosphors like the old monochrome CRTs.
Good LCDs are static unless you're running a dvi-vga-displayport-vga-hdmi dongle monster where the pixels are inevitably shifting a bit every instant. What you're more likely to be seeing is PWM backlight flickering at you.
If it's indeed the LCD and not the backlight, pray tell us the model so we don't end up buying it.
