Unless you have a rubbish backlight, I don't see how an LCD panel can flicker? (actually I can see why, turn of dynamic contrast, and crank the brightness up, turn off energy saving. That'll stop the PWN on the backlight)
The refresh rate of a panel is not what it can display, the only real practical effect is on screen tearing. (I worked for a VFX company, trust me I've tested it.)
Even really fast displays take 5 ms to get from grey-white-grey.
I'm talking about the PWM, and if you need to use PWM at 100% , for some it would be much too bright.There are some options to correct it(contrast, or apps like flux), but they usually really hurt color reproduction.And sometimes even them don't lower brightness enough.
