In the old days there were plenty of CRTs which could manage 100Hz refresh. I tried to drive mine at that refresh rate whenever possible, being sensitive to flicker.

refresh works significantly different on LCD screens vs CRT screens.
on CRT screens the image is drawn at one point and fades over time, refresh rate is how many times a second this point goes over the screen. there is always some flicker and high refresh rates minimize this
on LCD screens the image is stable, not 'draw and fade', different levels of brightness are achieved by flickering the pixels at different rates, but each pixel is run at that rate continually. Refresh becomes just the rate at which the image can be changed.
