The issue with CRT's and refresh rate isn't so much to do with the actual refresh rate itself (says the epileptic); it's the phosphor decay rate. Any CRT phospor compound has is not instant on/off; it gets brighter under excitation along a curve, and darkens along a curve. TV phosphors have a relatively long decay rate; that is what keeps strobing and frame jerking from being a problem, as well as the comparatively low refresh rates. THings also change so slowly in video, that the long decay rate effectively becomes a poor form of cheap motionblur. Computer monitors have phosphors with much higher decay rates, as the displayed data can change totally in the space of a single refresh cycle. The low rate phosphors would make a CRT next to unreadable. The downside is that anyone who is sensitive to strobing due to epilepsy, eye focus or strength issues, or luminance intensities, need to tweak and fiddle with their CRT until they hit the magic number that doesn't get them. And LCD's are not safe, particularly for those with siezure conditions. Remember that they are backlit, almost exclusively by mercury vapor flourescent bulbs. As they age, they will develop flicker....and it will have nothing to do with refresh rates, as the light source behind the montior image is what will be flickering, most likely at 50-60hz, from the power line. And that just happens to be one of the 'sweet' spots for eyestrain and seizure triggering alike. And I can confirm that living with flourescents in the workplace is a PITA, Xeno. And you can't get away from them; just keep a map in your head of where every failing bulb is and try and stay out of its influence......
