If I pick a guitar string in front of my 90 Hz CRT, I notice a
stroboscope effect. If I do the same in front of my 60 Hz LCD, there is
no stroboscope effect. So the issue seemingly isn't the 60 Hz, nor a
fixed frequency for the backlight. If I decrease the CRT's frequency to
60 Hz, I get another kind of flickering for the CRT, than
what I notice for the LCD.
