I recommend this article. Some modern LCDs employ techniques which
can add flicker, compared to older LCD monitors. They do this,
to change the apparent response time.

"We haven’t yet tested the FP241WZ in our labs, so I can only quote
a review published by the respectable BeHardware (“BenQ FP241WZ:
1st LCD with screening”). Vincent Alzieu writes there that the new
technology indeed improves the subjective perception of the monitor’s
response time, but although only one out of the 16 backlight lamps
is off at any given moment, a flickering of the screen can be noticed
in some cases, particularly on large solid-color fields."

Another possibility, is a mechanism like this. 6 bit panels and dithering.
