Their resolution is pure. Too often a CRT will not be delivering the high
resolutions gamers are thinknig they are getting, because of the shadow mask
on most CRT's. The number of scanlines isn't really the same as the
resolution (dot pitch).
Indeed, I've seen many a CRT advertised as supporting 1600x1200 resolution,
and indeed it will take such a signal from a video card and display the
image, but when you take the physical size of the CRT, the dot or stripe
pitch, and work out the number of physical light elements available to
display the image, you'll discover that you don't really have 1600 sets of
color stripes or dot triples horizontally across the tube, until you get
up to about the 21-inch size range.
LCDs do not suffer from pincushion, barrel, or trapezoid distortion.
They do not suffer from image size pumping as some cheap CRTs with
not-very-stiff high voltage power supplies can as the amount of white
in the image changes significantly.
I have an older CRT monitor whose image would start to oscillate slightly
every time the outdoor security lights came on around sunset. I actually
had someone from Facilities come to measure the magnetic field being put
out by the security light outside my office window, and he claimed it was
less than that put out by a pencil sharpener. And that was a fairly high
end Mitsubishi monitor that was so sensitive to magnetic fields.
LCDs do have their drawbacks, but they have a lot going for them.
