Re: Flat screen recommendation (PC) for high res graph?

["Gene Kim-Eng" <techwr -at- genek -dot- com>]

This is really not the case with LCD screens.  Unlike CRTs, whose
image quality can vary significantly with adjustments made during the
manufacturing process, LCDs have much simpler pass/fail critieria,
most commonly, the number of "dead" pixels resulting from faults
in substrate processing or module assembly - almost all of which
are totally automated - and the failures usually go straight to the
recycling bin. There is seldom a "second tier" of lower-priced 
products consisting of those that didn't quite meet the criteria for 
first quality.  .  The variation in display quality between different
products coming off the same manufacturer's line is almost entirely
the result of deliberate decisions made at the design level about
the number, density and matrix patterns of the switches laid out
on the substrate, all of which significantly affect the cost of the
display component.  Differences in quality control at all levels
for thiese products usually manifest themselves in the reputation 
of the manufacturer's products for having long working lives or 
exploding a month after the warranty expires.
