LCD reliability at the pixel level is vastly greater today than it was
even several years ago. A new, flawless display is the rule.
Nevertheless, at the end of a few months use, I will venture that many,
if not most, LCD displays have at least one dead or hot pixel. On
higher resolution displays, 1280x1024 or greater, the pixels are small
enough that a dead or hot pixel can be hard to see unless the user does
specific tests like solid primary colors, white, or black backgrounds.
After a couple of months of use, most users tend not to notice the
details that a new owner might. One or two bad pixels are almost
inconsequential in a population of one million or more. Screen dust and
dirt are far more annoying problems. Video card/chip failure is
probably the most probable display failure mode if newsgroup postings
are any indicator. IMO.
