Make sure that the monitor has at least a 3 year warranty with it. This
should include the backlight. Most are rated at 20,000 hours. This means
that at 20,000 hours, the back light may be at 50% of its brightness from
new. Most TFT monitors are rated with an MTBF of 20,000 hours. CRT
monitors are rated to about 30,000 to 40,000 hours depending on the make
and
model. MTBF = Mean Time Between Failure.


Now if only they'd come up with a standard size and color temperature tube
for these, and make them user, or at least easily shop replaceable rather
than burrying them deep in the panel.
