Hmmmm.... Comments:
My monitors go on around 8:30 AM, and off about midnight;
I use them for about 2-3+ years before switching; I'm careful
never to pinch/kink the signal cord (a common failure
cause); do yours experience vibration or shock?;
is the voltage supplied to the monitors stable and
normal?; I've never had one fail in many years with three
in use simultaneously much of the time; perhaps a better
grade of monitor?; I dislike the color of LCD panels;
I would expect the illumination level of LCD panels to
go down with time, but compensation with the brightness
control is probably practical; LCDs use less current,
produce less heat, and have no linear distortion...
