Query: Fine while it works

This monitor always produced a good quality image (the "UltraBrite" is worthless unless playing a game) but only lasted a few months. Note that the warranty on this series of monitors only lasts one year instead of ViewSonic's traditional three. Clearly there is a reason. ViewSonic used to produce excellent, reliable monitors, it is a shame.
