Query: Unacceptable Failure Rate

We have about 200 of these monitors and the failure rate is about 50-60%. It's often difficult to gauge the reliability if you order only one or two because bad monitors are probably chalked up as a fluke and quickly replaced by the company. I can definitely attest that these monitors are ticking time bombs just waiting to fail (probably right after the warranty expires!) They have caused me headaches to no end because they don't fail right away; rather, they take extended periods of time before they realize that a signal is being sent to them and remain powered off or in a sleep mode. Eventually, they will no longer come on at all. ViewSonic has definitely dropped the ball on this one and should be ashamed for allowing such a shoddy product to go out to their customers. Please learn from my experience and stay far away from this one.
