Question ID: 731083
My company currently tests used monitors for resale. We currently use
a pattern generator and entry level technicians to evaluate the screen
quality. We are getting too many returns from our customers so I would
like to upgrade the system to performing more objective technical
tests using trained labor. What test equipment should I use? I have
looked at convergence testers, color analyzers, light meters, etc. but
I want to make sure that if the monitor passes the battery of tests,
we can be comfortable that the picture quality is as close to new as
possible.
