Query: Apparent quality control problem

Acer monitor I ordered arrived Dead on Arrival, with a bright-white dead pixel so visible right in the center of the monitor. How could a quality inspector have missed such an obvious defect? I'm returning it. This monitor also looks and feels cheap, compared to much more sophisticated design of Samsung monitors, which are only slightly more expensive. I'm going to stay away from Acer from now on.
