ViewSonic is committed to customer satisfaction by providing the highest quality products in the industry. The result is that our LCD displays generally have very few non-performing pixels. For example, an 15" XGA (1024 x 768) display has nearly 2.35 million sub-pixels. A product exhibiting 4 non-performing pixels would equate to an extremely small 0.00016 percent of the total sub-pixels.
(1024 Horizontal Pixels) * (768 Vertical Pixels) * (3 sub-pixels per pixel) = 2,359,296 sub-pixels
[(4 non-performing pixels) / (2,359,296 sub-pixels)] * 100% = 0.00016%
To ensure the highest performing displays, ViewSonic sets limits as to the allowable number of pixel anomalies. This policy applies to all ViewSonic LCD displays during the DOA protection period within Hongkong
