Samsung or Viewsonic 22" monitor

[TinCow]

Here's more from Samsung:

Since a 15 inch LCD display contains 2,359,296 pixels, a19 inch LCD display contains 3,932,160 pixels, and a 24 inch LCD display contains 6,912,000 pixels, having a few "bad" pixels is not considered a defect. It is rare for a monitor to ship with or develop bad pixels. If or when a bad pixel occurs, it is not an indication that more will occur. It is usually a solitary incident.

By these stats, I would estimate that a 22" has about 6 million pixels, which by the class 2 standard is still 12 dead pixels before return.
