Summary: This monitor was shipped with the box obviously opened by someone and one of the back screw heads stripped. I appears that it may have been worked on or the factory over-tighten the screw. I sent it back for a replacement. The replacement had a one inch scratch on the back. I keep it after Amazon.com gave me a 20% discount. Sad that Viewsonic's inspectors are not seeing these damages or are allowing the products to be packaged and shipped with damages.
