Summary: I bought mine May 2, 2010. It is now April 12, 2012. Less than 2 years. the display has continuously gotten dimmer. Green shading occurs at contrast points/lines/areas and is especially noticeable on lighter color tones (like skin or sand in a movie, picture and even in games. When I received the monitor, it had dead pixels and Viewsonic refused to do anything about it.
