Summary: I purchased the HP2011X because of it's very good rating. I tried it and found out immediately that when you tilt your head up or down, the screen becomes foggy (dark) and unreadable at the edges of the monitor. I was disappointed and returned it. With this experience, I started looking for another monitor and paid attention to the field of vision. I purchased the HP2311X. What a difference. The 2311X in my opinion has a much better field of vision.
