Query: Viewsonic P225 Professional monitor disappoints

While I was impressed with the speed (and price) in which this heavy monitor was delivered from Amazon.com, I am disappointed in its performance.The monitor had an evident color cast across the screen. No adjusments could compensate for the color cast. Tried relocation of the monitor, using another computer, the defect was consistent in any environment.Viewsonic replaced the monitor ( I was without for over a week as the transfer took place!) and the replacement monitor, while better, displays the same problem. I would not recommend this monitor to anyone looking for a monitor suitable for production photo work.
