this seemed like a great purchase at the time, and I'm sure this is a good monitor. I got the dud. Did not get around to setting it up until it was past the return window, my fault. but right out of the box within a few minutes I noticed localized dimming occurring on the screen. Thought it was some kind of ambient light detection system in the monitor. but upon further investigation, all I had to do was tap the monitor and the different parts of the screen would go dark. What a mess, I guess it's $200 down the drain. Update... much to my surprise amazon is sending a replacement monitor. This is outstanding customer service. The replacement monitor has been great.
