Aah didn't know that.
As far as I understand AMVA monitors are supposed to be in between the Ultrasharp series and lower end dell models. They do have some higher end feature and are still lower in cost.
For your requirements it makes more sense as it will save you some money. But I doubt it beats an ips panel in image reproduction. Why not take a demo for both and decide yourself, you can't go wrong with either of them.
