I just leave this here for mention a budget one. By connecting up via displayport it is producing truly amazing 8bits color depth, and decent response time. I have been verified both of these claims already, as well as the panel itself which is assembled with - an LG product, seen it from panel distributor catalogues. Funnily enough Asus also have a product with the same panel but it is/was sold for double the price. So it is the better deal.
Just wondering how many of those displays from the 1K-2K price range will be satisfying the promises, and how much of the real advantages they provide (for the price) over the cheap ones such as this.
