I have already purchased two monitors and have been disappointed. Every monitor I get seems to have a noticeable clouding around the corners, which is apparently common for led back light displays? Either way, is there a way to remedy the clouding or mura effect of a monitor, or is there a type of monitor that does not have this kind of effect? I have had an ah-ips and an Amva panel and both have the same clouding. I heard loosening the panel screws and laying it in its back for a while can alleviate some of the pressure and reduce clouding. If you know how to remedy mura or if you know what kind of display does not have the clouding effect, please let me know. Thanks!
