The ViewSonic ColorPro VP2776 is a highly capable 1440p professional monitor with two notable extras: a 165Hz refresh rate (making it good for video editing or game design) and a color calibrator.
Several people mentioned the 27-inch Viewsonic VP2785-4K in the comments to the previous post. I almost listed that one as being a good alternative, but B&H Photo lists it as "No Longer Available" and the manufacturer currently lists it as.
