High resolution displays are becoming the industry norm and HP added a few new ones to give buyers more options. They introduced two additional 4K models and its first 5K model. They also introduced an extra wide curved display though it doesn’t quite reach 4K resolution. The two new 4K models are identical except for the size. The Z24s and Z27s are 23.8 inch and 27 inch displays with a 16:9 ratio and a 4K resolution. Each model includes four USB 3.0 ports and a mixture of HDMI and other inputs. The 5K display definition is fairly tame but gives a 218ppi pixel density. The Envy 34c is a 34 inch display with 3440×1440 resolution and a 21:9 aspect ratio.
