Accurate color reproduction may not be a monitor's most important characteristic for gamers, but it's critical for professionals that create games, movies, and work on photography. HP designed its DreamColor Z24x G2 and DreamColor Z31x Studio displays with these folks in mind. The company's DreamColor product page proudly proclaims that the DreamColor line won a 2015 Scientific and Engineering Award from the Academy of Motion Picture Arts & Sciences.
At first glance, the DreamColor Z24x G2 is a nice, conventional 24" IPS panel with a 1920x1200 resolution that allows users to play a 1080p video and have a little extra room for software icons. Gamers won't be excited by Z24x G2's 6-ms response time and 60 Hz refresh rate, but photo and video professionals will enjoy the display's 10-bit output and color gamut spanning 99% of the Adobe RGB space. Brightness can go as far as 350 cd/m².
The Z24x has a DVI-D port, an HDMI jack, one DisplayPort input, and a DisplayPort output for daisy-chaining. The included stand has height, tilt, swivel, and a 90° pivot for easier transitions to portrait mode. An integrated four-port USB 3.0 hub should make getting photos in and out of the attached system more convenient.
The star of the show is the DreamColor Z31x Studio display. As one might guess from the name, the Z31x is a 31" inch monster with a resolution of 4096x2160. As is the norm for monitors with so many pixels, the maximum refresh rate is capped at 60 Hz. The response time is listed solely at 20 ms on-to-off, rather than the typical grey-to-grey response time. The Z31x has an HDMI 2.0 jack and a pair of in-and-out DisplayPorts. There's also a built-in four-port USB 3.0 hub and a pair of what HP calls "DreamColor USB 2.0" ports, meant for plugging calibration hardware and running monitor firmware updates.
For some users, the Z31x's most important feature might be its integrated colorimeter, which can be set up to run calibrations during off hours and can be matched to a company-wide reference instrument for color consistency across many machines. One last built-in goodie is a KVM switch that allows using the monitor with two different systems.
HP's DreamColor Z24x will be available in early July for $560. The DreamColor Z31x will be available "sometime this year" for a wallet-frightening $4000.
