The HP z27x is loaded with features. Beyond the usual features like a USB hub and multiple inputs it offers multiple color space support for AdobeRGB, DCI, and even Rec. 2020. It goes well beyond this by offering the ability to self-calibrate any of the presets to your own requirements and an Ethernet jack for network management.

With all of these features it is obvious that the HP z27x isn’t a monitor generally meant for home use. It is very much targeted at the professional world, say someone like Pixar, where control and flexibility are necessary. The first feature that the HP z27x brings to the table is support for a very large color gamut.

While AdobeRGB support is common in professional displays, a gamut that goes beyond that is not as common. The HP z27x also has support for the DCI P3 (Digital Cinema Initiative) and Rec. 2020 which is the color gamut of the UltraHD TV standard. Now nothing can actually display the full Rec. 2020 gamut, and that includes the HP z27x, but it gets much closer than other monitors out there on the market today. We will see later just how large the gamut is on the HP z27x.

It also has features for working with digital cinema material. It is still a QHD display with 2560x1440 resolution but can display true 4K content (4096 pixels wide) through either scaling or 1:1 pixel mapping. Using this mode lets you scroll around a larger desktop or scale it to fit onto the screen so you can see your whole desktop and then zoom into 1:1 mode when you need to edit. Very few displays can handle a 4096 pixel signal but the HP z27x can.

Your inputs are limited to a single HDMI 1.4a and dual DisplayPort 1.2 inputs. Either of these can accept a 4096 pixel signal, though at 24Hz and not 60Hz due to bandwidth limits. There is a complement of USB ports with four USB 3.0 ports and two USB 2.0 ports. Four of these are on the bottom of the display and are harder to access but two are on the side and convenient for flash drives and other accessories.

All the features of the HP z27x are accessible through a well designed on screen display. Straight out of the Dell handbook for how to do it right, buttons on the right control the features while they are clearly labeled on-screen. There are no annoying touch sensitive buttons that are hard to use or controls that don’t work intuitively. Finding the setting you need is easy, as is switching between calibrated presets. HP seems to have actually spent time working on the OSD of the z27x to make sure it is easy to use, which I can’t say for most companies.

The Ethernet jack on the HP z27x is a first for a display that I have reviewed. After all, why does a monitor need Ethernet? What it allows is for complete management of the display over the network and to tie it into your account management. Once again, let’s look at a company like Pixar. You have people that work on film production and home video production. Each of these has a different color gamut and a different setting in the HP z27x. With the management features in the HP z27x you can tie accounts to those profiles. Log in to a machine and the display automatically chooses the appropriate profile for you. If it is a work environment where people share machines during different shifts, this prevents errors from happening. You can get notifications on how long it has been since a calibration happened, letting you know that a monitor calibration needs to be done and sending someone to do it. It’s another feature that the home user will not need, but it can prove very useful in a large corporate environment.

    @Chris: when seeing this article in rss, it's not clear that this is a monitor review (the word 'display' comes up nearly last).
  • chowyuncat - Wednesday, December 3, 2014 - link

    Could you put Apple's 27" Cinema or Thunderbolt display's input lag in your monitor reviews?
  • cheinonen - Sunday, December 7, 2014 - link

    I don't have one so I can't do that, and they don't have HDMI ports so I can't measure it the same way either.

    Am I the only one who thinks this article lacks an introduction?

    Good review otherwise although I agree with kyuu regarding the uniformity issue, unless the monitor was purchased by AT I don't see how requesting another sample would've made a difference. And even then you can publish both sets of numbers and let the readers draw their own conclusions. As it is we have no clue whether the results are due to a damaged sample or simply poor performance.

    Who needs QHD? Who needs 27"? Are gamut pros happy that they dont have yet 4K minimum 30"- 40" monitors?

    Chris, thank you for what I thought was a very good review. My question is not just to you, but to the community that has participated in this forum as well. Is there any new consensus on the uniformity issue that Chris raised? It does seem an achilles heel, if the issue is not specific to the z27x unit that Chris evaluated. Since last comments posted, has anyone purchased (or know anyone that has purchased) a z27x to confirm or disclaim what Chris communicated as a serious issue for the model? There aren't many options that cover the full range of color gamma options at this price point, so I am inclined to buy one, but felt I should first check into the community. As an alternative, I am considering the z24x, but perhaps uniformity is an issue with this model as well. Thanks in advance for the any additional feedback from the community here.

    Anybody have an accurate weight for this WITHOUT the base?
