5 wqhd-monitors with AdobeRGB: professional monitors

Additional price wider colour space can be justifiable

HP DreamColor Z27X

We already covered the HP DreamColor Z27X in Hardware.Info TV, but because the model is still available and because we had the possibility to receive it in our lab, we tested it using our new test method. With a price at about 924 pounds / 1000 euros this monitor is not cheap, so we have high expectations.

The Z27X rests on a height adjustable base, on which the panel can rotate, pivot and tilt. Like Dell, HP leaves out VGA- and DVI-connectors but uses two full-size displayport-inputs, whereas Dell offers a mini- and  a standard one. A usb 3.0 hub with four downstream connectors is also present.

After the Eizo monitor the Z27X consumes the most power: 42 watt at 150 cd/m² and just shy of 60 watt at maximum brightness. The maximum brightness is slightly higher compared with Eizo at 283 cd/m², while the black value is slightly lower which directly impacts the contrast: 866:1 in the checkerboard-measurement is clearly higher and not far behind Benq and Dell. In terms of uniformity the Z27X ends up in the middle, which is also the case for the horizontal viewing angles. Vertically it is slightly better than the Benq, which ends up in second place here.

The colour quality in standard mode does not make us very enthusiastic, specifically the colour temperature that is way too high is a painful point. The average colour fault of 3.68 does not impress us either. In sRGB-mode the result is slightly better, but not a lot. Unfortunately the colour temperature in AdobeRGB-mode is still 7747 K, while the coverage of the colour space is 98.6% - this results in first place. However, the average colour deviation is still 3.47, the average grayscale deviation 5.33. The gamma ends up at an average of 2.1.

The colour balance of the HP Z27x is not optimal.

Unfortunately we were unable to calibrate the Z27x for this article, because our spectrometer suddenly stopped working. We will have to test this at a later date, but out-of-the-box this result is certainly not what we would like to see.
