Introduction

In terms of appearance, the HP ZR22w resembles its bigger brother, the popular HP ZR24w, to such an extent that the two could easily be confused. The same technology has been used for the connectors and some other features. As well as the difference in size, however, there are also other distinguishing features. The HP ZR22w is equipped with an S-IPS panel with a resolution of 1.920 x 1.080 pixels, but also offers 16:9 format. The power consumption should also be considerably lower with a typical 28 watts. All other differences that are not immediately obvious will be examined in the course of our review.

The results published in the test were obtained via the digital DVI output of an Asus AMD Radeon HD 6970. The iColor software and the Colorimetre HCFR software were used in conjunction with a spectral photometer (EyeOne Pro) for the colorimetric measurements. The minimum black value was measured using the Colorimeter DTP94. The external playback of video material was carried out using the Sony BDP-S350 Blu-Ray player, which was connected using a DVI cable and a DVI-HDMI adapter.

Scope of supply

The accessories and the base were positioned in the top section of the box and the monitor itself was located in the lower part between two thick pieces of Styrofoam and was therefore well protected.

On the left, the open box with the accessories and on the right, the monitor in its packing.

The scope of supply includes a VGA cable for the analogue connection, a DVI-D and DisplayPort cable for the digital connection, a USB cable, an external device cable, a getting started guide and a CD. The CD contains a detailed manual and the driver for the monitor.
