It’s been about 18 months since we saw some interesting new models from HP. They have of course been producing monitors and computers for many years, but it was back in September 2008 when they sparked our interest with the launch of their HP LP2475W monitor. This was an interesting model featuring an IPS panel and some pretty high end specs which at the time were quite unique in the 24" sector. There were hardly any IPS panels at this size available and the LP2475W became the first of a new wave of screens offering this technology to the masses. Around the same time HP released a 22" equivalent, again breaking from the market norm of TN Film panels, and offering a model based on S-PVA technology. Their LP2275W also became a bit of a trend setter and other manufacturers soon followed with IPS, MVA and PVA offerings in this kind of size range. In April 2010 they released their ZR range of monitors as well, including a new 24" offering and a new 21.5" model. The ZR24W was another IPS addition to the 24" market and was a very popular choice since it was again breaking market trends. It was not following the pattern of high gamut colour spaces which was becoming popular with manufacturers at the time, instead being a rare standard gamut IPS offering in the 24" space.
Now HP have released a collection of 4 new models in their ZR range of screens, again bound to attract a lot of attention. There are models available in sizes of 20, 21.5, 24 and 27 inches. We have already reviewed in detail the 21.5" ZR2240w and 27" ZR2740w, and now we have with us the 24" model for a full test. This 24" model is called the ZR2440w. HP have stuck with IPS panel technology throughout the range and also now combined this with the currently popular W-LED backlighting.
