HP LP2480zx

After testing the HP w2408h, which left something to be desired, here we have the LP2480zx, part of the manufacturer’s pro range. According to HP, this screen has an extensive colour range and a rich visual quality and homogeneity. At first glance, this monoitor has a rather crude look about it. Beyond its appearance however is a real pearl in terms of ergonomics: vertically adjustable base, pivot, mounted on a platter, a 4-port USB hub and all the connection sockets you could wish for, not to forget the IPS panel which guarantees open angles of vision and colour homogeneity. Difficult not to give it maximum points.

Colour homogeneity does not automatically signify colour fidelity and and the default settings on the LP2480z do not give sufficiently good results for a monitor that aims at the professional image market. The colour temperature measure confirms what you can see with the eye, namely a dominance of blues which gives a dE of 3.9. Happily, by using the AdobeRGB mode and putting the temperature at 6000K you can reduce this twice over. The screen then settles at a dE of 1.8 and a contrast ratio of around 830: 1. Another plus point is that the panel is almost as homogenous as the colours themselves, with the average difference in luminosity between the different parts of the panel under 8 % as compared with 30 % for a standard monitor.

Reactivity is on a par with a good 2 ms TN which, coupled with a low luminosity in the dark, gives slightly better results than the average for films. However, unless you add a graphic correction chip, you’re far from television quality results. Gamers will also be disappointed to hear that the input lag is around two frames.
