Introduction

The dominance of the Eizo S2231W seems to be disintegrating. Although the Eizo monitor was out on its own with its S-PVA panel in he 22-inch class at the start of the year, there are now some other rivals, if only a few.

With the CG222W the Eizo S2231W faces competition from its manufacturer. The professional monitor from the CG (Color Graphic) series was designed for professional graphics workers and is in a completely different league with its price of more than a thousand Euro. The Lenovo L220x is also in a different scope and is also equipped with an S-PVA panel and is in the same price range, but has a considerably higher resolution of 1.920 x 1.200 pixels.

Thus, the new HP LP2275W has to measure up against just one rival – the Eizo S2231W. Even though this is an individual test, we have included comparisons between the two monitors from time to time.

In terms of features, there are small but fine differences: whilst the Eizo S2231W is equipped with a brightness sensor, headphone connection, additional D-Sub input and 10-Bit LUT, the HP LP2275W has a second digital input in the form of a DisplayPort connection. In addition, the 22-inch HP model is 125,00 Euro cheaper.

22 inch monitor living it large: HP LP2275w

In our test, we intend to clarify whether the HP LP2275w can keep up with the current best in class, the Eizo S2231W despite its considerably lower price or whether it is conquered by the more expensive model.

All results published in this test were obtained via the digital input of an XFX GeForce 8800GTX. Only the analogue image quality was measured via the analogue input. The measurements were carried out using the iColor Display software from Quato and the DTP94 und i1 Pro colorimeters.
