REVIEW: Dell E228WFP Part 8
The brightness is somewhat lower than the guide value towards each side, with the largest deviation on the left-hand side at the edge, where losses of up to 19% were noticed.
However, these figures seem more dramatic on paper than in practice. In normal lighting, the brightness deviations are hardly noticeable and thus, we rate the illumination of the E228WFP as satisfactory overall. E would also like to point out that the illumination of LCDs is generally subject to a certain amount of deviation.
The manufacturer states that the viewing angles of the E228WFP are 160 degrees horizontally and vertically. However, these official values belong to the realm of fantasy and are not achieved in real life – as is the case with official viewing angles given by most other manufacturers as well.
Side viewing angle from the right and frontal view.

In practice, the E228WFP already demonstrates colour and brightness changes at a side viewing angle of 140 degrees. When viewed at a downward sloping angle, the monitor demonstrates extreme colour changes. However, all in all, the viewing angles of the E228WFP are quite normal for a TN panel and can therefore be rated as satisfactory, especially as the E228WFP is almost identical to most of the 22" widescreens we have tested in terms of viewing angle stability.
The subjective colour reproduction quality of the E228WFP is astonishingly good. Despite its TN panel, only a slight striation is noticeable in fine colour gradients. A somewhat stronger stepping can be observed in linear grey gradient.
We calibrated the colours of the Dell E228WFP using the Gretag Mac Beth Colorimeter Eye One Display 2 and Quatographic’s iColor Kalibrierungssoftware. We then measured the reproducible colour space and the colour reproduction quality of the monitor.

The colour space we measured for the E228WFP covers the sRGB working colour space as far as possible. This means that the Dell is suitable for graphics use in the multimedia area where the colours are not as critical (e. g. Web design, Video cutting). However, this monitor is not adequate for use in professional graphics work.
