As already mentioned, the 15.6 inch LED display in 16:9 format is one of the more significant innovations of the current Studio 1555 series. Dell follows, like almost all other manufacturers, the latest trend of orientating themselves on standard movie formats. As already often explained, this is quite helpful at rendering BluRays and DVDs, as the black bar usually turns out significantly thinner and therefore the real image is larger than on the 16:10 screens, but you have the disadvantage of a lower image height available for the common PC applications. This means only the upper part of a website or an application is seen and this leads to an increased need of scrolling.
This critique point naturally only applies to the WXGA screen with a resolution of 1366x768 pixels. A sufficient overview for all applications should be provided for in the alternately available Full-HD version (1920x1080 pixels), in any case. We were positively surprised from the comparatively low-priced Full-HD surcharge option: For merely an additional 60.00 Euros you can enjoy native Full-HD images.
The lower resolutive screen was also found in our test sample. The screen (SEC5441) reached a display brightness a maximum brightness of a good 213 cd/m2 in the test. The LED screen can also score with an above average good illumination of 88.7%. A good average is the maximum reached contrast ratio of up to 180:1, too.

Possible hopes of an especially high-quality screen had to, at least in the standard WXGA display, be abandoned in regards to color representation. Our measurements with support from the Spyder 3 colorimeter from Datacolor show a color space which is considerably smaller than the common RGB color space, for example. In analysis of the color space diagrams, an outliner in the blue color area becomes obvious. Hence, the display is to generally be rowed into the league of the standard screens, in regards to color representation. In comparison, the extremely large color space of the Studio XPS 16 from Dell , equipped with the RGB LED display, becomes especially impressively obvious, but equipped with the RGB LED display.
However, due to the low surcharge of the alternate Studio 15 Full-HD version, you shouldn't await a large improvement in regards to color representation in this display. According to various unverified internet information, several displays from different manufactures are used in the Studio 1555, which partly differ considerably from each other.
It doesn't matter which display is chosen, there is no way around the TrueLife surface. TrueLife is Dell's name for a glossy display. The test for the display's outdoor suitability was, as expected, rather disappointing. The given brightness would still be adequate to provide a sufficient image contrast at least in the shade, but the reflections which turn up make working with the device very arduous.
The given viewing angle stability definitely doesn't belong to the display's strengths. Already the slightest deviation from the ideal, that is to say the perpendicular viewing angle, color changes and also an increase of reflections can be observed. This applies especially to the vertical viewing area, whilst along the horizontal axis you struggle more with reflections than with color changes.
