REVIEW: Dell 2209WA (s) Part 8


The brightness distribution of the Dell 2209WA is almost very good. At a measured starting value of 140 cd/m² in the middle of the screen, the maximum deviation in the lower left corner is less than 12 percent. Thus, the average deviation is just about 6,3 percent. This result is absolutely to be rated as very good and almost matches the constant brightness distribution of monitors with LED backlights.

In fact, the colour temperature drops a little, but this deviation is in no way visible as a colour gradient. However, it must be mentioned here that the backlight is subject to a certain degree of variation and the result is not identical for every model.

Viewing angle

The viewing angle details provided by the manufacturer are generally more of a wish than a fact, especially for TN models. An IPS panel is used on the Dell 2209WA. This technology allows for larger viewing angles and therefore, the manufacturer’s indication of 178 degrees horizontal and vertical is very accurate.

Technical details on the viewing angles are not worth much if the subjective impression does not agree with them. However, we noticed something unusual in our viewing angle test for the Dell 2209WA. When a bright, colourful image is displayed, even very large viewing angles hardly change the image at all. The colours simply lose something of their intensity. Things are different for an image with a lot of dark or even black elements. In such images, a bright, satin-matte shine can be seen at even slight changes in the viewing angle, as is the case for most IPS panels.

Measurements and calibration

Below, we tested the colour accuracy of the Dell 2209WA and checked how well the LCD monitor could be calibrated. The results are mainly of interest for graphics and photo editing. They are largely negligible for office use and games, since the subjective impression is more important in these applications.

We then measured the maximum colour space of the LCD and compared it with the ISO Coated printing colour space and the sRGB colour space.

We only use a comparison with AdobeRGB and ECI-RGB 2.0 for models which have an extended colour space. This is not the case for the Dell 2209WA.

Colour space comparison

sRGB is the lowest common denominator for the interaction between various input and output devices in the consumer sector. In addition, Windows assumes sRGB if no colour profile is present for a device or graphics file.

Many colour printers function using the sRGB profile on normal paper. This is also why the sRGB colour space is significant for "normal users" unlike the ISO Coated printing colour space.

The comparison with the ISO Coated colour space used in offset printing is interesting, since this generally represents the least that modern inkjet printers can manage. Many modern inkjet printers and printing processes also cover an even larger area.

3D colour space comparison

The 3D diagrams below should show how well the Dell 2209WA covers these colour spaces.

Explanation of 3D views: The black grid represents the respective standard colour space and the white grid represents the monitor’s colour space. The actual intersection of both colour spaces is represented by the coloured cube. When the black grid protrudes beyond the cube, the monitor’s colour space can no longer display the standard colour space. If the monitor colour space is larger than the respective standard colour space, the white grid protrudes beyond the cube.
