The sRGB colour space is almost completely covered at 99 percent. This is a very good value.
AdobeRGB: 98 % coverage
The AdobeRGB colour space is almost completely covered at 98 percent. This confirms an enormous and cleanly set up colour space which the Dell 2408WFP offers.
ECI-RGB 2.0: 93 % coverage
Even the ECI-RGB 2.0 colour space is extremely well covered at 93 percent and was a completely positive surprise. The Dell 2408WFP not only demonstrated an extremely large colour space in fact, but can also prove that this is well adjusted and is therefore excellent for extended colour space coverage.

deltaE deviation
Explanation of deltaE deviation: Deviation in colour values is measured in deltaE 94 (dE). Several grey gradients, the primary (RGB) and secondary (CMY) basic colours are measured. A deltaE value of 1 represents the smallest difference in colour which can be perceived by the human eye. Most people recognise a difference in colour from a value of 3. However, our eyes are more sensitive to green tones, so that even smaller differences can be perceived here. The average deviation should be lower than 3 dE and the maximum should be under 10 dE, or, better still, under 6 dE. Up to 10 dE, two colours are still sufficiently similar.

In the factory settings, the Dell 2408WFP already delivers a halfway magnificent result apart from the excessively high brightness. We reduced the brightness to 0 percent for the measurements and established that the colour deviations and also the contrast ratios are not changed. The required white point is almost exactly matched at 6536K. The gamma value is somewhat too high at 2,36. The deviations in the colour values are high, even if you consider that the model is a wide gamut monitor. With an average deltaE of 4,8, it is still possible to work with the monitor, provided that you reduce the brightness to 0 percent.
