REVIEW: Dell 3008WFP Part 10

Comparison of sRGB mode with sRGB standard

sRGB monitor profile	sRGB standard	measured
White point / Kelvin	6500	6150
Brightness / cd/m²	140	147
Black point / cd/m²	0,00	0,20
Contrast / x:1	Native	734
Gamma / average	sRGB (~2,2)	1,95

With the sRGB monitor profile, the grey gradient display is somewhat poorer than in the factory settings. However, White Point and Cyan are better. With an average deviation of 5,3 deltaE and a maximum deviation of 10 deltaE, the result is acceptable for most users who do not have calibration tools, apart from the gamma value, which is too low.

Comparison of calibration to sRGB with sRGB standard

sRGB colour profile	sRGB standard	measured
White point / Kelvin	6500	6550
Brightness / cd/m²	140	140
Black point / cd/m²	0,00	0,20
Contrast / x:1	Native	699
Gamma / average	sRGB (~2,2)	2,17

After calibration, the average deviation is at an acceptable level of 3.2 deltaE and only Green and Cyan demonstrate larger deviations. In view of the fact that extended colour space models generally tend to have difficulties displaying the small sRGB colour space, the result for the Dell 3008WP is very good.

sRGB settings: Brightness = 22, Contrast = 50 (standard), Red = 96, Green = 91, Blue = 100. The values are only meant as guides and cannot replace calibration.

Comparison of calibration to AdobeRGB with AdobeRGB standard

AdobeRGB colour profile	AdobeRGB standard	measured
White point / Kelvin	6500	6550
Brightness / cd/m²	120	120
Black point / cd/m²	0,00	0,20
Contrast / x:1	Native	599
Gamma / average	2,2	2,18

When calibrated to meet the demands of AdobeRGB, the 30-inch model plays out its strengths and recommends itself with a very good result: the average deviation is just 1,8 deltaE and the maximum deviation is under 5 deltaE.

Settings: Brightness = 4, Contrast = 50 (standard), Red = 96, Green = 92, Blue = 100. The values are only meant as guides and cannot replace calibration.

Comparison of calibration to ECI 2.0 with ECI 2.0 standard

ECI 2.0 colour profile	ECI 2.0 standard	measured
White point / Kelvin	5000	5050
Brightness / cd/m²	120	120
Black point / cd/m²	0,00	0,20
Contrast / x:1	Native	599
Gamma / average	Lstar	2,17

When it comes to colour fidelity in ECI 2.0 environments, the Dell model demonstrates larger deviations of 8.2 and 10 deltaE for Red and Blue. However, the average deviation of 3.5 deltaE should be satisfactory for many users.

Settings: Brightness = 8, Contrast = 50 (standard), Red = 100, Green = 88, Blue = 82. The values are only meant as guides and cannot replace calibration.
