REVIEW: NEC EA261WM-BK Part 7

Measurements and calibration

We then tested the colour fidelity of the NEC EA261WM and checked how well the LCD monitor could be calibrated. The results are mainly of interest for graphics and photo editing. They are negligible for office use and games, since here, the subjective impression is more important.

Next, we measured the maximum colour space of the LCD monitor and compared it with the ISO Coated printing colour space and the sRGB colour space.

Colour space comparison

sRGB is the lowest common denominator for 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 work using the sRGB- profile on normal paper. This is also why the sRGB colour space is significant for "normal users", unlike the ISO Coated colour space. Because of the increase in the use of digital mirror reflex cameras and in amateur photography, photo services have also switched many of their exposure machines to the sRGB colour space in order to save their customers from, having to use special colour space.

The comparison of the monitor’s colour space with the ISO Coated colour space used in offset printing is also interesting, since this represents the minimum most inkjet printers can manage. Many modern inkjet printers and printing processes also cover an even larger area. The ISO Coated colour space is covered 100 percent by the EA261WM.

ISOcoated: 100 %

3D colour space comparison

We also measured how well the NEC EA261WM covered various colour spaces. The sRGB coverage is important for normal users. On the other hand, AdobeRGB is of interest to graphics workers and photographers, as is ECI RGB 2.0.

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 between both colour spaces is illustrated by the coloured cube. Where the black grid protrudes beyond the cube, the monitor’s colour space can no longer display the standard colour space. If the monitor’s colour space is larger than the respective standard colour space, the white grid protrudes beyond the cube.

sRGB: 96 % coverage

AdobeRGB: 94 % coverage

ECI-RGB 2.0: 88 % coverage

ISO Coated is covered perfectly at 100 percent. The sRGB colour space is covered very well at 96 percent by the EA261WM. In the sRGB sector, the monitor meets our expectations, at least in terms of colour space. The good results in the AdobeRGB colour space were surprising, with a good 94 percent coverage, as were the still satisfactory 88 percent coverage of the ECI-RGB 2.0 colour space. The monitor was not marked expressly as a Wide Gamut display, and the result was surprising considering this. We then clarified to what extent colour-accurate work could be carried out in the respective colour spaces.
