REVIEW: Eizo S2242WH-GY Part 9

The brightness distribution on the Eizo S2242WH is merely satisfactory. In the central visual field of the screen, we were still able to measure a good result with a seven percent deviation from the starting brightness. At the lower edge of the screen, the average deviation in brightness is already nine percent. In the lower area of the screen, the deviations are too large with an average of 20 percent, with the brightness dropping especially strongly in the lower corners. On average, the deviation is 12 percent. The colour temperature, on the other hand, is very constant – although there are also peaks here. However, these values are only relevant to a limited extent as average values.

Although the deviation in brightness from the reference value is rather high, especially in the lower area of the screen, this does not appear in a negative light when viewed subjectively. The illumination is even and we did not notice any clouding or dark corners. Not even when a completely white image is displayed does a colour gradient appear. However, the backlighting is subject to a certain degree of variation within a series and the result can therefore be different even amongst the same model of monitor.

Viewing angle

Unlike TN panel monitors, the Eizo S2242WH, with its integrated S-PVA panel has a visibly large viewing angle; the manufacturer’s indication of 178 degrees is close to reality. Especially in image processing, which requires colour-stable work together with a stable viewing angle, the subjective image quality is better and colour hues and contrasts are stable for longer.

Even at very large viewing angles, the Eizo S2242WH provides good image display. Only the contrast is somewhat weaker and the colours thereby no longer look as saturated as from a central view. We rate the viewing angle dependency as very good.

Measurements and calibration

Next, we tested the colour accuracy of the Eizo S2242WH and determined 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 for these applications.

First, we measured the maximum colour space of the LCD and compared it with the ISO Coated printing colour space and the sRGB colour space. Because of the extended colour space of the Eizo S2242WH, we also carried out a comparison with AdobeRGB and ECI-RGB 2.0.

Colour space comparison

The sRGB colour space is the lowest common denomination for interaction between various input and output devices in the end-customer sector. If there is no colour profile for a device or graphics file, Windows automatically assumes sRGB. Many colour printers function on normal paper with the sRGB profile. 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 is generally the least that modern inkjet printers can manage. Many modern inkjet printers and printing processes cover an even larger area.

3D colour space comparison

The 3D diagrams below should show how well the Eizo S2242WH 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 coloured cube shows the intersection between the two. Where the black grid protrudes beyond the cube, the monitor’s colour space can no longer display the standard colour space. Where the monitor’s colour space is larger than the respective standard colour space, the white grid protrudes beyond the cube.

ISO Coated: 99.9 % coverages
