REVIEW: Iiyama ProLite B2206WS-B1 Part 6
Brightness distribution was measured at 15 points.
At the same time as the deviations in brightness, sometimes, deviations in colour temperature can be seen in some monitors. Not even calibration to 6500K guarantees that this white point is retained at least to a certain extent.
Thus, we also measured the deviations in white point at 15 points on the screen. Since this is not a monitor for graphics workers, however, we will not bother with the graph that goes with this section. The maximum deviation from the value in the centre is in the lower left corner at 591 Kelvin.
The maximum brightness was measured in the colour temperature "Standard", so without adjusting the colour channels. Long waiting times are not necessary for moderate changes, since the monitor applies the desired values quickly and easily.
At 297 cd/m², the model misses out narrowly on the manufacturer’s specification of 300 cd/m². This brightness is naturally more than sufficient and should be reduced considerably for daily usage.
With the low bottom limit of 67 cd/m², not only can all normal calibration goals be achieved, but even users who wish for a monitor with a low brightness level will be pleased. As soon as the primary colours are lowered in the course of a calibration, the minimum possible brightness is also reduced. The level of brightness that PRAD recommends (140 cd/m²) was achieved on the test model using the following settings:
Red: 65, Green: 65, Blue: 70, brightness: 40, contrast: 70, Gamma mode 3.
The display of grey wedges and colour gradients is also not evenly divided in the factory settings and demonstrates clearly visible banding.
Here, it should be mentioned that the various gamma modes offered by the manufacturer do not match the description correctly. Whilst the manufacturer indicates that Mode 1 is the normal case and Gamma mode 3 is "high contrast", it has emerged that Gamma mode 3 offers the lowest levels in the grey wedge and offers a gamma value of 2,22 in the factory settings. Gamma mode 1 is 2,6 and Gamma mode 3 even offers a value of 3.
The photo presented unfortunately does not show the banding established in as pronounced a manner as can be seen with the naked eye.
Banding is already visible in the factory settings without adjustment (visible in the enlarged view).
The monitor is absolutely silent.
With response times of two milliseconds, this TN panel is one of the fastest on the market according to the data sheet and is therefore certainly fast enough for games, videos and films.
Such low response times are often bought using aggressive overdrive processes, which bring about negative effects such as ghosting and corona effects and thus do not lead to an improvement in display.
This is not the case with the Iiyama ProLite B2206WS. In all synthetic tests, the display was always perfect. If an overdrive solution has been implemented here, this is very well controlled and does not cause any negative effects.
