REVIEW: Samsung 226BW Part 10
The dynamic contrast is modified one the one hand by automatically adjusting the gamma value so that the best possible contrast ratio can be attained. The Samsung 226BW’s MagicColor function is also used in this regard and it also takes the user-defined settings into account. On the other hand, the backlight can also be regulated depending on the screen content by selecting the Optimal Contrast option.
For images that are predominately very bright, the brightness is increased additionally. For predominately dark images, the brightness is reduced so that in the ideal case, the advertised contrast ratio of 3.000:1 can be achieved. The wallpaper screenshots show the result: the Samsung 226BW conjures up particularly splendid, gloriously colourful pictures on the desktop on request.
Comparison of activated dynamic contrast (above) and our user-defined settings without artificial contrast increase (below).
However, the dynamic contrast of the Samsung monitor is mainly intended for video playback and should be enjoyed with some caution. The reason why becomes clear when you look more closely at certain parts of the screen. When the gamma curve is changed to heighten the contrast, colour tones are generally lost as a result.
The result is colour and grey gradients with clearly visible. In addition, in the case of some colour combinations, a pixel block effect becomes visible. The brightness is much too high for office work and some users will be unhappy with the colours, which sometimes appear artificial. The Optimal Contrast mode is also unsuitable for games, since the backlight darkens abruptly after quick changes from bright to dark game scenes, which affects the fluency of play.
Left: Out user-defined image setting. Right: When the contrast is heightened artificially, colour tones are lost so that some colour gradients display clear levels or –as can be seen in the picture- a pixel block effect.
Therefore, it is good that the user can deactivate the dynamic contrast comfortably and change into the user profile or another image mode at the touch of a button. Samsung shows real initiative here since before or after the strengths of the monitor also come to the fore after the user settings have been modified and the Samsung 226BW delivery an image experience that is subjectively very good even without the contrast ratio of 3000:1.
