REVIEW: Dell 2709W Part 6
In this section, the setting options for OSD language, transparency and display timer can be found. In addition, the DELL 2709W has an "LCD Improvement" mode. Here, large surface RGM filler colours are displayed alternately in order to "eliminate burned-in image" and make locked pixels function again. According to the manufacturer, this tool should increase the lifetime of the monitor considerably where the quality remains perfect.
Here, the user has the option to link the direct menu buttons individually to different functions. Here, a positive aspect to mention is the option to adjust the gamma value. The DELL 2709W offers the choice between PC and MAC gamma. The change between "Graphics" and "Video" is also possible. In Graphics mode, the model attempts to function with more colour fidelity, whilst in video mode, saturation and subjective impression are in the foreground.
The OSD stands out in terms of its enormous size and new-style controls. It is transparent in many parts and allows the screen background to shine through. In addition, the transparency of the OSD can be determined manually. Controls are simple and leave nothing to be desired.
In our test, the automatic recognition of the signal sources worked very sluggishly and energy-saving mode was activated too quickly when a source was not found. Here Dell should have acted with other time values in order to increase user-friendliness. In addition, a better thought out PIP function would have been desirable where the selection of signal sources is concerned.
The S-PVA panel used in the model provides very good subjective image quality. Colours look very vivid and homogeneity and illumination are acceptable at first glance. Brightness is set to 50 percent in the factory settings and is too bright. This can only be corrected to a limited extent by reducing the brightness value. Even at 0 percent brightness, the brightness value is 145 cd/m², which is still too high for normal usage in dark rooms and for the achievement of most required calibration settings. If you use the model in locations where the surroundings are more brightly lit, the high level of brightness is more useful, since it allows an image to be achieved which is richer in contrast and detail.
We measured the brightness distribution at 15 points after reducing the brightness to 0 percent in order to reach the lowest value of 145 cd/m². The remaining brightness was reduced via the graphics card in order to achieve the target value of 140 cd/m².
The measurement results were measured at 15 points.
The average brightness distribution can still be rated good at about 12 percent. Here, the gamma value varied between 2.2 and 2.3. However, overall, the image is homogenous.
