Our settings
| Black levels: | 0.07 cd/m² |
| ANSI contrast: | 2753:1 |
| Average gamma: | 2.36 |
| DeltaE on PC: | 3.4 |
| Energy consumption (model tested): | 128 W |
We take these measuements using the best settings for watching a movie. Cinema mode is generally the one we use. To recap, black levels should approach zero, contrast be higher than 1500:1, the DeltaE remain uder 4 (ideally 3) and the gamma curve be as close as possible to 2.22. Wherever possible, we set the white levels at 160 to 180 cd/m².
This TV is the 40 inch version of the Bravia KDL-46W5500 that we have tested.
For the rest, its spec is identical on all points to the model tested and we can therefore expect to find the same results on this model. Sometimes however, manufacturers do equip different sized versions differently with different panels. If this is the case, the results published here will not apply to the different panels. Contrast, black levels, colours and ghosting will all be subject to notable differences on different panels.
And for those who use the same panel for all sizes, they give strictly identical results, except for brightness which can vary very slightly from one size to another, which can affect contrast. We have been able to check this in testing and our results have been confirmed by those manufacturers we have consulted on the subject.
Pluses
-
Excellent contrast
-
Good ergonomics overall (menus, on-screen manual, remote )
-
Variety of settings
-
Effective 100 Hz Motionflow
Minuses
-
Reduced angle of vision (the blacks get lighter)
-
No 200 Hz Motionflow
The W5500 is the uncontested successor to the W4500. Only the narrow angle of vision for blacks may discourage some viewers.
