This model has more uniform brightness of the backlight. The average white brightness uniformity is 6.9% with a maximum of 18.5%. For black, the average and maximum are 6.3% and 19.9%, respectively. That’s more acceptable than the results of the previous model. The pattern on the screen hasn’t changed, though. The bottom center of the screen is still brighter than the rest of it.
The gamma curves are close to each other at the default settings but their value of gamma is smaller than 2.2. This results in a somewhat whitish image.
There are no big changes at the reduced settings except that the value of gamma is even lower now. The gamma curves go higher than the theoretical one, resulting in a whitish image.
The color temperature setup is high quality. You are offered a broad choice of modes. And the temperature dispersion is within 500K in each mode.
I guess you are not surprised to see this monitor have the same color gamut as the ViewSonic VA916. Why should it change if the difference between these two models boils down to one connector and minor variations in setup?
The response time is somewhat higher but the difference fits into the measurement error range. It may be due to the variation in the parameters of matrixes from the same batch. So, the response time average of this model is 13.6 milliseconds (GtG) with a maximum of 22.2 milliseconds. That’s not very fast.
The contrast ratio has changed somewhat, too. It is higher in one test mode and lower in another, but that’s not a fundamental difference. Both models from ViewSonic are quite satisfactory in this parameter for most applications.
Thus, the ViewSonic VA928 is in fact a VA916 but with a digital interface. Otherwise, their parameters are very similar. The VA926 offers more uniform backlight brightness, but somewhat worse color reproduction. The difference is indeed very small and may be due to the variation of parameters between different samples of the same matrix. I guess this monitor is somewhat more interesting than its DVI-less version, but there are so many worthy alternatives in this product category that I wouldn’t predict it a huge market success.
- Good color temperature setup
- Low brightness uniformity, especially with black
- No factory-set image modes
- Slow matrix
- Text-based applications (documents, spreadsheets, Web)
- Movies and games that don’t require a fast matrix
