The average white brightness uniformity is 5.3% with a maximum of 15.6%. For black, the average and maximum are 6.1% and 17.9% respectively. The screen is getting darker from the center towards the edges. The numbers are not particularly good, but there are no conspicuous zones with different levels of brightness on the screen.
The gamma curves betray a low value of gamma at the default as well as reduced settings. They go above the theoretical curve as the result. The image is whitish and low-contrast, especially in darks.
The curves retain their shape at the maximum settings and go above the theoretical curve again. In other words, you can change the contrast setting without fearing to lose light halftones as is the case with most other monitors.
The color temperature setup is high quality. The temperature dispersion is within 500K in every mode. There is no really warm mode (with a color temperature below 6000K) but this monitor’s sRGB mode is closer to the required 6500K than in the above-discussed monitors from ASUS.
The color gamut is interesting. The monitor’s triangle is about the same size as usual but it is larger in greens and smaller in reds than a typical color gamut of LCD monitors.
The response time average is 15.1 milliseconds (GtG) with a maximum of 23 milliseconds. This is a normal result of an RTC-less TN matrix but I’ve seen faster models. Anyway, if you need a really faster matrix, you should look for RTC-enabled models such as the ViewSonic VX1940w, which has a high-resolution matrix, too.
The monitor’s contrast ratio is normal for a TN matrix.
And again I wouldn’t recommend you to use the Splendid modes as they are set up by default. Every mode is way too bright, so you may want to adjust them manually.
However, color reproduction is poor in each mode, much worse than when the Splendid feature disabled. For example, in the Game mode the lightest halftones, about one fifth of the entire dynamic range, are displayed as the same color. The curves also differ much from each other.
The other modes are but slightly better. The Theater mode has problems with lights due to excessive contrast and the curves have odd wavy shapes that also differ from each other.
Thus, the ASUS VW198S is an interesting product with an increased native resolution, improved viewing angles and good color reproduction setup. On the downside are the lack of a digital interface and the poor setup of the Splendid modes. If you prefer monitors with a small pixel pitch and don’t have much money to spend, you should certainly consider this model.
- Good viewing angles (for a TN matrix)
- Increased native resolution
- Good color temperature setup
- Slow matrix
- No digital interface
- Poor setup of the Splendid modes
- Text-based applications (documents, spreadsheets, Web)
- Movies and games that don’t require a fast matrix
