The gamma curves are not good at the default settings. The red and green curves look good but the blue curve is sagging.

When the brightness and contrast settings are reduced to produce a 100nit white, the blue curve gets higher.

Anyway, the color temperature setup is very good in every mode save for Cool: the temperature dispersion is within 500K. In the Cool mode the temperature varies by 1500K.

The CIE diagram shows that the monitor has a considerable greenish hue. Fortunately, the deflection towards green is small in the Normal mode which is going to be preferred by most users.

The monitor’s color gamut is standard and does not need any comments. The majority of monitors with ordinary backlight lamps provide the same color gamut.

As I said above, this model lacks response time compensation. Its response time average is 14.1 milliseconds (GtG) with a maximum of 25.1 milliseconds.

The monitor doesn’t set any records when it comes to maximum brightness and contrast ratio. It is similar to typical 19-inch TN-based models in this respect and is going to satisfy most users.

Now let’s check out the factory-set Splendid modes.

The contrast ratio is good but the default screen brightness is too high for most applications.

The diagram above shows the gamma curves in the Game mode (they are similar in the other modes). The Contrast setting is too high, which makes the lightest halftones indistinguishable from white. The curves differ in shape, so there is no talking about color accuracy.

Thus, the ASUS VW198T is one of the few 19-inch monitors with a small pixel pitch. Like the VW198S from the same series, this model has good viewing angles and good color temperature setup. It differs for the better with its digital input but has somewhat worse gamma curves. The VW198T may be a good buy for people who prefer small pixels and high resolutions but who won’t buy a larger monitor for some reason.


  • Good viewing angles (for a TN matrix)
  • Increased native resolution
  • Good color temperature setup


  • Slow matrix
  • Poor setup of the Splendid modes

Recommended usage:

  • Text-based applications (documents, spreadsheets, Web)
  • Viewing and simple editing of photographs
  • Movies and games that don’t require a fast matrix
