The red and green curves are good at the default settings but the blue curve is sagging.
The blue curve rises up to normal level at the reduced settings.
The color temperature setup is good in every mode. The temperature dispersion is within 1000K in the Cool mode and within 500K in the other modes. I guess the only thing this monitor lacks is a really cold mode, with a color temperature of about 9300K.
The dots are always higher than the white curve in the diagrams. Thus, the VK191D is going to produce a yellow-greenish hue, noticeable in gray.
The color gamut is standard. I can only note that the monitor’s reds are very close to those of the sRGB color space. There is usually a bigger discrepancy between them. Anyway, this improvement can hardly be noticed without a calibrator.
The response time average is 13.7 milliseconds (GtG) with a maximum of 28 milliseconds. That’s quite a normal speed for an RTC-less TN matrix.
The maximum brightness and contrast ratio are satisfactory at each of the three variants of settings. The contrast ratio is even higher than 600:1 in one mode, which is just excellent for a TN matrix.
Now let’s check out the image presets referred to as Splendid technology.
Well, they are no good, actually. It’s nice to have a high contrast ratio, but why is every mode so bright?
Color accuracy is low in the Splendid modes. Each of them has gamma curves similar to those of the diagram above (the diagram was built for the Scenery mode). The contrast setting is too high, making 20% of the lightest halftones indistinguishable from white.
Thus, the ASUS VK191D would be just a regular widescreen 19-incher if it were not for its integrated web-camera with surprisingly high image quality. As a monitor proper, this model is no different from others of its class. If you communicate via Skype often, you may be interested in the VK191D. Otherwise, it can hardly be an interesting buy.
