The monitor’s color gamut is just what you can expect from a model with ordinary backlight lamps. It is somewhat wider than sRGB in greens but smaller in reds.
The response time average is 13.6 milliseconds (GtG) with a maximum of 22.1 milliseconds. This is the speed you can expect from an RTC-less matrix.
The contrast ratio is very good at the maximum settings and just sufficient in the other test modes.
Like other monitors from ASUS, the VB191T features Splendid technology, a set of predefined image modes you can switch between by pressing a single button.
The Splendid modes are rather close to each other by default, except for the Night View mode that has a high level of black. Well, this mode is meant for very dark games where the brighter black will help you better spot an enemy lurking in shadows.
Color reproduction is no good, though. The curves are shaped like this in every made save for Standard. The blue curve has an S-shaped twist and differs from the other two. The curves do not go near the theoretical curve, either. Thus, you can’t have correct color reproduction in any of the Splendid modes. This is actually a common problem of all ASUS monitors we have tested in our labs.
Summing it up, the ASUS VB191T is a typical representative of the class of inexpensive 19-inch TN-based monitors. It has neither special advantages nor serious defects and will satisfy an undemanding user.
- Good color temperature setup
- Slow matrix
- Text-based applications (documents, spreadsheets, Web)
- Movies and games that don’t require a fast matrix
