The monitor has 77% brightness and 50% contrast by default. I reduced them both to 39% to achieve a 100nit brightness of white. Increasing the contrast setting above the default value makes light halftones indistinguishable from white. Dark halftones remain visible at any value of contrast. Color gradients are reproduced well, without banding.
The brightness uniformity on white is 6.4% on average and 13.4% at the maximum. This is acceptable. For black, the numbers are 6.0% and 15.0% accordingly. Irrespective of the background color, the sides of the screen are darker than the center.
The gamma curves are not quite good at the default settings. The red and green curves are all right but the blue curve is sagging, resulting in inaccurate reproduction of colors.
When the contrast setting is reduced, the blue curve rises up to join the others. The monitor’s color reproduction is good at such settings.
There are only two preset color temperature modes. The temperatures of different gray levels vary by no more than 310K in the Warm mode, which is good. In the Cool mode the difference is over 1000K.
The monitor’s color gamut is just what you can expect from backlight lamps with ordinary phosphors. It coincides with the sRGB space in blues, is smaller than it in reds, and larger in greens.
To remind you, we measure the average time of pixel state transitions between various halftones, which produces a more realistic result than the measurement of the black-white-black transition only as in the ISO 13406-2 method. For LCD matrixes without response time compensation our measurement method produces a worse result than declared by the manufacturer (i.e. measured according to the ISO method). The AL1916W Asd is no exception. Its average response time is 15.1 milliseconds (GtG) due to very long transitions between halftones. The longest transition takes over 32 milliseconds on this monitor.
This model’s max brightness and contrast ratio are not record-breaking but sufficient for most applications such monitors are intended for.
Thus, the Acer AL1916W Asd may be interesting for people who want an inexpensive widescreen monitor and have little concern about its exterior design and matrix speed.
