The brightness of white varies by 3.9% on average, reaching a maximum deflection of 18.9%. There are brighter spots at the sides and center of the screen. For black, the average brightness uniformity is 6.2% with a maximum of 22.1%. The whole screen is covered with spots of varying brightness. That’s not an awful result, yet most monitors perform better in this test.


The gamma curves are good at the default settings, differing but slightly from the theoretical curve. The blue curve is just slightly different from the others.


The gamma curves get even closer to each other at the reduced settings. The monitor has no problems with the reproduction of darks.

The monitor’s color temperature setup is far from perfect. There is a small difference between the different grays in each mode, except for Cool where the temperature dispersion amounts to over 1000K, but white is considerably warmer than any gray. And the main problem is that the monitor doesn’t offer a really low-temperature mode. You will have to manually adjust the RGB levels to get rid of the characteristic blue tint.

The monitor’s color gamut is quite what you can expect from a model with ordinary backlight lamps. It is wider than sRGB in greens and smaller than it in reds.

The response time average is 14.1 milliseconds (GtG) with a maximum of 25.5 milliseconds. These are typical values for TN matrixes without response time compensation. The response time is indeed 5 milliseconds if measured according to the ISO 13406-2 method, i.e. for the white-black-white transition, but halftone transitions take three or four times as long as that.

The brightness of white is satisfactory but the contrast ratio is lower than with most other monitors. Now let’s check out the factory-set image modes.

It is good Acer has reasonable notions about what brightness and contrast ratio are desired for different usages of the monitor. Every mode is set up appropriately to its name.


It is also good that color reproduction doesn’t suffer in the factory-set modes. The gamma curves have nearly ideal shapes in them as the diagram shows (for the Graphics mode).

Overall, the Acer AL1916W Ds is a typical entry-level monitor with typical drawbacks such as an unassuming exterior design, slow TN matrix and the lack of digital input. It differs from same-class models with its predefined image modes which are set up very well, but has nonuniform black brightness and sloppy color temperature setup. This monitor will do just fine for simple work at home or in the office, but it has a lot of opponents in its class. Choosing among them is a matter of what drawbacks you are ready to put up with in your monitor.


  • Inexpensive
  • Good setup of the factory-set image modes


  • Slow matrix
  • No digital interface
  • Sloppy color temperature setup (every mode is too cold)
  • Low uniformity of black brightness

Recommended usage:

  • Text-based applications (documents, spreadsheets, Web)
