Acer AL1911

The design of this display resembles that of some models from Hitachi. I am not sure who is the creator of the design, but the fact is certain. The distinguishing features of the Acer are the cute silver buttons and the integrated speakers. The display has only one input – D-Sub.

The base allows you to change the tilt of the screen as well as to turn it by 45 degrees in both directions. The portrait mode and height adjustment are not available, but this is not a big deal. The base is quite compact, and the screen is not too high up. And I doubt you would ever need to raise the big 19” screen.

The menu is pretty, colorful and easy to use. The color temperature can be set to one of the four values: User (manual adjustment), 6500K (the measurements showed that the real color temperature in this mode is 5810K for white color and 7350K for 50% gray), 7500K (the measured temperature of white is 6570K, while gray is 9420K) and 9300K (7930K white and 9820K gray). As you see, the temperature of the gray color is noticeably higher than it should be. It means that the white balance being optimal, gray will have a hint of blue. I performed the tests using the 6500K setting. After calibration, the color temperatures of white and gray were 6420K and 6960K, respectively.

By default, the brightness setting was at 100%, the contrast – at 50%. This is my first reference point. The second reference point is a screen brightness of 100nit (1 nit = 1 candela per square meter). To reach it, I had to drop the brightness control to 40% and the contrast to 33%. The measurements also showed that the display’s brightness is managed by pulse-width modulation of the backlight lamp with a frequency of 150Hz.

The viewing angles are good, but not perfect. If you look at the screen at a big angle, the image becomes dark and the colors become yellowish. Still, the effect is not too heavy to make you feel uncomfortable.

At default settings, the color rendition is stable, although the measurements proved my suppositions expressed above: the blue color is considerably higher in the middle part of the range than it should be.

At 100nit screen brightness, things become worse. The red color characteristic is “wavy”, while the blue color has a “hump” in the middle of the range. At the same time, the display represents the entire dynamic range well enough. It doesn’t fail on light tones at the default screen brightness or on dark tones at the minimal acceptable screen brightness (save for red, maybe).

The response time coincided with the specification: 15ms pixel rise time and 11ms pixel fall time. However, at 100nit screen brightness, the pixel rise time suddenly grows by 10ms.

The maximum brightness of the display falls a little short of the specified 300nit mark. The contrast ratio is considerably lower than 700:1 claimed in the specs. The level of black is not very high, but is far from perfect. It’s rather average compared to other displays.

Overall, the Acer AL1911 is a good model with a small (for a 19” display) response time, nice color rendition and unobtrusive design. This display will be a good choice for both home and office use.
