The red and green curves are almost perfect at the default settings, but the blue curve is higher than necessary.
We’ve got the same curves at the 100nit settings because I only reduced the Brightness setting to achieve the 100nit white. But since this setting changes the brightness of the backlight lamps, it has no effect on color reproduction. If you try to reduce the Contrast setting, the screen gets too dark.
Interestingly, the gamma curves retain their shapes even at the maximum Brightness and Contrast. This is a rare thing indeed. It means you can use the monitor at a high brightness of its screen. Just don’t forget that the ambient lighting must match the monitor’s screen. Otherwise your eye will get tired too soon.
There are few color temperature modes to choose from and their setup is not very accurate. There is no really warm or really cold mode, and the difference between the levels of grays is over 1000K. Darks are noticeably colder than lights in every mode.
The CIE diagram not only confirms what I’ve said above but also indicates a deflection towards green. It is not as strong as to be disturbing at work, though.
The monitor’s color gamut is quite standard for a model with ordinary backlight lamps. It is larger than sRGB in greens and differs from it in reds.
The response time average is 15.4 milliseconds (GtG) with a maximum of 32.6 milliseconds. This is a normal speed for a matrix without response time compensation. RTC-less matrixes can be faster, but cannot match RTC-enabled models anyway.
The maximum brightness and contrast ratio are not high at the default settings. As opposed to most other monitors, you won’t have to lower these settings in the menu – the monitor is originally set up for comfortable brightness. Of course, it also offers a reserve of brightness of games and movies. The maximum value is about 250 nits, which is normal for a modern monitor.
Now let’s check out the preset image modes.
These modes are set up quite properly, especially for people who prefer to work under dim ambient lighting. The screen may prove to be insufficiently bright in the Text and Movie mode for a well-lit office room. The contrast ratio is not very high, either.
In each of the preset modes color reproduction remains the same as at the default settings.
Summing it up, the Acer AL1917Nsd is a cheap multimedia monitor without obvious defects. However, it has a number of small drawbacks such as a low contrast ratio, unassuming exterior design, average color accuracy, and a slow matrix.
- Low price
- Good setup of the preset modes
- Slow matrix
- Low quality of color temperature setup
- Nonuniform black brightness
- Text-based applications (documents, spreadsheets, Web)
