NEC MultiSync LCD1860NX

You can guess the manufacturer of this display at once by its “angular” style. It has the common problem of all black-colored LCDs from NEC – the captions on the buttons are practically unreadable. The base allows you to change the height and tilt of the screen as well as rotate it around the vertical axis. To perform the first two actions you will have to apply some physical strength (especially for the tilting), while the rotation is performed with ease: I even had to hold the screen in place to push a button. The portrait mode is unavailable, unfortunately.

The display has two inputs – D-Sub and DVI; you switch between them by pressing a button on the front panel.

The menu follows the standard NEC style, so I won’t describe it in detail, since we have already discussed it in our previous articles on the subject. There are six settings for the color temperature: 9300K (when measured, it turned to be 8040K on white and 8140K on gray), 8200K (7310K and 7470K), 7500K (6610K and 6830K), sRGB (in theory, this should mean 6500K; in practice, it is 5840K on white and 5760K on gray), 5000K (4540K and 4530K) and Native (this is the default setting, meaning 6080K on white and 6020K on gray). You may notice that the LCD1860NX has a smaller white and gray color temperatures dispersion compared to other displays. The difference doesn’t go beyond the measurement error in some cases. This may mean only one thing – the color rendition of the display has been carefully set up. Well, this is typical of displays from NEC.

I carried out my tests using the Native setting as it was the closest to the required 6500K. After calibration, the color temperature for white was 6560K, for gray – 6660K.

By default, we have the brightness set to 100%, the contrast to 50%. To reach a screen brightness of 100nit, I dropped the brightness to 70%, and the contrast to 45%. Note that the brightness is controlled by the power modulation of the backlight lamp with a frequency of 150Hz. The modulation is evident even at the maximum brightness. The reason for that is not clear – further reduction of the modulation depth would give the manufacturer an opportunity to increase the maximum brightness higher up without any effort.

The graphs drawn with the help of the calibrator show that the color curves don’t coincide with the theoretical one, but the slumps and peaks for all three color components fall onto the same brightness stretches. Thus, all gradations of gray will look as they should do, without the bluishness in the middle of the range, typical of many displays.

The situation remains practically the same when we reduce the screen brightness:

Although the specified response time is 30ms, the display can do it in less than 25ms almost throughout the entire range. Only when the contrast is reduced, the pixel rise time grows to 20ms.

The brightness of the display is below average – only 185nit. Most modern models have a brightness of 220…250nit. The level of black is good, although not excellent. Anyway, you should not worry that you will see dark-gray instead of pure black on this display.

As you see, the major distinguishing feature of the LCD1860NX is very precise color setup. This display actually needs no color profile. Other parameters are at an average level. This model may suit those of you who need a low-cost display with good color rendition.
