NEC MultiSync LCD1760NX

This model participated in one of my first reviews of LCD monitors on our site – it was the first monitor with a specified full response time of 16 milliseconds. Unfortunately, this was its only advantage then – the matrix from AU Optronics was no good at reproducing colors and didn’t provide acceptable viewing angles. However, the currently selling samples of the LCD1760NX have visually better parameters, so I decided to give it another chance. And really, the monitor now uses a 16ms matrix (LM170E01 model) from LG.Philips LCD instead of an AUO matrix.

The monitor is made in an angular and somewhat bulky case, typical for NEC. The case is functional as you can adjust the height (almost from zero) and tilt of the screen and rotate it around the vertical axis, but some users are repelled by the unassuming looks of the device. The portrait mode is not available.

The LCD1760NX is equipped with an analog and digital input; the power adapter is integrated into the case.

The buttons are made of white plastic in this sample, so the pressed-out labels are readable, although with some effort. In models with a black case it is practically impossible to read the labels when you’re setting the monitor up.

The menu follows NEC’s standard style, which can be characterized like the monitor itself as “not very beautiful but usable”. Quick buttons give you quick access to the brightness and contrast settings as well as to the auto-adjustment feature, but there are still no presets in the LightView or MagicBright style.

By default, the brightness setting is set to 100%, the contrast – to 50%. By choosing 33 percent of brightness and 37 percent of contrast I reached 100nit screen brightness. The signal from the photo-sensor clearly shows modulation of the backlight lamps at 190Hz frequency in this case.

The menu offers six color temperature variants, and four of them (save for “sRGB” and “Native”) permit a manual adjustment – you can control the RGB sliders independently, and even this option can be of some help if you often switch between color temperatures, but none of the presets satisfies you. At the default settings, as my measurements showed, the color temperatures of white and gray were:

  • 7410K and 7870K in the “1” mode (the monitor informs you that this mode should correspond to a temperature of 9300K),
  • 6880K and 7290K in the “2” mode (which is supposed to give you a temperature of 8200K),
  • 6470K and 6820K in the “3” mode (which should be 7500K),
  • 5870K and 6090K in the “sRGB” mode,
  • 4870K and 5000K in the “5” mode (5000K) and
  • 6430K and 6730K in the “Native” mode.

So, the real color temperatures are lower than the ones reported by the monitor, but the difference between the temperatures of white and gray is rather small.

The color-reproduction qualities of this monitor are very good. Unlike with the earlier-tested sample with the older matrix from AUO, I could find no visual artifacts. The viewing angles are quite typical as modern TN matrixes go (and much better than those of the LCD1760NX with the older matrix). The horizontal angles provoke no discomfort at all, but as for the vertical, you can always see that the top of the screen is slightly darker than the bottom. By the way, the manufacturer specifies viewing angles of 160 degrees, but mentions that they are measured by the contrast ratio drop to 5:1, rather than to 10:1, as usual. In other words, we have 140-degree angles, but measured in a different way.

The gamma curves have a neat shape, save for a noticeably low blue color (that’s why the real color temperatures are lower than reported). Moreover, the monitor cannot differentiate between a few dark-blue tones, but their amounts doesn’t grow up at low brightness levels, like it was with the LCD1703M, since the brightness is controlled with the backlight lamps. In fact, the gamma curves have the same shape at 100nit screen brightness as in the above graph (i.e. at the default settings of the monitor).

The response time measurements were a pleasant surprise: the repose time turned to be 12ms (9+3ms) instead of the specified 16 milliseconds! Thus, it looks even more confusing with the monitors from LG: although the company has a 12ms matrix at its disposal, it is currently supplying monitors with 16ms matrixes. On the other hand, the graph indicates that the new matrix from LG in the NEC monitor is faster than the older one, but not too much – the pixel rise time is over 25 milliseconds at the maximum.

The contrast ratio of this monitor reached 400:1. That’s a very good result for a TN+Film matrix. What’s important, the screen brightness was small at that – and good contrast is most needed at low brightness levels.

Thus, the LCD1760NX has got rid of the image quality related problems the first generation of “fast” matrixes was guilty of. Having a matrix from LG, this model surpassed the “native” monitors of the LG brand in the characteristics. The downside is the exterior and functionality – the LCD1760N can’t boast a portrait screen mode, brightness/contrast presets or elegance and compactness of the case.
