NEC AccuSync LCD71VM

The case of AccuSync LCD71VM is designed in the traditional “square” style from NEC, but the face view differs: the front panel is silver-colored, the buttons have been moved from the bottom rib of the case to the framing, and the two speakers are located on both.

The framing around the screen is thin, but you can’t call the case compact: it’s really larger than usual. The low-profile wide base makes the box very steady, but only allows changing the screen tilt.

The settings menu is far from being user-friendly. First, you can see the current settings (like brightness or contrast) only after you have entered the corresponding submenu as the main menu page informs you about the resolution and refresh rate and that’s all. Second, you can leave the menu either as a result of time-out or by scrolling to the “EXIT” item: there is no separate button for this. Third, the monitor cannot memorize the position of the cursor when you leave the menu. Fourth, I couldn’t find an option for changing the menu position on the screen. Among the advantages of the menu, I should point out the possibility to reset each of the settings independently rather than all together. You can quick-access the brightness (the “-” button) and the speakers volume settings (the “+” button).

Four color temperatures are available: user-defined (default, it means 6170K for white and 7880K for gray), “6500K” (corresponds to 6240K and 7920K; as you see, this doesn’t differ much from the default user-defined setting), “7500K” (the temperatures are 7480K and 10,580K), and “9300K” (this sets the temperature of white to 9110K and of gray to 14,320K).

The horizontal viewing angles are average. White becomes yellowish at an angle of 45-50°, but the image loses its contrast at a larger angle, so the manufacturer can honestly write 140° in the specifications. As usual, it’s worse with the vertical angles: whatever your position is, the top of the screen will be a little darker than the middle, while the bottom will appear too light. This effect shows itself in its full beauty when you’ve got a gray background. However, it is also perfectly seen in an ordinary text processor: the toolbar above is darker than Windows’ Taskbar below.

The monitor is good at auto-adjustment (it takes only about 2 seconds, by the way). The color reproduction is beyond criticism: a smooth color gradient is reproduced excellently.

The default brightness and contrast are 100% and 50% correspondingly. To make the screen shine with a luminosity of 100nit, I dropped the brightness control to 21%. It means that you can just reduce the brightness to work comfortably in a dim room. Brightness is regulated by power modulation of the backlight lamp with a frequency of about 280Hz.

Note also that when the contrast is the highest (and that’s the settings I used when measuring the response time), the monitor reproduces about 10-15% of light-gray tones as a pure white.

However, at the default settings and at 100nit screen brightness, the color reproduction is close to perfect. The measured color curves are merging with the reference one.

The response time doesn’t exceed the specified 16msec on black-to-white transitions, but it goes as high as 30msec and more on black-to-gray transitions. This is one more proof to my point that 25msec matrixes remain strong competitors to newer 16msec matrixes.

From level of gray = 192, there is a sudden slump of the pixel rise time. This is due to the above-mentioned fact that the monitor cannot distinguish between light-gray tones at the maximum contrast and reproduces them as white. So, in practice, when the contrast is lower, this small response time will only be achieved on transitions from black to white and very close to white tones.

The contrast ratio is not that bad as it seems from the table below. As you see, the level of black at 100nit screen brightness is very low and only exceeds 1nit when the brightness is close to its maximum. A screen brightness of 250nit is too much for many situations, and the user is likely to reduce it below the default value, thus reducing the level of black and increasing the contrast ratio.

AccuSync LCD71VM is an inexpensive model from NEC, which cannot be considered an advantage. The menu is pretty clumsy, the case is designed as very “square” and harsh, and color temperature setup is simply horrible. The 16msec matrix used in this model cannot give it any advantage over slower 25msec matrixes from other manufacturers. The price of AccuSync LCD71VM may become an appealing factor for you to buy it, but take a look at other options first.
