NEC MultiSync LCD1850E
This display is relatively out-dated, but you can still find it in the market for about $580. It looks bulky compared to the models of the last generation with its wide plastic housing and big depth caused by the integrated power unit. The base allows tilting the screen and rotating it by 170 degrees in both directions. The portrait mode is not supported. There are two inputs, but both of them are analog. Newer LCD models with two inputs usually have one DVI port.
The display’s menu is of average user-friendliness, but all the necessary options are present. The brightness and contrast are not assigned any quick buttons. Quick access is only for switching between the inputs. The remaining buttons simply open the main menu.
By default, the brightness is set to maximum, and the contrast to 50%. The color temperature is set to “Native”. As our measurements showed, this means 6630K on white and 6870K on gray. When I switched to 6500K color temperature, measurements gave out 6040K on white and 6130K on gray. The tests were performed with the color temperature setting of 6500K.
The brightness of the display is controlled by power modulation of the backlighting lamps, but unlike the current NEC models, the modulation frequency is only 150Hz here. Having set both brightness and contrast controls to 50%, I got 100nit screen brightness.
The color curves at default settings have a perfect shape; the blue and green colors are just a little higher than necessary. Calibration is no problem here. After it, the image becomes warmer as the color temperature grows to 6360K and 6420K (white and gray, respectively).
The same curves try to keep their shape at settings with the low brightness (100nit). Green does it all right, while red and blue lose some of the dark tones.
The manufacturer says the display response time is 50ms (30/20ms). In practice, it is lower (18/21ms) when the contrast is at maximum. The brightness is regulated by the backlight lamps and doesn’t affect the response time. As for the contrast, I got 29/24ms response time by reducing the contrast down to 50%.

The maximum screen brightness is a little lower than the promised value, while the contrast ratio may even exceed the specification at some settings. For example, it is over 500:1 at 100nit screen brightness.
Although this model is being ousted from the market by the LCD1860NX series, it is quite capable of competing with much younger displays due to its good color rendition and excellent level of black. However, people who are sensitive to screen flicker should pay attention to the low frequency of the backlighting modulation.
