The monitor has 50% contrast and 90% brightness by default. I achieved a 100nit white by selecting 70% brightness and 40% contrast. The monitor regulates its brightness by means of backlight modulation at a frequency of 387Hz.

The monitor’s color gamut is just what you can expect from ordinary backlight lamps: it is somewhat larger than sRGB in greens, smaller in reds, and coincides with it in blues. The diagram shows that the point of white of the NEC monitor (marked with a white circle) is shifted towards greens a little.


The average nonuniformity of white brightness is 6.3% with a maximum deflection of 17.2%. For black brightness the average and maximum are 6.1% and 20.5%, respectively. The numbers are not very good. The pictures show that the center of the screen is brighter than its sides, and there are brighter areas along the top and bottom of the screen on the black background.

The gamma curves are acceptable at the default settings. The blue curve betrays an exceedingly high level of contrast while greens are lighter than they should be. Anyway, these drawbacks are not critical, especially for an entry-level monitor.

The gamma curves improve at the reduced brightness and contrast. Now they lie close to the ideal curve for gamma 2.2 which is black in the diagram.

The color temperature setup is sloppy. The grays differ by 1000K in every mode, and the Warm mode is not warm at all. It yields a color temperature of 7000K and higher and most users will perceive this as neutral or even cold (with a bluish hue), but not as warm. On the other hand, if you disregard the temperatures of white, which are not insignificant if you work at a reduced level of contrast, the Warm and sRGB modes are going to be quite satisfactory.

The monitor’s brightness is somewhat higher than 200 nits. This is normal for a modern model and quite suitable not only for office applications but also for movies and games even under daylight. The contrast ratio isn’t high. Most modern monitors, even TN-based ones, have a better level of black.

The response time average is 14.4 milliseconds (GtG) with a maximum of 21.9 milliseconds. And I have to remind you that TN-based monitors with a specified response time of 4 and 5 milliseconds actually differ threefold, not by 25%, in terms of real speed. Why? 4ms monitors feature response time compensation technology and their response time is measured according to the GtG method whereas 5ms monitors do not have RTC and their response time is measured according to the ISO13406-2 method which has little to do with reality. I use the GtG method in my tests for all monitors as it provides the most accurate picture.

Summing it up, the LCD22WV is far from impressive. It can be purchased as a simple monitor for working with text and watching movies. Its low price is the single advantage but there are quite a lot of alternatives in the entry-level sector. You should consider other models if quality is important to you.
