By default, the monitor has 100% brightness and 50% contrast. I achieved a 100nit brightness of white by selecting 20% brightness and 23% contrast. Brightness is controlled by means of pulse-width modulation of the power of the backlight lamps.
Color gradients are reproduced quite well. You can discern stripes in them, but they are not very conspicuous and won’t show up at everyday work.
The use of an S-IPS matrix brings you good and bad things at once. On one hand, its viewing angles are superb. You can take a look at the screen from a side and the image will only lose a little in contrast and nothing in color reproduction. On the other hand, there is a violet hue, typical of S-IPS technology, on a black background as soon as you deflect your line of sight from strictly perpendicular to the screen. This is not a fatal defect (to me, it’s better to have that violet than the narrow viewing angles of some TN+Film matrixes), but it is conspicuous even if you are not specifically looking for it.
The monitor’s matrix has a glossy coating. It looks cool in a shop window, but is not very practical. Depending on the position and brightness of light sources in your room, you may see flares, reflections and other irritating things on the screen.
Having a superb shape, the monitor’s gamma curves nearly coincide with the theoretical ones. The monitor reproduces all color tones, and it does so even at the reduced contrast, but only until you make use of a DV Mode. Moreover, you shouldn’t increase the monitor’s contrast setting above its default value of 50%. If you do, the matrix will stop to distinguish between light tones and will display them all as pure white.
The MultiSync 20WGX2 offers an impressive (for the class of inexpensive home monitors it belongs to) selection of preset color temperatures, as many as six of them! Each preset is very accurate, there is a very small difference between the different levels of gray.
The MultiSync 20WGX2 indeed turned to have an RTC-enabled matrix inside. This is the first monitor tested in our labs to have an accelerated S-IPS matrix. According to my measurements, its average response time is 6.6 milliseconds with a maximum of 10.0 milliseconds. So, the 20WGX2 is faster than models on MVA and PVA matrixes (among which the Acer AL2032WA with an average response time of 8.5 milliseconds stands out) and is close in speed to modern monitors on RTC-enabled TN+Film matrixes.
The RTC error is small on average, only 3.1%, but reaches 58.2% at the maximum, on a transition from black to dark gray. It means that you’ll see an annoying silvery trail behind moving objects in some of dark scenes in movies and games. You won’t see this too often, though, because the error is really big only on a few transitions.
The contrast ratio of this monitor is average, just a little above 250:1 at the maximum (I mean the contrast of static images, of course). The max brightness is very high enabling you to watch movies even under bright daylight. A majority of users won’t use even half the brightness this monitor can offer, I guess.
So, the MultiSync 20WGX2 leaves a good impression. NEC has created a home/games-oriented monitor that combines a fast matrix with excellent viewing angles and accurate color reproduction. On the downside are the stand that doesn’t permit to adjust the height of the screen, the relatively low contrast ratio, the characteristic violet hue of the S-IPS matrix, and the glossy screen coating. However, people who are looking for a universal home monitor that would suit equally well for games/movies and for work, also for processing photographs, should certainly take a look at the 20WGX2. I think it won’t disappoint you.
