The menu is standard but doesn’t offer the Advanced DV Mode. An entry-level monitor isn’t worthy of such advanced features.

By default, the monitor has 100% brightness and 50% contrast. To achieve a 100nit brightness of white I reduced both brightness and contrast settings to 30%.

Color gradients are reproduced well on this monitor, but with a barely visible banding. This is not a gross defect, though.

The gamma curves are acceptable. They deflect from the theoretical ones, especially the blue curve. When the contrast setting is reduced in the monitor’s menu, the curves improve somewhat, but are still far from perfect. On the other hand, the monitor honestly reproduces the entire color range at the default settings as well as at the reduced brightness/contrast (unless you touch the DV Modes that distort the reproduction of colors, as they always do).

There are many and well set-up color temperature modes here. The difference between the levels of gray is small. Although the real temperature values may differ from the option names in the menu, choosing from six options instead of two or three helps easily select what suits you most.

The LCD2070WNX indeed lacks response time compensation, yet I measured its response not only on black-to-gray transitions but also on all gray-to-gray ones in order to compare it with RTC-enabled monitors. Alas, the result isn’t encouraging: an average response time of 16.6 milliseconds (compare this with the NEC 20WGX2’s 6.6 milliseconds or with the Acer AL2032WA’s 8.5 milliseconds) with a maximum of 37.3 milliseconds! This is very far from the specified 10 milliseconds.

Perhaps we’ve got an old and slow TN+Film matrix here? Here’s a 2D diagram that helps compare this monitor with those that we tested earlier on our site.

So, the matrix is fast. On this diagram, the maximum is a little above the 25 milliseconds mark which I long considered an excellent result. So, the LCD2070WNX once again illustrates the effect from response time compensation technology. Having a matrix that would have been considered rather fast just a little time ago, it is now two or more times slower than RTC-enabled monitors. Moreover, the Acer AL2032WA and the NEC 20WGX2 are based on matrixes that have traditionally been viewed as slower than TN+Film, but the introduction of RTC technology has made this view obsolete.

The monitor’s contrast ratio is average, or even below the average, at only 200:1. So, there’s nothing more to comment upon.

My tests suggest that it would be wrong to associate the LCD2070WNX with the older LCD2070NX model or with the new 20WGX2. This monitor has a TN+Film matrix with rather small viewing angles and a not very high speed due to the lack of RTC. Low price is usually the main feature of such products, but the LCD2070WNX doesn’t look winsome from this point of view, either, because it is about $50 more expensive than its main competitors (BenQ FP202W, Samsung 205BW, etc). There’s nothing exceptional about the monitor’s parameters. It is oriented at office applications and at undemanding home users who won’t bother about its small viewing angles and rather low speed. Demanding users should better consider the MultiSync 20WGX2, the senior model I have tested above.
