19” LCD monitor survey: 4, 8 ms, TN, IPS, VA…

ViewSonic VP191b
We already wrote an article on the VP191b. We felt however that it would be unfair not to include this monitor in this list since it has the potential to be a winner.



First of all, we remind you that ViewSonic had the bad idea of keeping the same name as one of their previous monitors, instead of finding a new one. The result was quite a mess in shops. To spot a new 8ms version, a third generation, you need to look for a sticker placed on the right side of the box:

Color quality
The VP191b was tested before the new color evaluation procedure. Like for many other monitors, the test before calibration didn’t work, so we only reported the one made after:



How to interpret the graph

On the left is the gamut this is the monitor colorimetric range compared to the sRGB range (the one usually used for digital cameras). This doesn’t correspond to the accuracy, but to the range of reproducible colors.

For accuracy, you have to refer to the right graph, the DeltaE. This is a measure between the color requested and the one really displayed on the monitor. The result obtained is also counter-balanced by human color sensitivity.

With Delta E > 3 the desired colors is noticeably different from the one on the screen.
With 1 < Delta E < 2 colors are accurate. With Delta E < 1, the result is perfect.

Just as a reminder we made this test with all , IPS, MVA and Lumileds panels here. The comparison of this graph with the other ones shows the HS95P’s good results . Its gamut is very close to the sRGB colorimetric space. Compared to this space, we usually find a little weakness in the blue compensated by a good green level. The DeltaE graph is better than any of the five reference monitors.

It is very good. It is hard to find anything to say about these results.

Games, movies

Fast, the VP191b is really faster than the previous VA generations. The comparison with TN monitors show, however, that TN still are slightly faster. The Iiyama E480S, for example, with the Samsung TN 8 ms panel has, in practice, a lower reaction time. It is the same for the Samsung 913N and Hyundai L90D+ of the previous roundup, including TN panels. It is also consequently slower than the VX924, but the VP191b doesn’t have flow issues like the other monitor. It is also faster than the C19-4, including the same panel, and is a lot faster than MVA 8 ms based on the Fujitsu panel.

Even if it isn’t the fastest monitor, this excellent behavior will please almost all gamers. I say almost all of them, because there are still a few users who will continue to claim the superiority of CRTs (and it is true) and won’t go near an LCD monitor.

After a couple of hundreds of LCDs test, and hours spent playing with all sort of monitors, our conclusion is that its reaction time is very good, and it is even possible to play FPS games.

About movies, and we already said that before, this monitor features twinkling effect in dark areas but has a good image quality for the rest.

Verdict
The color quality is very good, it features very rich ergonomics for a general user monitor. The monitor design is rather dated, but its reaction time, its ergonomics and viewing angle are such that this monitor is finally, the most polyvalent on the market and our favorite for the moment.
