Matrix Monitors

You go to the store, choose a monitor. You, of course, want to choose the best one, one that will suit your needs. But they show the same picture, and, in general, everything looks fine. What, the choice of the monitor remains a matter of taste? If you think so, yes, but the characteristics of the monitor, which make their properties different, still there.

In general, these characteristics: viewing angles, color rendition, brightness, contrast, response time, screen size, interface connection and, of course, design. Believe me, sometimes design is the decisive factor in buying. Meanwhile, it is he who pulls on himself hardly half the cost. Another price, or rather the overpayment affects the company manufacturer, or rather the brand. In terms of monitor maintenance, as in the maintenance of computers - all models are about the same.

Monitors and matrixes of monitors

At the time of electro-beam monitors there were no matrices . There was a kinescope and a different design of the fluorescent mask. Right now, for the correctness of color transmission, the brightness, contrast, response time parameters are just matrices of monitors. Now there are several types of monitors, but the most common is TN + Film. All monitors on one matrix are approximately the same in parameters and differ only in design. In fact, this is not entirely true, but for the consumer, the changes in these characteristics are not very noticeable.

TN + film, although the cheapest and rather mediocre matrix (in comparison with others), but still for everyday work is suitable for the ratio of price and quality. However, it does not suit everyone and not everyone.

Let's analyze the merits and demerits of different matrices.

• TN + film (Twisted Nematic + film). Film is a layer of film that increases some of the matrix's performance. Monitors on TN are interesting primarily for low price and high speed of crystal response. On this type of matrix is best implemented function overdrive (sometimes it is called otherwise), designed to just increase the speed of response. But there are also minuses: it's bad viewing angles (the color changes depending on the angle at which you look at the monitor); Color rendering, which does not cover even the minimum acceptable color space; Low contrast.

• IPS (In-Plane Switching). The favorite matrix of designers, so from the very beginning of production, had close to the electron-beam monitors color rendering parameters and good angles. Contrast and brightness significantly depend on the technology used to implement the matrix. Meanwhile, IPS have a longer response time than TN and slightly worse contrast than the PVA or MVA matrix. IPS now has several varieties that affect the quality of the picture:

• S-IPS (Super) implements a shorter response time;
• AS-IPS (Advanced Super) - improved contrast;
• TW-IPS (Advanced True White) - Improved color reproduction, in particular, improved the reproduction of white.
• H-IPS is the latest version of the matrix. Improved contrast.

• * VA (PVA, MVA) is a matrix that is implemented as something between TN and IPS. It has decent angles, excellent contrast, good color rendering. Angles are better than TN, but worse than IPS. Now there are several varieties of VA:

• MVA proposed by LG;
• PVA - technology development by Samsung;
• And also their further development of S-MVA and S-PVA, as well as P-MVA, A-MVA.

As you can see, each of these types of matrices has its own merits and demerits. Which monitor to choose? TN today is a universal choice, especially for gaming computers. Designers still prefer IPS. Well, of course, you can - if you find - use the house * VA, as a kind of compromise.
