Having decided to purchase a modern LCD monitor, the future owner is faced with a huge selection of models.
The most obvious difference is the cost. Moreover, sometimes its formation, as it may seem, does not obey the
laws of logic. So, a monitor with a larger diagonal may cost less than with a similar model, but with a smaller screen. To a person who does not know
what a matrix of monitors is, this state of affairs seems strange. However, everything is natural. The price of the device is determined by a number of characteristics, including the manufacturer, scan frequency (for 3D images), and interfaces. The total cost is also affected by the matrix of monitors. This characteristic is inherent only in liquid crystal models and is not available in CRT technology. What is she like?
If we draw an analogy with the old display devices, then the matrix is the same screen bulb, the so-called CRT (cathode ray tube). It represents a huge number of pixel points that can transmit or filter light. The desired state is selected by the controller based on a computer command. Physically, the device looks like a rectangular plate. That is, the monitor consists of a control circuit and the screen itself (handset, matrix). Obviously, the price of the latter determines the cost of the entire device. As we have already indicated, the matrix of monitors differ not only in size (diagonal).
Most budget models use the TN variant. This is always indicated in the instructions and on the manufacturer’s website, so there are no problems with determining the
types of matrix monitors. TN technology allows you to produce
inexpensive screens that are characterized by high speed (low pixel translation time from one state to another). However, matrices for TN-based monitors are gradually starting to be squeezed out of the market by more promising alternative solutions. The reason for this is the known disadvantages of this technology:
- severe color distortion when viewed at an angle, and also in the vertical plane;
- poor display of black - it turns out with a grayish tint;
- color mismatch to the original. Although green remains green and blue remains blue, shades and their depth are disturbed.
On the other hand, for undemanding users who use a computer for games, movies and surfing the Internet, this is a pretty good solution.
Now many manufacturers offer a monitor with IPS-matrix at a very affordable price. Compared to TN, this technology offers much better color reproduction; extended angles at which the picture on the screen is not distorted. The disadvantages include the crystalline effect, when the image looks unnaturally smooth (it is recommended to see examples on the global network) and more high power. The reaction speed of pixels is inferior to this parameter in TN, however, at present, even what is there is quite enough for most tasks.
And the latest matrix technology is VA. In fact, it is a compromise between IPS and TN.
In addition to these three main areas, there are a number of modifications within each of them.
