How to choose a LCD Monitor?


LCD Monitor

Bored with your old monitor, you want something newer and better – the most advanced? You should choose LCD monitors, and we, in turn, show you what to pay attention to the selected monitor to meet your needs and serve you the true faith, as long as you do not decide to change it.
First of all, it should be noted that modern LCD monitors with different types of matrices, which affects all the other characteristics. To start with, what indices are characterized by a matrix, and then consider briefly the most important to the consumer characteristics of each type of matrix.
Characteristics of the matrix

LCD Monitors
The actual size of the screen is measured in inches. Unlike CRT monitors, LCD with the declared and the actual size of the diagonal is always the same. Because of this, the actual size of LCD-panel size of 15.1 “corresponds to the actual size of the 17” CRT monitor.
Angle. By this characterization, because of technological features, almost all LCD-technology CRT monitors are inferior. This is manifested in the fact that when looking at the monitor at a large angle, or the picture will be dark, or there will be a strong distortion of colors. However, some types of matrices for this indicator is close to that of a CRT.
Contrast ratio. This ratio is the ratio of the maximum and minimum possible intensity levels. In CRT monitors it is 500:1, which makes it possible to obtain the picture quality on the internet. Due to the fact that the light on the LCD backlight always on and can not be adjusted, then the main problem is to display black. Because of the technological features of LCD-panels, they are almost impossible to display true black. However, the developers are close to solving the problem and good contrast ratio LCD monitors at the moment is from 400:1 to 500:1.
Brightness is determined by the characteristics of the lamp. At this point on the LCD indicator is no different from the CRT, which is the standard for value in the 100 – 120 cd / m². Technically very easy to get a greater brightness value, but because it can significantly decrease the life of the phosphor.
Blind spots or pixel errors. because of faulty transistors, some pixels on the panel do not work. Ie a transistor ceases to adjust the light output by blocking in the open, always transmits light or closed. By the standards of tolerance of up to 5 pixel errors on the new LCD-panel.
The response time of liquid crystals – this is one of the most important characteristics of LCD-panels. Big time leads to a visible delay in fast moving images, such as the demonstration video. Normal rate should be less than 30 milliseconds.
The input signal and color. it must be digital, because otherwise, there will be a double digit conversion (GPU)-analog (VGA-connector) – figure (LCD-display), which reduces the image quality, especially in color.
Types of matrices
So, the following types of matrices:

LCD monitors Selection
TN – very inexpensive, and therefore the most common and popular form of matrices. In this type of matrices with respect to low power consumption and response time. The most important drawbacks – inaccurate color reproduction, low contrast, and a relatively small angle. Another disadvantage is that the “dead pixels” on these matrices are usually always burning.
IPS – in a given family of matrix are the best indicators of the viewing angle and color reproduction. But the response time and the contrast range in a very large range for different implementations of the technology. Usually, the response time of the matrices produced by IPS technology more than the matrix TN, and contrast – less than that of the matrix produced by technology * VA. Pixel errors IPS matrices usually lead to complete closure of translucency transistor, a pixel is black.
There are several modifications of IPS: S-IPS, AS-IPS, A-TW-IPS, H-IPS. Of these types can be distinguished A-TW-IPS, which is mainly used to create professional displays for publishing, and H-IPS – the latest modification of the technology.
* VA (Vertical Alignment) . Developed by Fujitsu, improved and modified in the future by different companies. This type of matrix – is a compromise between performance on most other types of matrices. Their main advantage – it’s a good color with a high contrast. All versions of this technology (MVA, PVA, S – PVA, S – MVA, P-MVA, A-MVA) created by different companies in order to improve certain characteristics of the parent technology, but, in fact, not too far removed from it in significant improvement in terms of performance
And, finally, some practical tips
If you work primarily with business applications, the most important factors when choosing a design and can serve as a price, because all the other features in this case are not critical. Is that when you buy a monitor with a diagonal of 20 inches, which will be used for working with tables and text, it is better to focus on models with a digital input (eg, DVI) for maximum image clarity.
If your work is more important color, the perfect choice for you to monitor matrix produced by IPS (better A-TW-IPS).
If not for the high price, the monitor with IPS technology would be well advised for home computers. However, all the same in terms of price and quality, the best choice for a universal home monitor is a monitor with modern technology * VA modification matrix. This matrix is in its characteristics satisfy both gamers who care response time, and the fans of video and photos, providing a more comfortable viewing movies and photos.

LCD-Monitors (LCD)
For those who prefer to spend their time while visiting the virtual 3D-worlds of modern games, a good option is to modern monitor with TN matrix, as it is the cheapest option, but in the games drawbacks of this technology practically manifested.
Given the choice between glossy and matte finish rely on their own personal experiences, as the pros and cons of these coatings entirely subjective.
When choosing between the standard and wide screen also can rely solely on subjective assessment. However, if you frequently use your computer for viewing DVD or HDTV, widescreen take – deeper feeling for beauty of picture quality. And, in addition, experts say that since the binocular field of view of the person closer to the aspect ratio to the same ratio of widescreen monitors, then, in theory, work on it has to be comfortable.
One last point – the comparison seems to be identical in characteristics, but different costs monitors pay attention not only to the production technology of the matrix, and additional functions that can substantially affect the price, but may not be useful for you. It is a built-in speakers, microphone, camera, various additional I / O, etc. Also, in recent years, an important role in the formation of prices has played a design decision.
Good luck to you to choose LCD Monitor!
