How to Select the Right LCD Monitor


Some tips that can serve as guidelines for selecting the type of LCD Monitor LCD needs to be sought. Specifications listed may help us to know the kind where we need.

1. Screen Size. As with choosing a type of CRT monitors, we first determine the diagonal size of the CRT monitor, CRT monitor with an average size of 17 has about 15-16 diagonal viewable only. In contrast to the size of the diagonal size LCD monitors that it has a diagonal viewable 17 as well. In other words its LCD viewable area 17 effectively equivalent to a CRT monitor 18 & 19 •. Some LCD screens also have a kind of wide / wide (16:9). For gamers and the hobby of watching movies, with a widescreen LCD is perfect but it must also be supported by the VGA in your CPU. Make sure you select the type and size of the display accordingly. For now, the LCD 15 and 17 seem to be the favorite because the price is more affordable.

2. Native Resolution. LCDs are generally only work on one resolution only, namely its native resolution. Excluding the resolution, usually becomes the maximum display quality, especially in the text. Will reduce the size of the LCD screen or performing interpolation to compensate for the use of non-native resolutions. This will reduce your comfort in using the LCD. Therefore, make sure you buy a LCD with a native resolution of your most frequently used. LCD 15 generally has a native resolution 1024x 768 pixels, while the LCD 17 has a resolution of 1280 x 1024 pixels.

3. Brightness. Brightness or luminance (light levels) is a parameter that indicates the brightness of a monitor. Knowingly or not, in a dark room you might tend to like a slightly dim screen (so that no glare and fast eye fatigue). Conversely, in conditions of a well-lit room, you tend to set the brightness at a rather high position. The goal is to be able to display images with clarity and not inferior to the lighter room conditions. Level of brightness or luminance typically has units of cd/m2 (candelas per square meter). CRT usually have about 100-150 cd/m2 luminance, while LCD is usually above 200 cd / m2. Notice also the uniformity or flatness level of brightness on the screen. Supposedly, the upper left of the screen will have the same brightness with the brightness at the bottom right, as well as in other parts. Generally, the LCD has a better uniformity than the CRT.

4. Contrast Ratio. Contrast ratio itself is a comparison of the darkest black to brightest white color. The higher the contrast ratio, ideally would be better because of gradation from black to whitest white terhitamdengan higher. Contrast ratio is simply can be obtained from the whitest white to the black division terhitam. Indirectly, the contrast ratio will depend on the brightness as well. The effect, producers tend to increase the brightness to get the whitest of white values as high. This could have a negative impact because the brightness is too high tends to make out the color becomes too high Brightness is also sometimes made of black color shift to gray. The best result is if the manufacturers can provide high brightness for high value whitest whites, while still maintaining a low value terhitam black. Unfortunately, not many LCDs that can do this. So, as a consumer you should not be too awed by the promise of contrast ratio or high brightness. Also make sure the contrast ratio and high brightness, the monitor display is still fit for use (in the sense of color is not a wash-out just because of brightness raised too high).

5. Response Time. Response time is a unique thing which is only possessed by the type of LCD monitors. To form a color, each crystal in the LCD pixels will be energized. These currents will change the conditions of the crystal, could be a condition of state or vice versa. Response time is the time required by the crystal to change the condition of being off 'or vice versa. Off to the crystal condition of on.disebut as rising time, while from on to off condition is often referred to as the falling time. Rising time is usually faster than the falling time. The slow falling time tends to leave a ghosting effect on the screen, especially on the display screen refresh requiring fast (like the scene quickly in games or movies). This will usually be one of the early weakness LCD output. New generation LCD with response time under 16 ms is generally not a problem ghosting. Another Note: LCD is not affected by refresh rate. This is due to the working principle of using crystal LCD on / off button, not refresh the screen. LCDs generally have 60 or 75Hz refresh rate, and this factor does not affect comfort, such as on a CRT display. Figures also show that response time is often a factor that can be sold to prospective customers. Manufacturers usually only put so many ms response time, but not explained is the response time when the crystal changes from what color to what color. Changes from white to black may take x ms. However, the change from white to red color could be more time consuming. Two LCD with the same response may have a different view of quality, depending on the color change is happening.

6. Viewing Angle. Early-generation LCDs generally have a narrow viewing angles. Display will be dark when viewed from the side slightly oblique. New generation of LCDs have wide viewing angles, even very large. Some LCDs are tested can be seen from a very wide angle (more than 70 degrees from one side, or 140 degrees horizontally). There are even claiming the LCD viewing angles up to 89 degrees horizontally from one side (or up to 178 degrees from the left-right). One negative side of the viewing angle is too wide is your display easier to see or diintip by coworkers.

7. LCD connector allows images sent from the video card via a digital connector. Common connector for the LCD is Digital Visual Interface (DVI). If the video card and your LCD supports DVI, then use these connectors can provide a better display quality. In addition, some OSD settings will also be done automatically when you use DVI. This will facilitate the setting. Without the hassle, you can simply enjoy the excellent display quality. For those of you who are less fortunate, then the analog D-sub connector commonly used on the CRT can also be used.
