Things to Consider Before Buying an LCD Monitor

By Victor Thomas

An LCD monitor is the abbreviation for Liquid Crystal Display monitor. The quality of the images produced in an LCD monitor is high and it has high brightness and contrast levels as well.
There are various things to be checked while working with such a monitor. One of the things to be checked is the number of USB hubs that such units have. These hubs usually come with the display at an extra cost. They prove to be useful if plugging the USB devices in the computer is difficult. The next thing to be considered is the warranty on the backlight. This backlight is an important component in the display as it transmits the light into the display. In some cases, the monitor might have a longer warranty, but the backlight would be given less warranty, which means that if it wears away, then the whole screen has to be replaced at the cost of the user. So it is always good to look for a higher warranty on the backlight.
Sometimes, when the same colour or page is left on the screen for long, it develops those pixels present there to get worn out and thus becomes dead. This develops a black or white dot on the screen, thus avoiding that particular area to produce any image. This, at times, might be due to the manufacturing defect also. Hence it is better to look for warranties on all these issues. Some monitors come with an attached speaker system. This is usually expensive when compared to the separate speaker system. If such an attached speaker system is available in the monitor, then it should be noted that a quick-mute button and readily accessible volume controls should be available in the monitor itself.
LCD monitors emit less of electro-magnetic radiations, when compared to the CRT monitors. The effect of electro-magnetic radiations on the human body and how hazardous to health it is, is not yet found out. The main thing to be checked while going for such a model is the aspect ratio that it provides. For computer monitors, the ratio usually seen is 4:3. Also, for higher clarity and picture-perfect levels, there are higher aspect ratios. This is mainly dependent on the resolution provided by the monitor. There are monitors that produce resolution of 800x600p, 1280x1024p, which gives an aspect ratio of 5:4. For works that need high resolution and quality, it is better to go for high resolution monitors.
LCDs take very less desk space and also are quite good in terms of quality and clarity of images. Also the energy consumed by them is very less and since the electro-magnetic radiations emitted are also less, it is also less hazardous to health. Taking all the above things into consideration, it can be purchased and taken care of. Also these points help in avoiding many misconceptions that users have on LCD monitors.
