Make sure your monitor is fit for the job

Considered to be the ‘eyes’ of a computer, the PC monitor is an often neglected peripheral, with people giving little thought to their selection. Indeed, in most cases, the manufacturers have already made the decision for you, with many included for ‘free’ when you buy a computer. However, according to experts, careful consideration should be given to choosing a monitor since it is the only means of seeing what’s going on inside your computer.

Generally speaking, there are two main types of PC monitor: cathode ray tubes (CRTs) and liquid crystal displays (LCDs). A CRT uses similar vacuum tube technology to that seen in a traditional television set, and is known as an emissive display.

Employing the use of red, green and blue phosphors, light is created on the screen’s surface through three electron guns, which are placed at the back of the picture tube. These guns send electrons towards the front of the tube, which activate the phosphors, making them glow. Different colours are created according to the strength of the electron beams, which are controlled electronically. This also means that the speed and location of them can be adjusted, so that different resolutions are displayed.

In comparison, an LCD monitor has a transmissible display, with its light source provided for by a bright backlight. Images are created when the individual liquid crystal cells either block or transmit light, whilst colour comes from red, green and blue filters.

LCDs come in two main categories – passive matrix and active matrix – with the difference between them affecting the overall image quality: active matrix LCDs provide sharper images and are considered better for displaying moving images. The passive matrix ones, however, are simpler and therefore cheaper to build.

With the advancement of technology, LCD monitors are becoming increasingly popular. However, there is still a market for the CRTs. Indeed, not only are they a cheaper option, but they are capable of displaying more colours than their LCD counterparts. Additionally, they are known to react faster and display moving images more effectively.

On the other hand, LCDs are much more compact and consume less energy overall; an important factor for the environmentally conscious. Not only that, but the image tends to be sharper than that of the CRT and because the screen doesn’t flicker, eye strain is reduced. They are the more costly option, however.

With pros and cons for both types of PC monitors it is essential that you determine how you use your computer, in order to make the best choice when purchasing one. Budget and space will of course also play a deciding role.

There are a few tips, however, that the experts believe you should follow: opt for the biggest display that both your budget and space available will allow. Furthermore, always check the warranty – three years is the best option; and make sure you are clear on the resolution of the display. And, once you are clear on what each PC monitor has to offer, you can then precede to purchasing the monitor that best meets your personal requirements.
