What is a Computer Monitor?

A computer monitor, also known as computer screen, is a peripheral computer expedient that shows piquant or still images that have been generated by the computer and processed by the graphics card in the computer. There are several display standards in the monitor that define how the images are viewed on the computer monitor.

Let's have a look at computer monitors.

Laser Printer Price

There are two exact types of computer monitors; Crt and Lcd. Lcd (Liquid Crystal Display) monitors are energy efficient computer monitors that come with a range of benefits.

An Lcd monitor, in general, is compact, thin and lightweight. The way an Lcd monitor works is comparable to how a digital watch works. It contains transistors that payment liquidized crystals that are located between two plates of glass. Fluorescent tubes contribute the source of light and this passes straight through one layer of the liquid crystals. Typically, an Lcd monitor will have a longer life-span, less heat output, save on space and is energy efficient.

A Crt (cathode-ray tube) monitor is still the most common type of computer monitor. They have been used for many years, but more population are opting for the less bulky and lighter Lcd Monitor.

A Crt monitor works the same way as your household television. It is commonly very bulky and heavy. The cathode in the monitor works by shooting an electronic beam straight through the vacuum tube that is also located in the monitor. The vacuum tube sends out phosphors that generate the glow seen on the monitor screen.

Questions to ask before buying a new monitor.

When shopping for a new computer monitor, you should ask the sales man a few questions prior to handing over your hard-earned money.

First, ask yourself how you intend to use the monitor. Will it be for gaming? Work? This will help you rule the size and capabilities of the monitor you need to purchase.

Next, rule where the monitor will be located. Will it be on a desk that sits flush with the wall? Or is the desk in the middle of the room? Is the desk small or large? This will help you rule the size of the monitor and whether you need a Crt monitor or an Lcd monitor. Remember a Crt monitor is large and bulky while the Lcd monitor is exquisite for small areas.

What kind of resolution and display size is needed? When the sales man tells you the display size of an Lcd screen, it will be the exact size he says. With a Crt monitor, you can expect the display size to be about an inch smaller.

If price is a factor, then the Crt monitor will work well for you. It is ordinarily 2-3 times less high-priced then an Lcd monitor but will contribute you with less display area.

Last, rule exactly what size monitor you need based on what you intend to use it for. Computer monitors come in a range of sizes and it will be a matter of what you want, need and can afford.

Happy Computing!
