What is a computer monitor?
A computer monitor, also known as computer screen, is a peripheral computer device that shows moving 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.
There are two specific types of computer monitors; CRT and LCD. LCD (Liquid Crystal Display) monitors are energy efficient computer monitors that come with a variety 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 charge liquidized crystals that are located between two plates of glass. Fluorescent tubes provide the source of light and this passes 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 people are opting for the less bulky and lighter LCD Monitor.
A CRT monitor works the same way as your household television. It is usually very bulky and heavy. The cathode in the monitor works by shooting an electronic beam through the vacuum tube that is also located in the monitor. The vacuum tube sends out phosphors that create 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 person 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 determine the size and capabilities of the monitor you need to purchase.
Next, determine 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 determine 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 perfect for small areas.
What kind of resolution and display size is needed? When the sales person 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 generally 2-3 times less expensive then an LCD monitor but will provide you with less display area.
Last, determine exactly what size monitor you need based on what you intend to use it for. Computer monitors come in a variety of sizes and it will be a matter of what you want, need and can afford.
Happy Computing!
