LCD MonitorsBuying a new monitor is fun, as well as it involves some level of expertise. It isn’t only about how big a screen is, or how flat a monitor is. There are a lot of factors which should be kept in mind before buying a monitor. You should be sure about what exactly your needs are, how much space can your desk allow for a monitor, and how much can you spend on getting a new display. All these factors, combined with few others are very important to keep in mind before you go out to the market and fetch a monitor home.

Today, we shall provide you with some useful tips to follow, and keep in mind before going to buy a monitor. Once you know exactly what should be important to note, you can go shopping alone and quite confidently.

1. LCD Displays:

LCD displays are very common these days, and are available in a variety of sizes and forms. There are a lot of factors involved behind the inclination of people towards these displays.

Size: It is an important factor to note. The entry level LCD monitors begin from 17” to 19”, usually. These are sometimes paired with inexpensive PC deals. These displays have usually an analog video input only, and no digital video input, thus they are quite simple to use. For ordinary office work and web browsing purposes, these monitors work quite well, provided they offer fine resolution and screen adjustments.

Professional level LCD monitors have usually wider screen. They offer better image quality via digital inputs; usually DVI. Other features include better image adjusting controls, integrated USB ports and memory card slots, a larger set of ergonomic options, higher resolutions, asset control, and hardware calibration. Few pro LCDs provide color-calibration tools, too.

Native Resolution: LCD display consists of two glass-plates holding inside them an arrangement of liquid crystals. Two glass-plates hold thousands of pixels filled with liquid crystals, and there is a source of light at the back. There are two transparent electrodes and two polarizing filters also; between them is present a layer of molecules. Liquid crystal molecules are lined up in a certain direction before an electric charge is applied to them. When an electric charge is applied, variation results in construction of different levels of grey. Colors are subtracted from white light and thus, color elements are displayed.

Most of the 17” to 19” LCD displays use native resolution of 1280-by-1024, 23” to 24” have 1920 by 1200, and 30” have 2560 by 1600. Do not forget that you can never exceed an LCD’s native resolution.

Aspect Ratio: It is the relationship of screen’s width to screen’s height. These days, an ideal ratio is 16:9, which is perfect for working in large spreadsheets, programs that contain many toolbars or palettes, to view documents or two Web pages side-by-side, and for watching movies.

Viewing Angle: It indicates how far you can move to the side, above, or below from the center of the display before the image quality depreciates to intolerable levels. There isn’t any industry standard method for measuring this angle. Best way to decide is by having a close look at the monitor. Discard any option having a viewing angle below 150 degrees.

Contrast Ratio: It refers to the brightest and darkest light values that a display can generate at a time. Do not settle for anything less than 400:1 and above 600:1. Here, too, no industry standard measurement means exist. Below 400:1, you will have either too washed out colors, or too darkened screen with the screen adjustments you make.

Brightness: This feature measures the greatest amount of light that comesLCD Displays from a screen displaying pure white. 250cd/m2 or above is the most suitable and useful level, which will work well for you. Note if the brightness level can be adjusted or not.

Special Inputs: These days, people attach a lot of gadgets with one another for different purposes. It would be better if you buy such a monitor which is fully equipped with special inputs such as S video ports, memory card slots, component and composite input, and HDMI ports.

Response Time: Basically, there are two main types of LCD response time. Rise-and-fall response time measures the time it takes a pixel to turn from black to white (rise) and then back to black (fall). Gray-to-gray response time measures the time it takes for a pixel to change from one shade of gray to another. It varies from brand to brand. Most of the LCD displays have fast response time.

Physical Adjustments: You must check out if the monitor you are interested in can be adjusted at different angles or not. This is a very important aspect to keep in mind while buying a monitor as one has to make many adjustments during working.

So, these are the basic points upon which your decision to choose a monitor must depend. Do check the working of your object before buying it, as precaution is better than cure.
