Refurbished computer monitors give value for money. Most of the times, a refurbished monitor is a new monitor returned by the customer. Manufacturer checks the monitor and stamps it as a refurbished monitor.
The Computer Monitor is essential and important part of any computer system. Monitor and graphics card forms the display which requires almost 25 % of the total cost of the computer. Hence we will have to be very careful while selecting the monitor.
Computer Monitors available in the market are capable of displaying 16.7 million colors with resolution of up to 1600 x 1200 pixels. Now a days even 22 inch monitors are available in the market. Due to mass production, prices of monitor are falling down.

CRT computer monitors are heavy and bulky. CRT computer monitors require more power. Their high voltage electric field, magnetic field and radiation are harmful to the user. Scanning technology used in computer monitor produces flickering which is harmful to eye. LCD computer monitors are compact and require less power. LCD computer monitors are costlier compared to CRT computer monitors. The typical problem in LCD monitors is you cannot view the screen from some angle. You have to view it from the front side only. Because compact size and low power, it has become de facto standard in Laptops. Now days more and more LCD monitors are used, due to its compact size and elegant look.
Buying tips for Refurbished computer monitors - Selection criteria for the monitor is appropriate size to suit your application and good image quality. Because of mass production, prices of large monitors are falling. Hence it is better to go for large size monitor, if you are ready to spend some extra money. This will give you good advantage.
Dot pitch - The first important parameter is Dot pitch. What is dot pitch? Let us understand. Every object and character is made up of tiny dots. The distance between two dots is known as Dot pitch. Lower the distance better is the picture. Smaller the dot pitch the closer the dots are to each other and the image on the screen will be much sharper. Typically dot pitch of 0.28 or less is good.
Screen size - The monitor size is actually the size of the CRT measured diagonally form one corner to opposite corner. The actual viewable area will usually have smaller diagonal measurement.
Resolutions supported - Typical resolutions include 640 x 480, 1024 x 768, 1280 x 1024 and 1600 x 1200. Your video card must be able to support higher resolution. A monitor might support a resolution of 1600 x 1200 but highest resolution available depends on the highest resolution that the PC's video card is capable of producing.
Controls - Take a look at the controls on the computer monitor. Every monitor allows you to adjust the screen image, brightness and colors. Three types of controls are available-analog, digital and onscreen digital. Economy monitors offer analog controls in the form of knobs or dials on the monitor case. Digital controls are microprocessor-based and more precise. Adjustments to monitor settings made with digital controls are saved when you turn the power off. On-screen digital controls allow adjusting the monitor with just a few controls and menu options which appear on the screen.
Older monitors only have brightness and contrast controls. New monitors have additional controls that can control the size and position of the display. The latest computer monitors allow for the adjustment of advanced features, such as color convergence, vertical centering, vertical size, pincushion correction and many other adjustments. All CRT monitors have a degaussing circuit which zaps away color swirls produced by random (or the earth's) magnetic fields.
Features - Some monitors offer BNC connectors for red, green and blue signals, besides the standard 15-pin HDD VGA connector. Typically, monitors using these BNC connectors provide a sharper image. These BNC connectors will connect to a standard VGA connector via a special cable. This is usually included with the monitor, as no special video card is required.
Looks - Check out the focus and clarity of a monitor before you buy, as the clarity of monitors varies between brands. The only way to tell just how well a monitor will look is to physically see it you. So if possible, view the monitor while using the computer at several different resolutions. Remember, a good monitor will have a low Dot Pitch (.28 or smaller) and a high refresh rate (72 KHz or higher).
Anti-Glare Coating - Anti-glare coating on monitor screens makes images clearer. This anti-glare is obtained by spraying the monitor screen with silica coating, which reflects light at different angles to eliminate glare. Older monitors often do not have this coating. Anti-glare coating is must for your computer monitor.
Check point - Warranty: Warranty is major issue for the monitors. Most vendors provide carry in warranty to the nearest location. Some vendors provide on site warranty. On site warranty is preferable. Also warranty for more number of years is better. If there are six bad pixels in the LCD monitor, you need to replace it.
Be sure to check out the monitor's warranty as the warranty can vary from 1 to 3 years. Some manufactures offer on-site warranty, which means you don't have to ship your monitor or carry it into a service centre. With some monitors requiring two adults to lift them, an on-site warranty might prove handy. Also ask about where to get your monitor repaired when it is out of warranty. Safety and Energy Ratings Many monitors conform to a variety of power saving and low emission (electromagnetic) standards. A monitor conforming to MPR II guidelines states that it is within a set standard for electromagnetic energy emissions, which some studies have linked to health problems. Even stricter than MPR II guidelines are TCO guidelines. A FCC Class B rating states that the monitor conforms to a reduced amount of interference to nearby TV and radio reception. Consult the monitor's documentation for details.
The above points should be considered before selecting the refurbished computer monitors.
