Computer monitors display text and images generated by computers. They usually have plastic or carbon frames and glass viewing screens, which can display graphics in monochrome, gray-scale, and color. Their resolutions range from 1024 x 768 pixels, which is the SVGA standard, to as much as 1600 x 1200 in high-end models. They connect to the computer through VGA port or DVI, and can be placed on desktops, walls, or ceiling mounted.

Kinds of Computer Monitors:

CRT Computer Monitors

CRT (Cathode Ray Tube) computer monitors provide sharp, vibrant displays ideal for home and office use. They are larger and bulkier than the modern LCD or flat screen displays. Some models are made with special screens that eliminate screen glare. They have front buttons located at the bottom for adjusting screen brightness, contrast, position, size, shape, and color. Most models are compatible with Macintosh and PC operating systems.

Flat Screen Computer Monitors

Flat Screen Computer Monitors have larger viewing screens and higher resolutions than CRT monitors. They also have higher contrast ratios up to 1000:1, resulting in sharper images and brighter colors. They can be viewed from horizontal or vertical angles, but tend to distort colors from extreme angles. Some models mount onto walls or cabinets using arm mounts. They can accept standard VGA and digital input from DV cameras and other high-end devices. They usually have built-in speakers, security locks, and removable bases.

LCD Computer Monitors

LCD Computer Monitors use electronic liquid crystals to assign color and brightness to each pixel. They have a minimum contrast ratio of 450:1, providing a wider range of color and high-contrast displays. They can be viewed clearly from up to 170 degrees, making them clearly visible from across large rooms. They may also have built-in speakers, security locks, and removable bases.

TFT Computer Monitors

TFT Computer Monitors use active LCD displays that generate pixels at faster rate. They have a minimum contrast ratio of 500:1 and a response time of about 8 ms. They can be arm- or wall-mounted. They usually have built-in speakers, security locks, and removable bases.

Choosing The Best Monitor

Resolution: For heavy graphics applications, choose a computer monitor with a resolution of 1280×1024 pixels or higher.

Screen size: Choose a computer monitor with a 17-inch screen for home or office use. For professional and multimedia applications, choose a screen between 19 and 20 inches for better photo and image viewing.

Aspect ratio: For home use, get a computer monitor with an aspect ratio of 4:3. For office use, choose a wider unit with an aspect ratio of 15:9 or 16:10, which is ideal for displaying presentations.

Due to the affordability of LCD monitors these days (as well as lower energy consumption) this type of monitor would be your best bet. Just simply select the size and aspect ratio you would like. REMEMBER though that a 19″ wide-screen may look a lot different than a 19″ regular screen. When in doubt do to your nearest electronic store and take a look at the different sizes (then come home and buy it cheaper online!!)

Hope this helps.
