Computer monitors are mainly used in displaying texts and images that a computer generates. They normally have carbon or plastic frames, and viewing screens made of glass. Able to display images in different formats, resolution ranges from 1024 x 768 pixels for SVGA standard to 1600 x 1200 for higher-end models.
Computer monitors also come in different types to suit specific purposes.
CRT Computer Monitor: CRT or Cathode Ray Tube monitors give you crisp and vibrant images best for office and home use. Some models even come with specialized screens that help in eliminating screen glare.
Flat-screen Computer Monitor: Flat-screen monitors have large screens for viewing with resolutions higher than CRT monitors. They provide sharper, brighter images with high contrast ratios and are viewable from both vertical or horizontal angles.
LCD Computer Monitor: LCD monitors make use of electronic liquid crystals in assigning brightness and color to every pixel in an image. With at least a 450: 1 contrast ratio, they give you a wider range of colors with high-contrast displays.
TFT Computer Monitor: Thin Film Transistor or TFT monitors are similar to LCD monitors but are capable of generating pixels at a faster rate. They have a 500: 1 contrast ratio at the very least with a response time of around 8ms.
When buying computer monitors, there are a number of things you have to consider. Choose a monitor with resolutions that fit the applications you use most often. For ease in viewing, choose 17-inch monitors for office or home use. The 19-inch to 20-inch monitors are best for multimedia use for better image and photo viewing. For at-home use, monitors with 4: 3 aspect ratios would suffice. For office use however, aspect ratios of 15: 9 or even 16:10 is best for showing presentations.
