Listed below are factors to consider when comparing the specifications for choosing an LCD monitor:


SCREEN SIZE

Screen sizes are measured diagonally from the top right corner to the bottom left corner.
  • 15 to 17”: The most economical and usually offering all the features of larger models are ideal if for the casual web surfer or small business owner.
  • 19 inch and larger: For students, graphic designers and multi-taskers.


VIEWING ANGLES

The viewing angle is the angle of which you can view the monitor without the loss of brightness and colours. The viewing anle is directly relted to the contrast ratio (see below).
  • Standard viewing angle: Most users will be satisfied with the viewing angle on all the monitors.
  • Smaller viewing angle: Close to 90 degrees these monitors are designed for people requiring a higher privacy.
  • Larger viewing angle: Watching films, group viewings such as showing presentations.


BRIGHTNESS/LUMINANCE

The measurement of how much light a panel produces defined in candelas per meter squared (cd/m²), also known as nits.

  • 250 to 300 nits: The standard for LCD’s, suited to the casual web surfer and small business owner
  • 500 or more nits: This is recommended for viewers watching TV, movies or playing games


PIXEL PITCH

This is the distance between like-colored pixels in the display. The closer the pixels, the sharper the image.


RESPONSE TIME

This refers to the amount of time it takes for the crystals in the LCD monitor to turn on and off redrawing the image. It is measured in milliseconds, the lower the response time the less the blurring.

  • 8ms: For the casual web surfer or small business owner
  • 4ms or less: Gamers and movie viewers


CONTRAST RATIO

This is the difference between the darkest black and the brightest white. The higher the contrast ratio of the screen, the better the color representation is by the monitor. LCD monitors generally come in either an aspect ration of 16:9 (wide screen) or 15:9. Generally an aspect ratio of 16:9 is ideal for most users.


RESOLUTION

A LCD monitor resolution is the number of pixels that make up the actual screen viewing area., or the number of pixels that make up the actual screen viewing area.
  • 1280 x 1024 pixels: Standard resolution adequate for most users
  • 1680 x 1050 pixels: Ideal for gamers and movie viewers

Important note - When choosing an LCD check to see that it has a native resolution that matches your video card so that the images do not need to be scaled. If scaling needs to be done, images will not look as good.

Make sure the LCD has a native resolution that matches your video card. The native resolution of an LCD is an important because if the LCD has to scale the image to fit a different resolution, it won't look as good.


WARRANTY

Most LCD monitors are supplied with a standard 2-3 years warranty that covers all defects in manufacturing. However, many do not cover below 3 or 4 dead pixels.

What is a dead pixel? A pixel that is a bright or dark coloured spot that can only be seen when the background image on the screen is a different colour. This is caused by components failing within the display unit that can cause pixels to fail. It is recommended to select a monitor with a low counting or zero dead pixel warranty.
