Q. Are monitors sensitive to magnetic fields?

A. Yes monitors can be sensitive to magnetic fields. This usually affects larger monitors more than smaller monitors. However, smaller monitors are not always immune to this sensitivity. Interference can come from electrical equipment including elevators. The simplest fix is to move the monitor away from the magnetic field. Monitors can be shielded from this sensitivity. Monitech uses an alloy product that can be placed around the picture tube to shield the monitor which works very effectively.

A. Degaussing or demagnetising is necessary for the release of any magnetic field build up of the electron beam alignment. All monitors degauss automatically at switch on, however, some larger monitors come with a degauss button that allows for manual override. It also means you don't have to send your monitor away for service.

Q. What is the difference between a multi-scanning monitor and a multi-frequency monitor?

A. A multi- scanning monitor will work with a wide range of horizontal and vertical frequencies while a multi- frequency monitor will only handle two or three preset scan combinations.

Q. How about refresh rates? How are they related to resolution?

A. Refresh rates refer to the speed a screen is redrawn or refreshed. The horizontal and vertical scan rates combine to provide the ability to produce a high resolution, flicker free image. As the monitor resolution increases, the information displayed on the screen increases as well. So it takes more time to refresh a screen and the refresh rate decreases. Find out the refresh rate of the monitor in various resolution, especially in the resolutions you plan to use. The standard for a flicker free display is a vertical rate of 75Hz or higher.

Q. How are monitor screens treated to reduce glare of reflection?

A. A non-glare screen is very important because it helps you read your screen better, making it easier to look at , even in a well Ðlit environment. Most proprietary types of anti-reflection, anti-glare coatings are variations of silica coating. This requires a good coating with the optimal amount of silica used for the screen treatment.

Q. How do I make adjustments to my monitor?

A. Many digital controls offer an on-screen menu that appears every time controls are activated. On-screen menus are visual, so users see their settings, making adjustment easier and more precise. They also help users match their screen colour to their printer output.
