To keep your monitor looking like new at all times and to prolong the service life of your device, we recommend cleaning it regularly. Clean the casing and LCD surface as described below:
IMPORTANT: Never use thinner, benzene, alcohol (ethanol, methanol or isopropyl alcohol), scouring agents or other strong solvents as these may damage the casing and the LCD display.
Remove marks by wiping the casing with a soft cloth, which you have previously moistened with a mild cleaning agent. Never spray wax or cleaning agents directly on to the casing. (The manual contains exact details.)
Where necessary, the monitor surface may be cleaned using a soft cloth (for example a cotton cloth or glasses cloth). Stubborn marks can generally be removed by wetting the cloth with a bit of water to increase the cleaning strength.
We cannot make a direct recommendation. The output signal should be digital and should support the maximum resolution of the monitor.
The viewing angle relates to the angle, beneath which the contrast is better than 10:1. These are normally values of 160° to 178°. These values do not provide any information about what enormous differences in contrast may result within the viewing angle. The contrasts should not change significantly for users with a perpendicular view and a slightly side-on view. It must not make a difference whether the viewer is looking at the middle of the image or the edge of the image. How much the contrast stability varies with different LCD technologies is best checked using a measurement diagram or by a direct visual comparison. The more stable the contrast in the user's viewing frustum, the better the image rendering.
Contrast is the ratio of white to black and for monitors is normally stated as a dark room contrast from a controlled laboratory environment. Typical contrasts on printed paper are 6:1 for newspapers, 31:1 for laser printers, 49:1 for photo paper. For example, dark room contrasts cannot be achieved in the office because an extremely deep black cannot be achieved in normal ambient light – even with the screen turned off.
