[. . . ] Safety and Troubleshooting Information Safety Precautions and Maintenance · Troubleshooting · Regulatory Information Safety precautions and maintenance WARNING: Use of controls, adjustments, or procedures other than those specified in this documentation may result in exposure to shock, electrical hazards, and/or mechanical hazards. Read and follow these instructions when connecting and using your computer monitor: l l l l l l Disconnect the monitor from the power supply if the monitor is not to be used for an extended period of time. Do not attempt to remove the back cover, as you will be exposed to a shock hazard. The back cover should only be removed by qualified service personnel. Do not place objects on top of the monitor cabinet, objects could fall into vents or cover them and prevent proper cooling of the monitor's electronic devices. [. . . ] The smaller the pixel size, the better the resolution of the monitor. Pixel size is determined by the size of the electron spot on the screen and not necessarily by the phosphor dot pitch (the size of the triad). Thus, a monitor with a large electron spot covering several triads can exhibit poor resolution even though its dot pitch is small. Pixel frequency The number of pixels that can be written in a video line per second. Pixel rate See pixel frequency Plug-and-Play See DDC. RETURN TO TOP OF THE PAGE R Raster The area on screen that electron beam can reach. Refresh rate See Vertical scanning frequency. Resolution The number of pixels that can be displayed on the screen. The resolution is specified as the number of pixels in a line multiplied by the number of horizontal lines. See also video graphic adapter. Rotation function The feature that allows users to adjust the whole screen rotating to be horizontal. Because of the magnetic field of earth, the screen of monitor will be tilt when the screen faces toward the different direction. RETURN TO TOP OF THE PAGE S Screen coatings Anti-Static coatings Due to bombardment by beam electrons, monitor screens become electrically charged when in use. Electrically charged screens surfaces can attract dust particles. An Anti-Static coating is a conductive coating deposited on the screen (or on a glass panel immediately in front of the screen) that conducts away the charge and prevents screen dust build-up. AGAS (Anti-Glare, Anti-Static) coating AGAS is a silica coating applied to the surface of the screen by a spinning and spraying process. It operates by diffusing reflected light to blur images of light sources on the screen. To provide anti-static properties, the coating is impregnated with small conductive particles. ARAS (Anti-Reflection, Anti-Static) coating ARAS is one of the most effective anti-reflection/anti-static screen treatments currently available. It is composed of a multi-layer structure of transparent dielectric material that suppresses specular reflections by broadband interference effects at the screen surface. Anti-static properties are provided by a single conductive layer within the multi-layer structure. With ARAS, the intensity of reflected light is reduced from around 4. 5% of the incident light (the reflectivity of uncoated screens) to less than 0. 5%. ARAS also has a major advantage over other screen treatments: It doesn't diffuse or scatter reflected light, so picture contrast and sharpness remain completely unimpaired. It's also easy to clean and tough enough to withstand commercially available cleaning agents. The ARAS coating reflects only about 0. 5% of the incident light. AGRAS (Anti-Glare anti-Reflection Anti-Static) coating. A combined anti-reflection, anti-glare, anti-static coating. Self-test function A monitor equipped with hardware or software to automatically detect cable connection status. Shape Deviation of a reproduced picture from its intended shape. The following types of distortion are most common: SOG (Synchronization On Green) A properly functioning color monitor requires five kinds of signals: horizontal sync pulse, vertical sync pulse, red color signal, green color signal and blue color signal. Signals from a PC are transmitted to a monitor using one of three methods: 1. Separate sync: Horizontal and Vertical sync signals transmitted separately 2. Composite sync: Horizontal and vertical sync pulses mixed into a single signal train.
