l l Check that the cable is attached correctly to the computer. l Press any key on the keyboard to wake-up the computer from power saving mode. 49. Why is there no picture on my monitor even though the power LED is green? Verify the Contrast and Brightness setting of the monitor. First press and hold the 5 button to increase Contrast and then press and hold the 4 button to increase Brightness. These buttons are located on the front of your monitor. l l Press both the 5 button and the OK button at the same time to switch input A|B. l Try and repeat step 48 above. 50. Why does the picture disappear after I press the on/off button quickly? This is a unique Philips feature designed to preserve the life of your monitor. Please allow 5 seconds between powering off and on your monitor, your picture will then be restored. Glossary A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A Autoscan A microprocessor-based feature of Philips Brilliance monitors is able to detect automatically horizontal and vertical frequencies of input signals with those of the installed video card. An autoscan monitor can thus operate with a wide range of video cards. MultiSync, a registered trademark of NEC, provides a similar function. RETURN TO TOP OF THE PAGE B Balanced pincushion See Geometric distortion BNC connection A special construction of connector used in some monitors with higher horizontal scanning frequency. The BNC connection can provide the optimum shielding and matching characteristic impedance of video signal path to ensure the best video performance. RETURN TO TOP OF THE PAGE C CE Mark CE mark is displayed on products per EMC and LV ( low Voltage Device ) directives in compliance with European Community safety, EMI and EMS requirements and is compulsory on products for sale in the European Community. Color temperature A way of describing the color of a radiating source in terms of the temperature (in degrees Kelvin) of a black body radiating with the same dominant frequency as the source. Most Philips monitors offer the possibility of setting the color temperature to any desired value. Contrast The ratio between the brightness of the brightest and darkest parts of a picture. The darkest part of a picture is set by the brightness of the unexcited phosphor, which is governed by the degree with which ambient light is reflected. Contrast is therefore reduced in conditions of high ambient light levels. Black Matrix tubes reflect less ambient light so exhibit higher contrast than other tubes. Convergence error Bean misalignment causing one or more of the three beams passing through the wrong aperture in the shadow mask and striking a phosphor dot in the wrong triad. Convergence error is expressed in mm often at three well-defined points on the screen, designated A, B and C (see figure ). Also known as misconvergence. Points where convergence error is specified. Convergence-error correction A method of correcting for convergence error to insure that all three beams land simultaneously in the same triad. This is usually accomplished by means of special convergence-error correction coils in the deflection yoke. CRT Cathode-ray tube - the general term for all tubes in which one or more electron beams emitted by a cathode are periodically scanned across a phosphor screen by means of deflection circuitry. A special form of the cathode-ray tube is the TV and monitor picture tube. CustoMax Philips proprietary monitor control software that allows users to control parameters (e.g., Size, Color, Geometry) using software running in Windows. CustoMax is compatible with existing VGA cards. See CrystalClear FAQ and USB Bay FAQ. RETURN TO TOP OF THE PAGE D DDC (Display Data Channel) DDC is a communication channel for displays and computers. The DDC feature allows the monitor controller to be automatically configured to make optimal use of the display without manual user interaction. DDC is implemented as part of the new Plug & Play approach introduced into the PC market to increase user friendliness. The three levels developed for Plug & play are: (1) DDC1, monitor send data to the PC; (2) DDC2B, PC can request information from monitor; and (3) DDC2Bi which is a two-way communication - monitor can be addressed and PC or graphics board can give commands to monitor. DDC 1/2B See DDC. DDC 2Bi See DDC. Degaussing The procedure of demagnetizing the shadow mask and associated metal parts of a picture tube at switch-on to minimize picture distortion. This is usually accomplished by means of a special degaussing coil through which a decaying alternating current is passed to generate an alternating magnetic field that gradually decays to demagnetize the tube. Some monitors offer a manual degaussing facility that can be activated at any time. Digital control Microprocessor-based digital control of picture parameters and video modes for complete control of picture settings and modes and instant recall of all settings at the push of a button.
