[. . . ] CONNECTOR POWER MOUSE COMPUTER FUNCTION Low voltage power supply Universal mouse connector Combined connector for analog and digital RGB 13 USER GUIDE LCD PANEL 7 FEATURES The LCD panel has a variety of different features implemented. 7. 1. 1 INTELLIGENT SAFECOOL SYSTEM The fan operation is controlled by the overhead projector light (OHP). This safety feature ensures that the fan is always operating as long as the OHP is turned on. When the OHP is turned off, the fan automatically stops to minimize noise. The power supply must be attached to the panel for the fan to work properly. 7. 1. 2 SET-UP MEMORY The user controlled set-up, that usually is done when the panel is connected to a new computer, is automatically memorized for future use. The set-up information is stored in a non-volatile memory approximately 5 seconds after the last key is pressed. Several sources are predefined, while the remaining are available for customer set-up of sources. Custom sources are stored only if their sync pattern differs from any of the previous selections. Most settings are stored individually for each mode, including contrast, brightness, tune etc. 7. 1. 3 COLOR MAPPING A color-to-monochrome mapping scheme much like the one used in monochrome television sets is applied. This means that a color image of a human face appears natural in black and white. When using 64 shades, usually no information is lost, even in color intensive applications. 14 USER GUIDE LCD PANEL 7. 1. 4 SVGA SVGA in 800 x 600 mode is compressed both horizontally and vertically to 640 x 480 resolution. This feature is convenient when displaying irregular images (like pictures, scanned images and coarse graphics). Regular images (patterns, text and fine line graphics) may look distorted due to the downsizing. In this case, we recommend setting up the computer in 640x480 mode for a precise image. 7. 1. 5 VGA TEXT VGA text is compressed correctly from 720 x 400 to 640 x 400 mode when the image is positioned correctly. The characters maintain their shape, as every ninth pixel is dropped horizontally between each character. 7. 1. 6 CONTRAST The contrast of an image is defined as the relation between dark and light colors. An image of high contrast is often regarded as ` hard' as compared , to the ` soft'feeling of a low contrast image. Low contrast is recommended for long term viewing, while high contrast is used to enhance details. It is however provided in case of adaptation to special graphics adapters that are close to those in the compatibility list. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures : Reorient the receiving antenna. Plug the equipment to a different outlet so that equipment and receiver are on different branch circuits. You may require the following booklet from the Federal Communications Commission (FCC) : "How to identify and resolve radio and TV interference problems", available from the U. S. [. . . ]
