ENGLISH 2 Thank you for purchasing the new MGD 203/MGD 403 high brightness monochrome monitor. We hope you will enjoy using it and we are confident that this quality product will meet your highest expectations.
3 INTRODUCTION ENGLISH The new MGD 203/MGD 403 is a very high brightness, high resolution digitally controlled autoscan monochrome monitor, based on the CyberScreen technology. ® This new monitor, specifically designed for medical applications, gives unique performances in term of brightness, resolution and spot size. Typical applications are X-ray display systems, Tele Radiology (TR), Picture Archiving and Communications Systems (PACS), Radiology Information Systems (R.I.S.) Cardiac Workstation, etc.
ENGLISH 4 The monitor will automatically sychronise within a wide range of scanning frequencies and determine the specific operating mode. Monitor behaviour (degauss & reset), image quality and screen geometry adjustments can be changed or selected via the hardware OSD by means of the front panel push-buttons. Your new monitor provides special features as: ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ ´ Very high contrast, high definition image.
5 MAIN FEATURES ENGLISH ADVANCED TECHNOLOGY The MGD 203/MGD 403 monitor includes the following advanced technologies: - CYBERSCREEN®: digital technology that allows the optimization of the picture quality all over the screen, corners included. MAGNETOMETER: the magnetic field inside your monitor may dramatically change whenever you tilt or swivel the monitor, or when you bring a magnetic object, e.g. an audio speaker, close to the monitor.
ENGLISH 6 AUTOSCAN This feature allows you to use your monitor with a wide range of video cards: the MGD 203/MGD 403 monitor will automatically synchronize at all horizontal frequencies in the range 30 - 95 KHz and vertical frequencies in the range 50-170 Hz, and will automatically discriminate the specific operating mode.
7 ENGLISH 1GUN / 3 GUNS BRIGHTNESS This function allows to select (via OSD menu) between Low Brigtness Mode (even better picture sharpness and reduced eye strain) and High Brightness Mode (full brightness). WARNING: This function is available only if “1-BNC” input is selected since it has no much sence with color video cards.
ENGLISH 8 REFERENCE SETTING Five different ‘pairs’ of brightness and contrast combinations can be defined, and stored in the monitor and selected via OSD menu. This feature is particularly attractive for OEMs using the monitor with multiple systems wich will save a lot of time in the factory and in the field as well (‘tailoring’ of the monitor adjustments on the specific system is no more needed). POWER MANAGEMENT The MGD 203/MGD 403 is ENERGY STAR compatible (requires “VESA DPMS” compliant signalling).
9 ENGLISH INSPECTION Before installation, please check your monitor for physical damages which may have occurred during transport, and also check that the package includes all the items below: ´ ´ ´ ´ Your new monitor (including pedestal) Power cord User manual Signal cable (optional) In case any items are missing or damaged, please contact your dealer or supplier.
