A large viewing area, stylish design, bright colours and sharp pictures - what more could today's discerning user ask for? The Multiscan 20se II offers high resolution and refresh rates while conforming to the latest ergonomic standards. For users requiring a 20� screen for multiple applications, graphics, photos and much more, the solid assurance of Sony Trinitron technology makes the Multiscan 20se II the monitor of choice. Unrivalled Trinitron Technology - 0.25 mm Pitch In 20" CRT The Multiscan 20se II is one of the few 20" monitors offering a 0.25 mm pitch - which means that colours remain as bright and pure as on smaller screens. Picture quality is uniform with Sony Trinitron technology - one hundred million Trinitron displays sold world-wide is ample proof of the Sony advantage. Digital Multiscan for Perfect Images Sony has created an intelligent monitor containing dedicated circuitry that adjusts image parameters automatically, eliminating geographic distortion. Digital Multiscan is the system within the 20se II that uses an internal CPU and ASIC to correct image distortions - such as pincushion balance. Responding to signals from the graphics card, the monitor determines the incoming video frequency and quickly performs all necessary adjustments. So distortion free images appear automatically, at any given resolution. Precision Control with On-Screen Display The Multiscan 20se II offers quick and precise control of a range of image parameters including size, centering and colour temperature thanks to a new on-screen display panel. These user-friendly controls make light work of picture adjustment, showing exact current settings and allowing digitally precise adjustments - at a glance. Windows 95 Users Need Plug and Play With the Multiscan 20se II, Windows 95 users can enjoy true plug and play functionality simply plug in the display to your PC and start to use it straight away. The 20se II offers Display Data Channel (DDC) compatibility, a new standard which allows the monitor to convey important information about itself to a DDC compatible graphics card. Automatic adjustments are then made based on signals from the monitor which make best use of the display - without any user input. Magnetic field compensation Because of the effects of the earth's magnetic field and the exceptionally fine 0.25 mm Trinitron pitch, special attention has been given to beam landing. Sony engineers have developed compensation circuitry to cancel the effects of beam mislanding for a uniform picture quality without distortion. NUTEK and Energy Star Power Management Sony remains committed to a policy of environmental and ergonomic safety. The Multiscan 20se II complies fully with the EPA's (USA Environmental Protection Agency) power management guidelines, and with even stricter guidelines laid down by NUTEK.
