HOW TO OPTIMIZE THE DOS-MODE PLUG AND PLAY Plug & Play DDC1/2B Feature This monitor is equipped with VESA DDC1/2B capabilities according to the VESA DDC STANDARD. It allows the monitor to inform the host system its identity and, depending on the level of DDC used, communicate additional information about its display capabilities. The communication channel is defined in two levels, DDC1 and DDC2B.
Chapter 3 MACHINE ASSEMBLY This chapter contains step-by-step procedures on how to assemble the monitor for maintenance and troubleshooting. NOTE: 1. The screws for the different components vary in size. During the disassembly process, collect the screws with the corresponding components to avoid mismatch when putting back the components. 2. The monitor surface is susceptible to scratching! Therefore, lay the monitor on a soft surface when mounting or removing the base. 3.
