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.
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.
TROUBLESHOOTING 1. Common Acknowledge If you change the M/B, Please re-do “DDC” programmed &”Auto Color balance” If Replace “Power & Inverter board” only, please re-do “Auto color balance”. If you adjust clock and phase, please do it at condition of Windows shut down pattern. If you confirm the R.G.B.
