HOW TO OPTIMIZE THE DOS-MODE PLUG AND PLA Y

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. The DDC1 is a unidirectional data channel from the display to the host that continuously transmits EDID information. The DDC2B is a bidirectional data channel based on the I channel.

THIS MONITO WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS MONITOR OT OPERATE PROPERLY, THERE MUST BE A VIDEO INPUT SIGNAL.

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association (VESA) and/or the United States Environmental Protection Agency (EPA) and the Swedish Confederation Employees (NUTEK). This feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal present. When

C protocol. The host can request EDID information over the DDC2B

there is no video input signal this monitor, following a time-out period, will automatically switch to an OFF mode. This reduces the monitor’s internal power supply consumption. After the video input signal is restored, full power is restored and the display is automatically redrawn. The appearance is similar to a “Screen Saver” feature except the display is completely off. The display is restored by pressing a key on the keyboard, or clicking the mouse.

USING RIGHT POWER CORD

The accessory power cord for the Northern American region is the wallet plug with NEMA 5*15 style and is UL listed and CSA labeled. The voltage rating for the power cord shall be 125 volts AC.

TROUBLESHOOTING

Chapter 4

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 W i ndows shut down pattern. If you confirm the R.G.B. color is normal or not, please do it under 16-grey scalar pattern. This LCM is analog interface. So if the entire screen is an abnormal color that means the problem

happen in the analog circuit part, if only some scale appears abnormal color that stand the problem happen in the digital circui t part.

If you check the H/V position, please use the crosshatch pattern. This LCM support 20 timing modes, if the input timing mode is out of specification, the picture

appears abnormally.
