It allows the monitor to inform the host system of 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 I²C protocol. The host can request EDID information over the DDC2B channel. THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS MONITOR TO 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 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 THE 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. Supplied with units intended for connection to power outlet of personal computer: Please use a cord set consisting of a minimum No. 18 AWG, type SJT or SVT three conductors flexible cord. One end terminates with a grounding type attachment plug, rated 10A, 250V, CEE-22 male configuration. The other end terminates with a molded-on type connector body, rated 10A, 250V, having standard CEE-22 female configuration. Please note that power supply cord needs to use VDE 0602, 0625, 0821 approval power cord in European counties. 15 LM914 TECHNICAL SUPPORT (FAQ) Problem & Question Power LED is not on Possible Solution *Check if the Power Switch is in the ON position *Power Cord should be connected *Check if the PC system is Plug & Play compatible *Check if the Video Card is Plug & Play compatible *Check if the D-15 plug pin of Video Cable is bent *Make sure the AOC Monitor Drivers are installed (AOC Monitor Drivers are available at: www.aocmonitor.com) *Adjust the Contrast and Brightness Controls. *Move electrical devices that may cause electrical interference. *Computer Power Switch should be in the ON position. *Computer Video Card should be snugly seated in its slot *Make sure monitor's video cable is properly connected to the computer. *Inspect monitor's video cable and make sure none of the pins are bent. *Make sure computer is operational by hitting the CAPS LOCK key on the keyboard while observing the CAPS LOCK LED. The LED should either turn ON or OFF after hitting the CAPS LOCK key. *Inspect the monitor's video cable and make sure that none of the pins are bent. No Plug & Play Picture is fuzzy Picture bounces or a wave pattern is present in the picture The power LED is ON (orange) but there's no video or no picture. Missing one of the primary colors (RED, GREEN, or BLUE) 16 LM914 Screen image is not centered or sized properly. Picture has color defects (white does not look white) Horizontal or vertical disturbances on the screen *Adjust pixel frequency (CLOCK) and FOCUS or press hot-key (AUTO) *Adjust RGB color or select a pre-set color temperature from OSD. *Use win 95/98 shut-down mode Adjust CLOCK and FOCUS or perform hot- key (AUTO-key). CLOCK (pixel frequency) controls the number of pixels scanned by one horizontal sweep. If the frequency is not correct, the screen shows vertical stripes and the picture has not correct width. FOCUS adjusts the phase of the pixel clock signal. With a wrong phase adjustment the picture has horizontal disturbances in light picture. For FOCUS and CLOCK adjustment use "dot-pattern" or Win 95/98 shutdown mode pattern . 17 LM914 ERROR MESSAGE & POSSIBLE SOLUTION NO SIGNAL 1. 2.
