When selecting an item to be adjusted, moving the adjustment control past the last icon on the screen (either left or right) will take you to the other Main Menu page. Listed below are the icons, icon names and icon descriptions of the items that are shown on the Main Menu 1 OSD : Horizontal Position (To move picture image left and right) Horizontal Size (To adjust image width) Vertical Position (To move image up and down) Vertical Size (To adjust image height) Listed below are the icons, icon names and icon descriptions of the items that are shown on the Main Menu 2 OSD : Zoom (To adjust H and V image size simultaneously) Side Pincushion (To correct the bowing in and bowing out of the image) Trapezoid (To correct geometric distortion) Rotation (To adjust tilt) Listed below are the icons, icon names and icon descriptions of the items that are shown on the Main Menu 3 OSD : Degauss (This button is used to demagnetize the picture to give a more accurate image and color) Recall (To recall the factory preset mode) Help (To inform users of preset and user mode data) Listed below are the icons, icon names and icon descriptions of the items that are shown on the Main Menu 4 OSD : Color Code (To select color temperature, 9300 K/7200 K/user) RGB Adjust (To adjust individual RGB color at user color code) 9 Power Management System This monitor incorporates new circuitry for lowering energy usage during idle time, following the Display Power Management Signalling (DPMS) guide-lines of the Video Electronics Standards Association (VESA), and is certified as exceeding the EPA's Energy Star program for reduced power usage. For the power saving feature to operate, the monitor must be used with either a PC having power saving circuitry or a PC running screen blanking software. The monitor has three power-saving states, and the power saving operation is indicated by the power indicator on the front panel. When the power indicator is green, operation is normal. When the power indicator is orange, the monitor is in a power saving mode. If the power indicator is dark or blinks orange, press the power button to turn on the monitor. If the power indicator is orange and you wish to use the PC again, move your mouse pointer or touch a keyboard button. When the monitor is not in use, save energy by turning it off. Image Adjustment This monitor has a microprocessor-based On Screen Display (OSD) control system for adjusting the following items: Contrast, Brightness, Horizontal width, horizontal position, vertical height and position, side pincushion and trapezoid, zoom, Rotation, and color levels. When you make adjustments to any of the above items, the microprocessor will automatically memorize the adjustments you made. Your settings will be maintained even if you turn off the monitor and turn it on again. NOTE: The only time you may need to adjust the image settings again is in the event you change video modes (for example, you may go from a 640x480 video mode in DOS to an 800x600 video mode for windows). In this event, you may need to adjust the image controls again to meet the image display you desire. Now, the microprocessor will memorize the new image settings you made in the 800x600 video mode, having already stored your 640x480 image settings. From now on, when you switch between a 640x480 mode and a 800x600 mode, the monitor will recall each of the specific image settings you made in each of these modes. More on image memory modes in the video memory modes section. 10 Video Memory Modes This multi-synchronous auto-scanning monitor can automatically detect and display several video modes falling within the monitor's scanning range of 30-65KHz Horizontal and 50-110Hz Vertical. In the PC area, this relates to a maximum flicker free usable resolution of 1024x768 at a non-interlaced refresh rate of 75Hz Vertical. For convenience, the monitor has a 35 mode memory, of which 7 modes come from the factory preset to popular video modes as described below. Mode Display Mode 1 2 3 4 5 6 7 VGA720 x 400 VGA640 x 480 VESA640 x 480 SVGA/VESA75,800 x 600 1024 x 768 1024 x 768 1280 x 1024 Horizontal Frequency 31.47 KHz 31.47 KHz 37.50 KHz 46.88KHz 56.47 KHz 60.02 KHz 63.98 KHz Polarity Vertical Frequency Horiz sync Verti sync 70 Hz 60 Hz 75 Hz 75 Hz 70 Hz 75 Hz 60 Hz + + + + + + + Comments Factory fixed, but may be updated by user's setting. Modes15-35 are empty and can accept new video data. If the monitor detects one of the above signals from your computer's video card, it will recall that mode and any stored image adjustments you may have made before. If the monitor detects a new video mode that had not been present before or is not one of the above listed factory presets, it will store a new mode automatically in one of the blank (empty) memory modes (in this example, mode 15). When you now adjust the OSD controls to your preference, these image settings will also be stored in mode 15. Whenever your video card or PC switches to the mode that the monitor recognizes as mode 15, your personal image settings will also be recalled. 11 A note about the video memory modes: There is a total of 35 video memory modes, generally more modes than you will use at any one time. Of these 35 modes, 7 are permanent, factory fixed modes that cannot be changed, and another 7 are set at the factory, but may be overwritten to make more room. The remaining 21 modes are left blank (empty). If you use up the 21 blank modes and still have more new video modes, the monitor will store information in the other 7 soft preset modes for the new mode storage. If additional new modes are encountered, the monitor will delete the lowest memory mode and add the new mode. If you use a video card that has a number of resolutions and frequencies that do not correspond to any of the monitor video modes set at the factory, here's what will happen: 1) As the monitor encounters new video data, if you adjust the image control icons, the monitor will save the new information in the next available empty mode (mode 15 if this is the first new data encountered). 2) If you have used up modes 15-35 with 21 new video modes, and the monitor encounters another mode (36th mode), it will store the new data in mode 15 and the old data of mode 15 is deleted. In addition, If the monitor encounters 27th new video data, the old data of mode 16 is deleted and 27th data will replace the mode 16, with above method, when this monitor encounters new mode, it can update from mode 15 to mode 35 sequentially and continuously. mode Example:All 35 modes are filled with following data 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 m1 m2 m3 m4 m5 m6 m7 m8 m9 m10 m11 m12 m13 m14 m15 m16 data 33 m33 34 m34 35 m35 Factory fixed Soft presets When new data is encountered 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 m1 m2 m3 m4 m5 m6 m7 m8 m9 m10 m11 m12 m13 m14 m15 m16 33 m33 34 m34 35 m35 Factory fixed "m15"old mode 15 deleted Because the monitor is designed this way, you will always have the most common 28 video modes generated by your graphics card available with your own image settings recalled automatically. 12 Low Radiation Compliance (MPR II) This monitor meets one of the strictest guidelines available today for low radiation emissions, offering the user extra shielding and an antistatic screen coating. These guidelines, set forth by a government agency in Sweden, limit the amount of emission allowed in the Extremely Low Frequency (ELF) and Very Low Frequency (VLF) electromagnetic range. Self Diagnostics This monitor can sense when there is a possible problem present, and informs you of this condition by presenting you with a Self Diagnostics OSD. This OSD may pop up when it is On but no signal is detected. In this case the message CHECK S/CABLE will be high lighted, alerting you to check the signal cable connections. DDC (Display Data Channel) DDC is a communication channel over which the monitor automatically informs the host system(PC) about its capabilities.This monitor has three DDC functions; DDC1, DDC2B, DDC2AB. DDC1 and DDC2 carry out uni-directional communication between the PC and the monitor. Under these situations, the PC sends display data to the monitor but not commands to control the monitor servings. DDC2AB has the function of bi-directional communication. For example, the PC can fetch screen data from monitor and adjust the screen with the PC keyboard. NOTE: PC must support DDC functions to do this. HELP Menu The help menu, activated by selecting HELP Menu, gives you some operating information about the monitor: It is composed of the three sequential menus: The first menu shows the total number of the preset, user mode and current mode information, the second one shows the preset mode data stored, and third one shows the user mode data stored. Pressing the + key displays the next page. Pressing the - key displays the preceding page. 13 Troubleshooting Symptom: Self diagnostics message. Possible causes: The signal cable is not connected. Symptom: The power LED is illuminated orange or blinking orange. Possible causes: Display power management mode. These is no sync signal. The signal cable is not fastened securely. Check the computer power and graphics adapters configuration. The frequency of the sync input is outside the operating range of the monitor. HORZ:30KHz-65KHz VERT:50Hz-110Hz The signal cable is incorrectly configured or connected Refer to the page Signal connector pin assignment for reference. Symptom: The image on the SCREEN is not centered, too small, or not a rectangle shape. Possible Causes: Image adjustment not been done yet in the current operating mode. Use the SELECT and +/- buttons to set the image to your liking. Symptom:The monitor doesn't enter the power saving off mode (blinking orange led). Possible Causes:Computer video signal is not VESA DPMS standard. Either the PC or the video controller card is not using the VESA DPMS power management function. 14 Service 1.
