Frequently Asked Questions - L1933 DGM

How to clean the monitor screen?

Make sure the monitor is turned off and unplugged. Use a soft cloth slightly dampened with a screen cleaner. Never pour liquid directly on the screen and do not apply excessive pressure.

What to do if the screen remains black?

Check that the power cord is properly plugged in and the power LED is on. Make sure the VGA cable is connected properly. If the LED is blinking, the graphics card frequency may be out of range. Try restarting the computer or switching to a supported display mode.

How to adjust display settings?

Press the OSD Menu button to open the on-screen menu. Use the selection keys to navigate between options: Monitor Control (position, phase, clock), Graphic Control (contrast, brightness, colors), and Miscellaneous Control (language, volume). Confirm your settings with the function access button.

What resolutions are supported?

The monitor supports many VESA modes, including 640x480, 800x600, 1024x768, 1280x1024, as well as MAC and NEC modes. The maximum resolution is 1280x1024 at 75 Hz. Consult the manual for the full list of frequencies.

How to enable power saving mode?

The monitor is VESA DPMS compatible. When the computer goes into standby, the monitor detects the absence of a signal and enters low power mode. The power LED then blinks. To reactivate it, move the mouse or press a key on the keyboard.

What to do if liquid enters the screen?

Immediately unplug the monitor and contact a qualified technician. Do not attempt to repair it yourself. Exposure to moisture can cause permanent damage.

How to adjust the viewing angle?

Hold the monitor firmly by its frame and gently tilt it backward or forward. The angle can be adjusted from -3° to 20°. Avoid pushing beyond 20° to prevent the screen from falling. Be careful not to pinch your fingers.

Why is the power LED blinking?

The LED blinks when the monitor is in power saving mode (DPMS) or when it detects an incompatible frequency. If it blinks for no apparent reason, check the cables and the graphics card.

Can I use a different power cord?

Yes, but it must be identical to the provided cord: with grounding, type VCTF (Japan), SVT 18AWG (USA), or H05VV-F 3G 0.75mm² (Europe). Make sure it is certified according to local standards.

How to reset display settings?

In the OSD menu, go to Monitor Control or Graphic Control. Select the 'Reset' option and confirm. This will restore factory settings for position, phase, clock, contrast, brightness, and colors.

Power Management System

The LCD Monitor complies with the VESA DPMS (version 1.0p) power management proposal. The VESA DPMS proposal provides four phases of power saving modes by detecting the horizontal or vertical sync signal. When the LCD Monitor is in power saving mode or detects an incorrect timing, the Monitor screen will go blank and the power LED indicator will start to blink.

Troubleshooting

Troubleshooting Procedures

This LCD Monitor was pre-adjusted in the factory with standard VGA timing. Due to output timing differences among various VGA cards, you may initially experience an unstable or unclear display when a new display mode or new VGA card is selected.

This LCD Monitor Supports Multiple VGA Modes. Refer to Addendum for a listing of the factory preset modes supported by this LCD Monitor.

PROBLEM: Display is Unclear and Unstable

To stabilize and clarify your display, follow this procedure in this order:

1. It's best to adjust the display on a screen displaying of vertical lines. In Windows, load a wallpaper bitmap that has vertical lines in it. (or you can select the window shut down screen)
2. After you have the wallpaper loaded, open the OSD and select the "Clock" function. Press the top (or bottom) Adjustment Control button and continue pressing the button until you see vertical dark and light lines across the screen.
3. When you can see distinct light and dark vertical bands, stop pressing the Adjustment Control button. Now press the opposite (top or bottom) Adjustment Control button. The vertical dark and light bands will decrease in number. Keep pressing the button until the distinct bands disappear and you have a clear display.
4. Next, press the Function Control button to choose the "Phase" function. The Phase will adjust the horizontal display. Press the top (or bottom) Adjustment Control button and you will see horizontal dark and light lines appear. The number of lines increases as you press the button. Now press the bottom (or top)

PROBLEM: There is no LCD Display

If there is no display on the LCD, please perform the following steps:

1. Make sure that the power indicator on the LCD Monitor is lit, all connections are secure, and the system is running on the correct timing. Refer to the Addendum for information on timing.
2. Turn off the LCD Monitor and then turn it back on again. Press the upper Function Control button (refer to Chapter 2) once and then press either the upper or lower Adjustment Control button several times. If there is still no display, press the other Adjustment Control button several times.
3. If step 2 doesn't work, connect your PC system to another external CRT. If your PC System functions properly with a CRT Monitor but it does not function with the LCD Monitor, and the LCD Monitor's power LED is blinking, the output timing of the PC's VGA card may be out of the LCD's synchronous range. Please change to an alternate mode listed in Addendum or replace the VGA card and repeat steps 1 and 2.
4. If the PC doesn't function with the CRT monitor neither, check BIOS to see if there is a dual scan setting under the display mode item. Set the BIOS display mode to Dual Scan or CRT and try again. If there is still no display, then there may be a problem with your system. Contact technical support.
5. If the power LED is not lit, check to see if the AC power connector is securely connected. Verify that the AC adapter LED is lit. If the AC adapter LED is not lit, please contact your dealer for assistance.
