Frequently Asked Questions - L1935W DGM

What to do if the screen stays black but the indicator light is on?

Check that the signal cable is properly connected between the computer and the monitor. If the indicator is orange, the monitor is in power saving mode. Move the mouse or press a key. If the indicator is green but no image, perform an auto-adjustment by pressing the Auto button.

How to clean the monitor screen?

Turn off and unplug the monitor. Use a soft dry cloth slightly dampened with pure water or a glass cleaner without ammonia or alcohol. Never spray liquid directly on the screen. For the housing, use a slightly damp soft cloth.

The message 'Out of Range' is displayed, what to do?

This means the resolution or refresh rate exceeds the monitor's capabilities. Set your computer's resolution to 1440x900 at 60 Hz or a supported resolution. Consult the list of display modes in the manual.

How to activate the economy mode?

Press the Turbo button (▲) to switch between Image, Text, and Economy modes. Economy mode reduces backlight brightness to save energy and reduce eye strain.

My monitor does not detect the DVI signal, why?

Make sure your DVI cable is properly connected and the source is sending a signal. Use the OSD menu to select the Digital (DVI) input. If the problem persists, check that your graphics card supports the resolution and that the driver is up to date.

Can I use a VGA to DVI adapter?

Yes, but ensure the adapter is compatible. The monitor accepts analog signals via VGA and digital signals via DVI. Note that image quality may vary.

How to reset to factory settings?

Access the OSD menu by pressing the Menu button, navigate to the Reset option, and confirm. This will restore default settings.

Are there built-in speakers?

This model does not have built-in speakers. However, a stereo audio input is present. You can connect external speakers via the jack.

Is the monitor compatible with my Mac computer?

Yes, the monitor is PC and Mac compatible. Connect it via VGA or DVI (depending on available ports on your Mac) and set the appropriate resolution in System Preferences.

What to do if the image is blurry or distorted?

Perform an auto-adjustment by pressing the Auto button. If that does not resolve, manually adjust the Clock and Phase in the OSD menu under Image. Also check that the resolution is correct.

Power saver

Power control system, also called (Power Saver), is installed inside the LCD monitor.
If the monitor has not been used for a certain period of time, the system will turn the monitor to low voltage mode to save power. Slight movement of the mouse or any pressing key on the keyboard will return the original image.
The VGA card inside the computer configures Power Saver. You can use your PC to set the function.
The LCD monitor is compatible with EPA ENERGY STAR and NUTEK if used with a VESA DPMS computer.
To save power, turn off the LCD monitor power when not in use.

Plug & play

The new VESA Plug and Play function is used, eliminating the complicated and time-consuming installation process.
Use the Plug and Play system without encountering the usual installation problems. Your computer system can easily identify and automatically adjust the monitor.
The LCD monitor uses Display Data Channel (DDC) to send Extended Display Identification Data (EDID) to the computer system, so the computer system can auto adjust your monitor.

SAFETY

Note: Note the following safety precautions before using this monitor.

Electrical

Check the Voltage

Electrical Shock

This product should be operated from the type of power indicated on the marking label. If you are not sure of the type of power available, consult your dealer or local power company.
This product is equipped with a 3-wire grounding-type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-type plug.
To prevent electrical shock, do not insert any metal object into any opening in the LCD monitor casing.
Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage points or other risks. Refer all servicing to qualified service personnel.
If the power cord is damaged, do not use the LCD monitor. Do not place any object on the power cord, and place the power cord away from crowded areas.
While pulling the LCD monitor plug away from the socket on the wall, hold the plug not the power cord.
Do not expose the LCD monitor to rain and do not use in environments near water (such as in the kitchen, or near a swimming pool).
If the LCD monitor becomes wet, unplug the power cord immediately and contact a Service Center.
If the LCD monitor begins to perform abnormally, makes a noise, or emits smoke or odors, unplug it immediately and contact a service center.

Do not place items on top of the LCD monitor.
If the LCD monitor is not in use for a long time, unplug it and store it in the proper package. The original carton and packaging should be used if possible.
The openings in the LCD monitor casing are for ventilation. To prevent overheating, the openings should not be blocked or covered. Do not place the LCD monitor on a bed, sofa, blanket or other soft surfaces; as soft objects may block the vents in the LCD monitor.
If you place the LCD monitor on a bookshelf or other enclosed space, it is essential to leave an air-space of 4-inches (10cm) between the monitor and the enclosure.
