Frequently Asked Questions - L1935WA DGM

How to adjust brightness and contrast?

Press the + or - buttons when the OSD menu is not displayed for quick adjustment of brightness and contrast. For precise adjustment, open the OSD menu by pressing the ≡ button, navigate to the Brightness and Contrast options and adjust with the + and - buttons.

What to do if the screen shows no image?

First check that the monitor is powered on (green LED). Make sure the power and signal cables are properly connected. If the LED is orange, the monitor is in power saving mode: move the mouse or press a key on the keyboard. If nothing is displayed, perform the STFC test: disconnect the signal cable, if the message 'No Signal Input' appears, the monitor is working.

How to use the power saving mode?

The monitor automatically switches to low power mode after a period of inactivity. To wake it up, move the mouse or press a key. You can also adjust the power saving settings via your computer's software compatible with VESA DPMS. For maximum savings, turn off the monitor when not in use.

What does the orange LED mean?

The orange LED indicates that the monitor is in power saving mode (standby). It lights up when the computer is in standby or the monitor receives no signal. To return to normal operation, move the mouse or press a key on the keyboard. If the LED remains orange, check the signal cable connection.

How to clean the screen?

First turn off the monitor and unplug it. Use a soft, dry cloth slightly dampened with pure water or a glass cleaner without ammonia or alcohol. Gently clean the screen without pressing. Never use harsh detergents like acetone, ethanol, or abrasive. For the casing, use the same damp cloth.

How to adjust the resolution?

The optimal native resolution is 1440x900 at 60 Hz. To change it, go to your operating system's display settings (Control Panel > Display > Screen Resolution). Select the recommended resolution. If the desired resolution does not appear, update your graphics drivers from Nvidia, Intel, or AMD websites.

What to do if the image is blurry?

Use the Auto adjustment function by pressing the ▼/Auto button when the OSD menu is not displayed. You can also manually adjust the Clock and Phase settings in the OSD menu (Image Menu) to fine-tune sharpness. Also check that the resolution and refresh rate are set correctly.

How to connect the monitor?

Connect the power cable to a wall outlet. Connect the video cable (VGA or DVI) between the monitor and your computer. If you are using built-in speakers (not installed on this model), connect the audio cable. First turn on the monitor, then the computer. The system will automatically detect the monitor thanks to the Plug & Play function.

What to do if the screen displays 'No Signal Input'?

This message appears when the video cable is disconnected or damaged. Check that the cable is properly connected to the back of the monitor and the computer. If the problem persists, try another cable or port. The message is normal during the STFC test: it confirms that the monitor is working.

How to reset to factory settings?

Press the ≡ button to open the OSD menu. Use the ▲ or ▼ buttons to select the Miscellaneous option (or Reset depending on version). Press + to enter, then select Reset and confirm. All settings will return to default values.

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 NÜTEK 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.

Electrical Shock

Unusual conditions

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.
