Safety Precautions

• Read these instructions thoroughly before using this device.
• Keep these instructions in a safe place.
• Observe all warnings and follow all instructions.
• Sit at least 45 cm (17.7 inches) from the screen.
• Ensure at least 10 cm (3.9 inches) of free space around the device for adequate ventilation.
• Handle the screen with care when moving it.
• Always use cabinets or stands, or installation methods recommended by the monitor set manufacturer.
• Always use furniture that can safely support the monitor.
• Ensure the monitor does not hang over the edge of the supporting furniture.
• Do not place the monitor where children are likely to be present.
• Always teach children about the dangers of climbing on furniture to reach the monitor or related equipment.
• Always manage cords and cables connected to your monitor so that no one can trip over them or pull them.
• Proceed with caution when removing the monitor's back cover. This monitor contains parts that are under high voltage.
• Do not use the device near water. To reduce the risk of fire or electric shock, do not expose the device to moisture.
• Avoid exposing the device to direct sunlight and other sources of sustained heat. Do not place the device near heat sources such as radiators, heating vents, or other appliances (including amplifiers) that may cause the device's temperature to rise to dangerous levels.
• Clean with a soft, dry cloth. Refer to "Maintenance" in this manual for more information if more thorough cleaning is required.
• Do not touch the screen. Skin oils are difficult to remove.
• Do not rub or apply pressure to the screen, as this may permanently damage it.
• Do not place the monitor on an unstable surface.
• Do not place the monitor on large furniture (e.g., a cabinet or bookcase) without anchoring both the furniture and the monitor to a suitable support.
• Do not place the monitor on a cloth or other materials that may be placed between the product and the supporting furniture.
• Place the screen in a well-ventilated area. Do not place anything on the screen that obstructs heat dissipation.
• Do not place heavy objects on the screen, video cable, or power cord.
• Do not place items that may entice children to climb, such as toys and remote controls, on top of the monitor or furniture where the product is placed.
• If smoke, abnormal sounds, or a strange odor occurs, immediately turn off the screen and contact the seller or ViewSonic. It is dangerous to continue using the screen.
• Never attempt to bypass the safety features of the polarized or grounded plug. A polarized plug has two blades, one wider than the other. A grounded plug has two pins and a ground clip. The wide blade of the polarized plug and the ground clip of the grounded plug are for your safety. If the plug does not fit your outlet, purchase an adapter. Never force the plug into the outlet.
• Ensure the distribution system installed in the building provides a circuit breaker specified at 120/240V, 20A.
• When connecting to an outlet, do NOT remove the ground clip. Ensure the ground clips are NEVER REMOVED.
• Position the power cord and plug so that they cannot be stepped on or pinched, and protect the point where the cable exits the device. Ensure the outlet is located close to the device for easy access.
• Use only attachments/accessories specified by the manufacturer.
• Use the device only with a cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the device. Be cautious when using a cart to move the device to prevent the device or cart from tipping over and potentially causing injury.
• Unplug the device from the outlet if you will not be using it for an extended period.
• Leave maintenance and repairs to a qualified technician. Repair is required when the device has been damaged in any way, such as: if the power cord or plug is damaged, if liquid is spilled or objects have fallen onto the device, if the device has been exposed to rain or moisture, or if the device is not operating normally or has been dropped.
• If using earphones/headphones, adjust the volume to a suitable level to prevent hearing damage.
• Stability hazard: The screen may fall and cause serious physical injury or even death. To prevent injury, this screen must be securely attached to the floor/wall in accordance with installation guidelines.
• If the existing monitor is to be stored and moved, the same considerations as above should be applied.

  NOTE: The USB Type A to Type C connection will also supply power to the monitor from the notebook. The power output must be greater than 10W.

Power Supply

Powering a Notebook or Mobile Phone

If the supplied power adapter is connected to the monitor, the monitor can then charge a connected notebook or mobile phone.

NOTE: Output power supply: DC 5V/9V/12V/15V/20V/Max 3A.

[Diagram showing the power adapter connected to a wall outlet, then to the monitor, and then USB Type C cables connecting to a laptop and a smartphone.]

Power Detection

This product will detect whether the power source is an adapter, laptop, or mobile phone.

• If the power source is an adapter or notebook, the default brightness level will be 100.
• If the power source is a mobile phone, the default brightness level will be 15.
• When using a mobile phone to power the monitor, the default brightness level will be 15.

NOTE: Due to the limited power output of a mobile phone, do not set the brightness level higher, as the screen may flicker or turn off.

Power Supply - More Information

Consider the following due to the monitor's design:

• The first connected device will be the main input signal.
• When a Type C port recognizes an external device as a power adapter, it will only distribute power. It will NOT display an input signal.
• Only when one of the Type C ports is recognized as a power adapter can the other supply power in both directions.

If a laptop is connected first to the monitor, and a mobile phone is connected second, the mobile phone's battery will not be charged because no Type C port recognizes the connection as a power adapter.

NOTE: To display the mobile phone's screen, disconnect the Type C cable connected to the laptop.

If a mobile phone is connected first to the monitor, and a laptop is connected second, the mobile phone's battery will be charged because one of the Type C ports recognizes the connection as a power adapter.

NOTE: To display the laptop's screen, disconnect the Type C cable connected to the mobile phone.

Due to the monitor's design, do not connect two laptops or one laptop and one desktop computer simultaneously. This can cause conflicts in power distribution, leading to flickering screens or forced shutdown of the laptop(s).

NOTE:

• If the laptop has a Type C port, connect via Type C to the monitor.
• Do not connect the monitor's other Type C port to another laptop or desktop computer via Type A and HDMI simultaneously.
• If the laptop only has HDMI and Type A ports, connect via HDMI and Type A to Type C to the monitor.
• If the power output of the laptop's Type A port is not greater than 10W, use our power adapter for connecting to the monitor.
• Do not connect the monitor's other Type C port to another laptop or desktop computer simultaneously.

Using the Monitor

Powering the Device On/Off

1. Connect to a power source in one of the available configurations.
2. Press the Power button to turn on the monitor.
3. To turn off the monitor, press the Power button again.

[Diagram showing the rear of the monitor with the power button highlighted.]

NOTE: The monitor will still consume some power as long as the power cord is connected to the outlet. If the monitor is not used for a long time, unplug the power cord from the outlet.

Maintenance

General Precautions

• Ensure the monitor is turned off and the power cord is unplugged from the outlet.

Cleaning the Housing

• Use a soft, dry cloth.
• If the housing is still not clean, you can apply a small amount of non-abrasive cleaning product (not ammonia or alcohol-based) to a clean, soft, lint-free cloth and wipe the surface clean.

Disclaimer

• ViewSonic® recommends against using ammonia or alcohol-based cleaning products for the screen or housing. We have been informed that some chemical cleaning products may damage the monitor's screen and/or housing.
