Note: Select the devices to group first, then toggle the “Synchronized group screen all the time” function ON to avoid interruption.

Share a Screen to the Display Group (One to Many Casting)

After confirming the above settings, you can share your screen to the main display, then the grouped client devices will be synced up to your screen.

Moderator Mode

Moderator Mode allows the moderator to take control of the devices connected to the display. To enter Moderator Mode, select the Moderator Mode icon located in the lower-right corner of the screen.

When enabled, the moderator can view a list of all connected screens in the left floating window and can preview each participant’s screen and then select any of participant’s screen and cast to the display's main screen for presentation. The moderator can also control each participant’s screen, annotate on the display, and remove unwanted participants by selecting the close icon .

Broadcast

When enabled, the display's screen will be broadcasted to all of the participant’s connected screens simultaneously. The participants can only view the presentation contents until the moderator disables the Broadcast function.

Multiple Screen Sharing

By default, vCast is set to allow multiple screen sharing, but can also be set to single screen sharing. To do this, the moderator can select the Multiple Screen Sharing icon to switch to single screen sharing.

Preview Screen

By default, vCast is set to let the moderator preview the participant’s screen contents prior to sharing to the display. Selecting the Preview Screen icon, the Moderator can switch to see the participant’s name only.

Touch

By default, participants can use touch for collaboration after connecting. The moderator can enable/disable the touch function of a participant by selecting the Touch icon in their window.

Note:

• Moderator Mode is supported on all vCastSender and AirPlay devices, but mobile devices are limited to a "preview" function. Additionally, mobile Android devices cannot cast sound out.
• When you cast your Windows/Mac/Chrome screen to a display, the selected full screen unit will not be broadcasted back to your device to avoid repetitive screen casting.
• The active presenter can touch each of the participant's screens to remotely control casting devices.
• The number of multi-screen presenters on-screen depends on your Windows CPU processor performance and router specifications.

Using the Direct View LED Display Safely

Please read the following Safety Precautions before you start using the device.

Keep this user guide in a safe place for later reference. Read all warnings and follow all instructions. Ensure there is no direct airflow from air conditioning blowing on the display. 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 or other sources of sustained heat. Do not install near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that may increase the temperature of the device to dangerous levels. When moving the device, be careful not to drop or bump the device on anything. Do not place the device on an uneven or unstable surface. The device may fall over resulting in an injury or a malfunction. Do not place any heavy objects on the device or connection cables. If smoke, an abnormal noise, or a strange odor is present, immediately turn the device off and call your dealer or ViewSonic®. It is dangerous to continue using the device. Do not attempt to circumvent the safety provisions of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade and the third prong are provided for your safety. If the plug does not fit into your outlet, obtain an adapter and do not attempt to force the plug into the outlet. When connecting to a power outlet, DO NOT remove the grounding prong. Please ensure grounding prongs are NEVER REMOVED.

Protect the power cord from being treaded upon or pinched, particularly at the plug, and at the point where it emerges from the equipment. Ensure that the power outlet is located near the equipment so that it is easily accessible. Only use attachments/accessories specified by the manufacturer. When a cart is used, use with caution when moving the cart/equipment combination to avoid injury from tipping over. Disconnect the power plug from the AC outlet if the device is not being used for a long period of time. Place the device in a well-ventilated area. Do not cover the surface of the display with any material. Do not block the air circulation around the display. Keep flammable materials away from the display. Refer all servicing to qualified service personnel. Service will be required when the unit has been damaged in any way, such as: if the power supply cord or plug is damaged; if liquid is spilled onto or objects fall in the unit; if the unit is exposed to moisture; if the unit does not operate normally or has been dropped. Do not assemble the display by yourself. This panel is an advanced product that contains millions of pixels. You may occasionally see pixel spots when viewing the screen. Since these deactivated pixels are not a defect, the performance and reliability of the product is not affected.

Maintaining the LED Display

General Precautions

• The LED lights used in the modules are susceptible to ESD (Electrostatic discharge). To prevent damage to the LED lights, do not touch them with bare hands or with conductive materials when handling.
• It is recommended to regularly inspect all installed components.
• Do not bring objects close to the ventilation holes of the display. Burns or personal injuries may occur if any body parts are brought too close.
• Be sure to power off and disconnect all cables before moving the display. Moving the display with its cables attached may damage the cables and thus cause fire or electric shock.
• Power off and disconnect the power plug from the wall outlet as a safety precaution before performing any type of cleaning or maintenance.

Initial Operation

• If a new screen has been stowed for less than three (3) months, it can be used at normal brightness during its first use.
• If a new screen has been stowed for more than three (3) months, the brightness should be set at 30% for its first use and allowed to operate for two (2) hours continuously. After two (2) hours of use, power off for 30 minutes. The new screen is now ready for normal brightness usage.

Front Panel Cleaning Instructions

• Use cool, compressed air to remove dust when the power is off. If the dust cannot be removed, the LED module should be replaced.
• Do not scratch and do not put pressure on the panel surface with fingers or any abrasive object.
• Do not use volatile substances such as sprays, solvents, or thinners.

Cabinet Cleaning Instructions

• Do not allow water or detergent to come into contact with the surface of the display. If water or moisture gets inside the unit, a system malfunction or electrical shock may occur.
• Do not scratch and do not put pressure on the cabinet with any abrasive objects of any kind.
• Do not use volatile substances such as sprays, solvents, or thinners on the cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any extended periods of time.

Regular Use

• It is recommended to turn on the display at least once a month for more than eight (8) hours. During a wet and rainy season, it is recommended to turn on the display at least once a week.
• Avoid using full white, full red, full blue, or full green content for an extended period to avoid excessive power usage thus affecting the LED lifespan.
