The step-by-step instructions in this guide are a general reference for installing the LED Display. If any details in this document are unclear, please contact your reseller for more information.
The LED Display can be installed on the Wall or on a Trolley.
You can mount the System Control Box in three different ways:
Ensure there is no direct airflow from air conditioning or heating vents blowing on the display.
Avoid installing the LED Display in places with high humidity.
Due to high power usage, always use power cords specifically designed for this product.
Wood may split if holes are not pre-drilled before installing the Wall Mount Brackets.
Ensure that the wall can safely support 162 kg and the power outlet supplies enough voltage (max: 1740W; normal: 609W).
Ensure the deviation of the wall surface is < 5 mm.
Wear protective gear, such as gloves and protective shoes, when handling the LED Display.
The Wall Mount Brackets come in with two different lengths (1199 mm and 1799 mm). You need two of each to mount the screen to the wall.
Ensure the wall area is an appropriate installation site.
Using the illustration as shown below as a guide, mark at least eight mounting holes and pre-drill them.
After mounting the first and second Upper Wall Mount Brackets to the wall, secure them with the Wall Mount Connector Plate using the six provided screws (PM6 x 10 mm).
After installing both Upper and Lower Wall Mount Brackets, the installation wall should look like:
Carefully lift Cabinet "C" onto the center of the Upper Wall Mount Brackets.
Ensure the Mounting Brackets sit securely on the Wall Mount Brackets as shown below.
Lift Cabinet "B" and install it on the left side of Cabinets "C". Install the two Cabinets together with the provided screws (M8 x 20 mm).
Check for unevenness of the Cabinets by rubbing the cross section between each Cabinet. If the cross section is not aligned, loosen the M8 screws slightly and tap the Cabinets until the cross section is flat.
Place the remaining Cabinets onto the Wall Mount Brackets. Install from the center to the right and left sides of the Wall Mount Brackets.
The left and right sides of the System Control Box are pre-installed with its Covers in the factory. The main system control board is on the right.
The safety wires are used to prevent the Right Cover from falling when accessing the System Control Box. Please ensure that the safety wires are never removed.
Use caution as the System Control Box panel is separated into two pieces with wires attached.
Carefully place the System Control Box on stable furniture that can safely support the System Control Box.
To open the Right Cover, slowly bring the supplied System Control Box Maintenance Tool near the surface of the Right Cover where the steel plate is located. Then, the Right Cover should detach from the System Control Box magnetically.
DO NOT try to remove or disconnect the safety wires. Please ensure that the safety wires are never removed.
Remove the Left Cover by gripping the top edge of the Cover and pulling it toward you. The Left Cover should simply lift away.
Secure the System Control Box panel with the Connector Plate using the provided screws (M3 x 6 mm).
Further secure the Connector Plate with the two provided screws (M3 x 5 mm).
Align the holes of the Cabinets with the System Control Box to attach.
Carefully route the Network and Power Cables through the holes in each Cabinet.
Install the System Control Box to the bottom of the Cabinets with the provided screws (M8 x 20 mm).
Connect the Power and Network Cables from the System Control Box to each Cabinet. Ensure to match the corresponding letters on the Cables to the Cabinets (A to A, B to B, C to C, and so on).
Connect the left system control board to the main system control board.
Connect the LED Display's left speaker to the Audio Out port of the system control board.
Ensure the AC unit of the System Control Box is properly connected.
DO NOT connect the System Control Box Power Cables at this time.
The meaning of wiring color may vary by country.
After connecting all Cables and wires, hold the top edge of the Right Cover toward the System Control Box to replace it. Once the Right Cover is replaced, it will be held in place magnetically.
Replace the Left Cover by aligning it properly with the System Control Box; then the Left Cover should attach magnetically.

Working with ViewSonic® Cast software (vCast, vCast Pro, and vCastSender), the vCast application will allow the display to receive laptop screens (Windows/Mac/Chrome) and mobile (iOS/Android) users’ screens, photos, videos, annotations, and camera(s) that are using the vCastSender application.
To adjust the Display Group Settings, select the Display Group icon 
located in the lower-right corner of the screen.
When the “Synchronized group screen all the time” function is toggled ON, it will display a synchronized group screen continuously. If it is toggled OFF, it will work on vCast mirroring only.
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 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 .
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.
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.
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.
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.
Apple AirPlay® is compatible with vCast for screen mirroring and content streaming under the same subnet environment only. An “AirPlay Password” will be generated on-screen for connection when using AirPlay to cast to a display.
Once connected, select Receive. The selected display screen will appear on the mobile device with an on-screen toolbar. Users can interact with the display with annotations, file sharing, etc.
