Wall Mounting

Refer to the table below for the standard dimensions for wall mount kits.

For use only with a UL certified wall mount kit/bracket. To obtain a wall-mounting kit or height adjustment base, contact ViewSonic® or your local dealer.

Maximum Loading	Hole Pattern (W x H)	Interface Pad (W x H x D)	Pad Hole	Screw Specification & Quantity
14 kg	200 x 100 mm	115 x 115 x 2.6 mm	Ø 5 mm	M4 x 10 mm - 4 pieces

1. Turn off the device and disconnect all cables.
2. Place the device on a flat, stable surface with the screen facing down.
3. Remove the stand.



4. Attach the mounting bracket to the VESA mounting holes at the rear of the monitor. Then secure it with four (4) screws (M4 x 10 mm).



5. Follow the instructions that come with the wall mounting kit to mount the monitor onto the wall.

Using the Security Slot

To help prevent the device from being stolen, use a security slot locking device to secure the device to a fixed object.

Additionally, fastening the monitor to a wall or fixed object using a security cable can help support the weight of the monitor in order to prevent the monitor from falling over.

Below is an example of setting up a security slot locking device on a table.

Connecting to Power

1. Connect the power cord to the AC IN jack at the rear of the device.
2. Connect the power cord plug to a power outlet.

Connecting External Devices

Note: To connect the monitor to an external device (PC, laptop…etc.), please use one of the included video cables for your application and connect it to both terminals.

DisplayPort MST Daisy Chain Connection

With DisplayPort Multi-Stream Transport (MST) support, you can daisy chain connect up to four (4) monitors.

1. Connect one end of a DisplayPort cable to the DisplayPort Out port of your computer. Then connect the other end of the cable to the DisplayPort In port of the monitor.
2. Use another DisplayPort cable to connect to the DisplayPort Out port of the first monitor. Then connect the other end of the cable to the DisplayPort In port of the second monitor.
3. Repeat Step 2 as needed with up to four (4) monitors.

NOTE: Your graphics card compatibility and monitor resolution will determine the number of monitors.

NOTE:

• DisplayPort 1.2 MST must be turned on in the Setup Menu in the OSD Menu to enable daisy chaining.
• If the input source changes to HDMI, DisplayPort 1.2 MST will turn off automatically.

Tilt Angle Adjustment
