Using the Stand

Always place the device on a flat, stable surface. Failure to do so may cause the device to fall and damage the device and/or result in personal injury.

Setup Support Guide

Connecting to Power

The monitor can be powered in any of the following configurations:

Connecting External Devices

Your external device(s) can be connected in any of the following configurations:

Type C Connection

Connect a Type C cable from your external device to a Type C port on the monitor.

Mini HDMI Connection

Connect the mini HDMI cable from your external device to the mini HDMI port on the monitor.
Connect the USB Type A to Type C cable from your external device.

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 Delivery

Powering a Notebook or Mobile Phone

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

Power Delivery Output: DC 5V/9V/12V/15V/20V/Max 3A.

Power Supply Detection

This product will detect if the power supply device is an adapter, laptop or mobile phone.

If the power source is an adapter or notebook, the default brightness value will be 100.
If the power source is a mobile phone, the default brightness value 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 the mobile phone, do not adjust the brightness level higher as this may cause the display to flash or shut down.

Power Delivery - Further Information

Due to the design please note:

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 the power. It will NOT display the input signal.
Only when one of the Type C ports is recognized as a power adapter can the other one deliver two-way power.

If a laptop is connected first to the VA1655, then a mobile phone is connected second, the mobile phone’s battery will not be charged as neither Type C port recognizes the connection as being connected to a power adapter.

NOTE: If you want to display the mobile phone’s screen, you must unplug the Type C cable connected to the laptop.

If a mobile phone is connected first to the VA1655, then a laptop is connected second, the mobile phone’s battery will be charged as one of the Type C ports is recognized as being connected to a power adapter.

NOTE: If you want to display the laptop screen, you must unplug the Type C cable connected to the mobile phone.

Due to the VA1655’s design, do not connect two laptops or one laptop and a desktop computer at the same time. This can cause power distribution conflicts, resulting in flashing screens or the forced shutdown of the laptop(s).

NOTE:

If the laptop has a Type C port, please connect via Type C to the VA1655.
Do not connect the other Type C port of the VA1655 to another laptop or desktop computer via Type A and HDMI at the same time.
If the laptop only has HDMI and Type A ports, please connect via HDMI and Type A to Type C to the VA1655.
If the power output of the Type A port of the laptop is not greater than 10W, please use our power adapter to connect to the VA1655.
Do not connect the other Type C port of the VA1655 to another laptop or desktop computer at the same time.
