Useful Tips:

Ensure the clamp is fully extended and locked before mounting.

If one screen does not work, please check whether the following situations: If the expansion screen displays ”No Signal” after connecting the USB-C cable, it means that the C port of your laptop only supports the power supply, then you only need to connect the HDMI cable to the monitor extension to provide video signals for it. In this case, the screen needs to be connected with two cables.

If the screen shows a power saving mode reminder/flickering/black screen: It may be that your laptop’s power or voltage is not enough to support three screens working at the same time. Please connect an external 5V/2A power adapter to power the laptop.

When using, please open the bracket on the back of the screen to reduce the pressure on the laptop.

Before purchasing this product, please compare the port types of your laptop ports (and the docking station) to see if they match the connection options above. If they do not match, you can consult us for further solutions. If the number of ports is insufficient, you can choose to use a docking station to expand the number of ports.
