4. Connect the USB devices. 1. Connect the USB cable between the PC and the monitor (via the upstream USB port). This upstream USB port transmits data between the PC and the USB devices connected to the monitor. Note that this step is not required if the video source is from the Thunderbolt™ 3 or USB-C™ inputs. 2. Connect USB devices via other USB ports (downstream) on the monitor. These downstream USB ports transmit data between the connected USB devices and the upstream port.
6. Connect the power cable to the monitor. Plug one end of the power cord into the socket labelled on the rear of the monitor. Do not connect the other end to a power outlet just yet. 7. Install the back cover. Align the back cover with the holes on the back of the monitor, and press both sides and the upper part of the cover against the holes to lock it into place as illustrated. Push the lower part of the back cover toward the monitor to secure it. 8. Organize the cables.
Turn on the computer too, and press the 5-way controller to select an input source. Follow the instructions in Getting the most from your BenQ monitor on page 34 to install the monitor software. Available input icons vary by model. To extend the service life of the product, we recommend that you use your computer's power management function.
How to detach the stand 1. Prepare the monitor and area. Turn off the monitor and the power before unplugging the power cable. Turn off the computer before unplugging the monitor signal cable. 2.
