Which USB-C port should a customer use? A Shopify product specification guide
Official manufacturer image of the model discussed in the guide. A customer looking for a monitor with a one-cable laptop connection needs two clear answers: which USB-C port carries the video signal, and how much power can the monitor deliver to the laptop?

When selecting a USB-C port for a laptop connection, two key factors to consider are which port transmits the video signal and the power delivery capabilities of the port. The Dell UltraSharp U2723QE monitor features three USB-C ports, all identical in appearance. According to the Dell manual and product specifications, customers should use the rear port labeled #5 for a one-cable laptop connection. Port #5 is capable of handling up to 90W of power delivery to the connected laptop.
The monitor's product page on Dell's website lists the maximum power delivery capabilities for each port. Port #5, which is used for video and power delivery, supports up to 90W. In contrast, the downstream USB-C port #15, located on the underside of the monitor, delivers up to 15W of power to connected accessories. This information is also reflected in the SCAN port illustration, where #15 is labeled as the USB-C downstream port.
To ensure compatibility and optimal performance, the included one-metre USB-C to USB-C cable should be connected to port #5 on the monitor and the laptop. Port #5 must support DisplayPort Alt Mode video output and USB Power Delivery input for a successful connection. With a compatible setup, the Dell U2723QE can display a resolution of up to 3840 x 2160 at 60Hz, while providing up to 90W of USB PD power from the monitor to the laptop.
The included USB-A to USB-C cable serves a different purpose and should be used for data transfer, rather than video or power delivery. It is important for customers to note the host requirements for USB-C functionality, as indicated in the Dell manual and charging table. The laptop's ability to negotiate power depends on its own specifications, with a 130W-rated laptop being unsupported by the monitor.
In addition to the power delivery capabilities, the Dell U2723QE supports USB-C data transfer at up to 10Gbps. The video and data modes available depend on the host device, the cable used, and the monitor's Display → USB-C Prioritization setting. The USB-C ports on the monitor also support various other functions, as detailed in the Dell manual, including Ethernet connectivity and audio output.
To assist customers in identifying the correct USB-C port, a combination of a visual diagram and a text legend should be provided. The diagram should be placed directly beneath the port illustration, with a clear legend alongside it. This allows customers to easily locate the relevant port, even when viewing the information on a smaller screen. The port labels, such as #5, #8, and #15, should be consistently used across both the diagram and the legend, as specified in the Dell manual and illustrated in SCAN's port diagram.
