Before you begin
You can connect up to two 4K external displays directly, four 4K displays through a USB-C docking station or one 5K and above
display using the Thunderbolt 4 (USB-C) ports available on your XPS 13 9315 2-in-1.
Before you begin, ensure that you:
●Check the graphics options on your computer.
●Check the ports available on your external displays and decide on the modes of connections.
Check the graphics options on your computer
The number of external displays supported depends on the type of graphics processing unit (GPU) available on your computer.
NOTE: On computers with an Intel Iris XeGraphics GPU, you can connect up to two external displays or one 8K display.
The GPU supported by your computer is Intel Iris Xeintegrated graphics, and allows you to connect up to four 4K displays with a
USB-C docking station, or one 5K and above display.
Modes of connection
Depending on the connectors available on your external display, you can connect the displays to the Thunderbolt 4 (USB-C)
ports on your computer using:
●Thunderbolt 4 cables, adapters, or docking stations
●USB-C cables, adapters, or docking stations
NOTE: To experience the full resolution supported by your external displays, use appropriate cables. For example, use
DisplayPort or HDMI cables for 4K and above resolution.
NOTE: USB-C or Thunderbolt docking stations can be used to connect external displays to the computer using a single
USB-C cable, while charging the computer. For more information about the types of docking stations available from Dell,
search in the Knowledge Base Resource at www.dell.com/support.
NOTE: USB-C adapters can also be used to connect external displays to the computer, though these do not allow power
charging at the same time. For more information about the types of USB-C adapters available from Dell, search in the
Knowledge Base Resource at www.dell.com/support.
These are the Thunderbolt 4 (USB-C) ports available on your computer:
NOTE: When connecting a display indirectly using an adapter or docking station, it is recommended that you connect
the display to the docking station first, and then connect the docking station to the Thunderbolt 4 (USB-C) port on your

Troubleshooting
8K display not displaying correctly
Question
When I connect an 8K display to the computer using a Thunderbolt docking station, the display output is not correct from the
computer.
Cause
This may be because of a hardware limitation with the Thunderbolt docking station.
Workaround
Connect the 8K display directly to a Thunderbolt port on the computer (not using a docking station). After doing so, power the
display on and off again.
