What should you check before buying?
Start with the tablet’s connection diagram, then match its video, USB data and power needs to the laptop and dock. If you also want extra monitors or laptop charging, check those as part of the complete setup.
| Concern | What to check | Who this matters to |
| Host-port video compatibility |
For a native-video dock, check the exact laptop port for DisplayPort Alternate Mode, Thunderbolt or applicable USB4 video support, then match the dock’s host requirement. |
If I use a USB-C pen display, I need to know that the laptop can send it a picture through the dock, not merely that the plug fits. Around 36% of consumers put host-port video compatibility first. |
| Separate video, data and power |
Use the exact tablet’s connection diagram to count its video socket, USB data connection and any separate power connection. |
With a split-cable pen display, I need every lead connected at once or I could lose the picture or pen input. Separate connection and power planning is the primary concern for around 29% of consumers. |
| Workspace connections and charging |
Compare the needed peripheral ports, display modes and laptop charging arrangement with the dock’s specifications and host requirements. |
If the tablet shares my desk with other peripherals or monitors, I want the dock to accommodate the whole arrangement without overlooking laptop charging. Around 21% of consumers prioritise that workspace expansion. |
| Basic USB pen-tablet connection |
Confirm the tablet’s USB connector and laptop software requirements; check Bluetooth only if the exact variant offers it. |
When my tablet has no screen, I mainly need a way to connect it as a data peripheral rather than another video output. That straightforward connection comes first for around 14% of consumers. |

Targus USB-C Universal Dual HDMI 4K Docking Station with 100W Power Delivery Pass-Thru
Consider this for a tablet whose documented setup uses HDMI video and separate USB data, provided the laptop and dock support the required video path.
The product name specifies dual HDMI, 4K and 100W Power Delivery pass-through. Confirm the USB data connection, the applicable display mode and the dock’s power-adapter requirements for your complete setup; laptop Power Delivery is not a tablet-power specification.

Frequently asked questions
Will any USB-C dock connect my graphics tablet?
No: the connection depends on whether the tablet has a screen and on the exact laptop port. A USB pen tablet needs a suitable data connection, while a pen display may also require native video, a separate USB lead and its own power connection; follow the tablet maker’s diagram.
Why does my pen display show a picture but not respond to the pen?
On Wacom pen-display HDMI arrangements that require separate USB data, HDMI carries the picture but does not provide the pen and touch connection. Check that the specified USB data lead is connected as shown in the guide for your model.
Will a dock’s laptop Power Delivery rating also power my tablet?
Not necessarily: a laptop Power Delivery rating does not establish the power available to a pen display. Check the tablet’s own power instructions and whether its required adapter or cable is part of your planned setup.
Does a DisplayLink dock need software?
Check the exact dock and operating system before buying. DisplayLink Support provides software installation guidance, and StarTech.com states that Windows and macOS drivers are required for its DK30CH2DPPDU model; a dock using native video is a different arrangement.
What should I check when buying a powered dock for Great Britain?
Check the exact product’s manufacturer and model information, supplied plug and power equipment, and marking information for the intended market. GOV.UK’s Great Britain guidance discusses UKCA and CE marking for England, Scotland and Wales; check the applicable arrangements separately for Northern Ireland.
