A drawing tablet connects to a PC with its required cable or adapter, and the manufacturer’s driver must be installed before the pen will track properly.
A tablet that lights up but never draws usually means one of three things is missing: the right cable, power (if it has a screen), or the driver.
Which Cable Does Your Tablet Need?
A plain pen tablet runs on USB data alone. A pen display has its own screen, so it needs video plus power — where setups go wrong.
Per Wacom’s setup pages, the Wacom One DTH134 and DTC121 pen displays support a single USB-C to C cable into a USB-C port that supports video output — Wacom’s energy-saving option A. The catch: a data-only USB-C port won’t push video, and cheap USB-C cables often skip it.
Older pen displays take the multi-cable route. The Wacom One DTC133 wants HDMI and USB-A to the PC, plus the power USB cable into the adapter and a wall outlet. The Cintiq Pro connects by USB-C after you plug in its power cable and AC adapter — and with no USB-C port, Wacom Link or Link Plus bridges USB-C from the tablet to DisplayPort plus USB-A on the computer.
Pen tablets are simpler. The Wacom Intuos Pro (2025) connects to a USB Type-C PC or Mac via a general USB Type-C conversion adapter or the separate ACK45006Z cable. The Wacom One pen tablet can run into a USB-A port with a USB-C to USB-A cable (not included).
Installing the Driver on Windows
Install the latest Wacom driver for Windows before drawing — an uninstalled tablet stays unrecognized no matter how good the cable is.
Download the current driver from Wacom’s support site, run the WacomTablet*.exe installer, accept the license agreement, and let it finish. Restart when asked — skipping the reboot is a common reason a tablet still doesn’t respond. After reboot, a Wacom Experience Program notice appears, then confirm detection in Wacom Center under Devices. If your model shows up, you’re ready to draw. If not, recheck the cable and port before reinstalling.
The same logic applies to any brand: cable first, driver second. If you’re still choosing between models, this roundup of tested drawing tablets for PC setups covers which connect cleanly over single-cable USB-C versus which demand the full HDMI and power rig.
| Tablet Model | Connection Setup | Power Needed |
|---|---|---|
| Wacom One DTH134 / DTC121 | USB-C to C into a video-capable USB-C port | No, single-cable |
| Wacom One DTC133 | HDMI + USB-A to PC, display connector to tablet | Yes, AC adapter |
| Cintiq Pro (USB-C PC) | USB-C direct, after power is connected | Yes, AC adapter |
| Cintiq Pro (no USB-C PC) | Wacom Link / Link Plus: DisplayPort + USB-A | Yes, AC adapter |
| Wacom Intuos Pro (2025) | USB Type-C with conversion adapter or ACK45006Z cable | No |
| Wacom One pen tablet | USB-C to USB-A cable (not included) | No |
| One by Wacom pen tablet | USB cable, works with Chromebook too | No |
Pairing Over Bluetooth
Bluetooth works on supported Wacom devices, but only after the tablet is charged and disconnected from USB. Hold the Power/Bluetooth button until the blue LED blinks slowly, then pair from your computer’s Bluetooth settings. The driver must be installed on the second computer before repeating the pairing there. A pen display still needs its cables, since Bluetooth cannot carry video.
Two final notes: power adapters vary by region, so included hardware may differ outside the U.S. And a Wacom One is not stand-alone — a PC connection is required. Wacom’s support article on connecting the Wacom One DTC133 spells out the full HDMI and USB-A sequence.
FAQs
Why does my pen display show no image after connecting?
The cable or port likely doesn’t carry video. Single-cable USB-C pen displays need a video-capable port, and many cables skip it. Try a different USB-C port, a known video-capable cable, or the HDMI and USB-A setup your model lists.
Do I need to install the driver before drawing?
Yes. Without the manufacturer’s driver, Windows may see the device but the pen won’t track correctly and pressure sensitivity won’t work. Install the latest driver, restart, then confirm the tablet appears in Wacom Center under Devices.
Can I use a drawing tablet wirelessly with my PC?
Some Wacom models support Bluetooth. Charge the tablet, unplug USB, hold the Power/Bluetooth button until the blue LED blinks slowly, then pair from your computer’s Bluetooth settings. Pen displays still need cables, since Bluetooth doesn’t carry video.
