## Pen display results

**Setup 1: Huion Kamvas 13 + Samsung Galaxy Tab S8 Ultra**

The following setup worked for me.

* For this setup, I used a **Microsoft Surface Thunderbolt 4 Dock**
* Samsung S8 Ultra connected to the dock via the dock's attached Thunderbolt 3 cable
* Huion Kamvas top USB-C port connected with Huion 3-in-1 cable:
  * 3-in-1 cable red USB-A end (for power) connected to dock.
  * 3-in-1 cable black USB-A end (for data ) connected to dock.
  * 3-in-1 cable HDMI end not connected
* Huion Kamvas 13 lower USB-C port connected to the USB-C port on dock using a Thunderbolt 3 cable.

**Step 2: Samsung Galaxy S9 FE**

Samsung Galaxy S9 FE does not work with an external monitor. Because of this, I was unable to get it to work as a pen display.
