Connecting a GAOMON Pen Display When Your Computer Has No HDMI Port

Overview

Some computers—especially newer Macs and ultrabooks—no longer include HDMI or USB‑A ports. If your device lacks these ports, you can still connect your GAOMON pen display using the correct adapters or cables. This article explains what you need, what to avoid, and how to ensure a stable video signal.

1. Using an HDMI Adapter
   If your computer does not have an HDMI port, you can connect the GAOMON pen display using an HDMI adapter.
   
   Supported adapter types
   Choose an adapter that converts your computer's port → HDMI, such as:
   • USB‑C → HDMI
   • Thunderbolt → HDMI
   • DisplayPort → HDMI
   • VGA → HDMI
     Your computer may have ports like Thunderbolt, DisplayPort, or USB‑C. Identify your port type first to select the correct adapter.
2. Connecting the USB Cable
   If your computer does not have a USB‑A port, you can use a USB‑A adapter or hub to connect the GAOMON pen display's USB cable.
   NOTE: The USB connection handles data, not video.
3. Important Adapter Precautions
   • Avoid USB‑A to HDMI adapters
     USB‑A ports are not designed for video transmission.
   • Do not use USB hubs for video
     USB hubs do not support a display connection, which can cause signal failures when used for HDMI.
4. Recommended Setup
   For the most stable connection:
   • Use one‑to‑one adapters only (e.g., USB‑C → HDMI).
   • Connect the HDMI cable directly through the adapter.
   • Use a USB‑A adapter only for the USB data cable.
   • Avoid multi‑port hubs, except for those that support both data and video transmissions.
5. Summary
   Even without HDMI or USB‑A ports, your GAOMON pen display can be connected reliably using the correct adapters. The key is choosing direct, one‑to‑one video adapters and avoiding USB hubs or USB‑A video converters.
