Elgato Thunderbolt™ 3 Dock and dual display support

The number of displays you can use with Elgato Thunderbolt™ 3 Dock depends on the power of your computer’s graphics system, the type of displays you’re trying to use, and whether you're using a Mac or PC.

The following is a list of how you can use up to two monitors with Elgato Thunderbolt 3 Dock in various configurations.

Elgato Thunderbolt 3 Dock can use up to two 4K displays at the same time.

You have a few options when it comes to setup. The resolution and refresh rate available to your displays will be determined by whether you connect via Thunderbolt 3 (USB-C), DisplayPort, or using an HDMI adapter.

 
One DisplayPort Display


You can connect one DisplayPort display to either the Thunderbolt 3 (USB-C) port, or the DisplayPort port.

The DisplayPort connection will be up to 4096 x 2160 pixels.

To establish the connection, you can use:
  • A DisplayPort to DisplayPort cable, to the Thunderbolt 3 Dock's DisplayPort port, or
  • A USB-C to DisplayPort cable, to one of the Thunderbolt 3 Dock's USB-C ports.
 
Two DisplayPort Displays


You can connect two DisplayPort displays - one to the Thunderbolt 3 (USB-C) port, and one to the DisplayPort port, at the same time.

Both DisplayPort connections will be up to 4096 x 2160 pixels.

To establish the connections, you can use:
  • A DisplayPort to DisplayPort cable, to the Thunderbolt 3 Dock's DisplayPort port, and
  • A USB-C to DisplayPort cable, to one of the Thunderbolt 3 Dock's USB-C ports.
Alternatively, you can use a Thunderbolt to dual DisplayPort adapter, connected to a USB-C port

 
One HDMI Display (Via Adapter)


You can connect one HDMI display, using an HDMI adapter with the DisplayPort port.

The HDMI 1.4b connection (via a passive adapter) will be up to:

• 4096 x 2160 pixels at 24 Hz
• 3840 x 2160 pixels at 30 Hz
• 2560 x 1600 pixels at 60 Hz

However, if you use an active HDMI 2.0 adapter via either USB-C or DisplayPort, you can receive 4096 x 2160 pixels.

To establish the connections, you can use:

• A DisplayPort, to HDMI cable or adapter (HDMI 1.4b, up to 4K/30)
• An active DisplayPort, to HDMI 2.0 adapter (HDMI 2.0, up to 4K/60)
• A dual Thunderbolt to HDMI 1.4 adapter (on the USB-C port)
• A dual Thunderbolt to HDMI 2.0 adapter (on the USB-C port)

 
One DisplayPort Display and One HDMI Display (Via Adapter)


You can connect one display to the Thunderbolt 3 (USB-C) port, and then use a HDMI adapter with the DisplayPort port.

The DisplayPort connection will be up to 4096 x 2160 pixels.

• 4096 x 2160 pixels at 24 Hz
• 3840 x 2160 pixels at 30 Hz
• 2560 x 1600 pixels at 60 Hz

However, if you use an active HDMI 2.0 adapter via both USB-C and DisplayPort, you can receive 4096 x 2160 pixels for each display.

 
One Apple Thunderbolt Display and One HDMI Display (Via Adapter)


You can connect an Apple Thunderbolt Display to the Thunderbolt 3 (USB-C) port, and then use a HDMI adapter with the DisplayPort port.
