How many displays can be used with Elgato Thunderbolt™ Dock? Last Updated: Jun 10, 2014 02:41PM PDT

The number of displays you can use with Elgato Thunderbolt™ 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 an exhaustive listing of how you can use up to two monitors with Elgato Thunderbolt™ Dock in various configurations.

To check to see if your Mac can support two monitors via Thunderbolt™, see Apple Technote http://support.apple.com/kb/ht5219#18

 
The Only Monitor is a DisplayPort Monitor


Mac:

You can use one DisplayPort monitor with the Elgato Thunderbolt™ Dock, by connecting it to the Thunderbolt™ port. 

This will work as long as no other monitor is connected to the HDMI port - if an HDMI monitor is connected, it will take precedence over the DisplayPort monitor, and the DisplayPort monitor will not work.


PC:

You can use one DisplayPort monitor with Elgato Thunderbolt™ Dock, by connecting it to the Thunderbolt™ port. 

This will work as long as no other monitor is connected to the HDMI port - if an HDMI monitor is connected, it will take precedence over the DisplayPort monitor, and the DisplayPort monitor will not work.

 
The Only Monitor is a HDMI Monitor


Mac:

You can use one HDMI monitor with Elgato Thunderbolt™ Dock.


PC:

You can use one HDMI monitor with Elgato Thunderbolt™ Dock.

 
The Only Monitor is a Apple Thunderbolt Display


Mac:

You can use one Apple Thunderbolt Display with Elgato Thunderbolt™ Dock. 


PC:

You can use one Apple Thunderbolt Display with Elgato Thunderbolt™ Dock.

 
One HDMI Monitor and One Apple Thunderbolt Display


Mac:

When using a powerful enough Mac, you can connect an HDMI display and an Apple Thunderbolt Display to Elgato Thunderbolt™ Dock at the same time.


PC:

When using a powerful enough PC that has two Thunderbolt™ ports, you can connect an HDMI display and an Apple Thunderbolt Display to Elgato Thunderbolt™ Dock at the same time.

Please Note:

On PC motherboards, only the boards with two Thunderbolt™ ports provide each port with two display signals.  In that setup, you would run one Thunderbolt™ cable from your PC to Elgato Thunderbolt™ Dock, but it would be carrying two display signals.

 
One HDMI Monitor and One DisplayPort Monitor


Mac:

When using a Mac, you can’t connect an HDMI monitor and DisplayPort monitor to Elgato Thunderbolt™ Dock at the same time.  The HDMI monitor will take precedence, and the DisplayPort monitor won't work.


PC:

When using a PC, you can’t connect an HDMI display and DisplayPort display to Elgato Thunderbolt™ Dock at the same time.  The HDMI display will take precedence, and the DisplayPort monitor won't work.


Please Note:

Any adapter that uses DisplayPort counts as a DisplayPort monitor for the sake of this article. That means you can't use a HDMI monitor and a DisplayPort adapter at the same time.  The HDMI monitor will take precedence, and the DisplayPort adapter won't work. 

For example, a DisplayPort to DVI adapter can't be used at the same time as a HDMI monitor.

 
Two Displays Via Two Thunderbolt™ Docks


Mac:

You can connect an HDMI display, and then connect the Elgato Thunderbolt™ Dock to another Elgato Thunderbolt™ Dock via a Thunderbolt™ cable.

Then, the second Elgato Thunderbolt™ Dock can connect to a display via Thunderbolt™, HDMI or DisplayPort.


PC:

When using a powerful enough PC that has two Thunderbolt™ ports, you can connect an HDMI display, and then connect Elgato Thunderbolt™ Dock to another Elgato Thunderbolt™ Dock via a Thunderbolt™ cable.

Then, the second Elgato Thunderbolt™ Dock can connect to a display via Thunderbolt™, HDMI or DisplayPort.

Please Note:

On PC motherboards, only the boards with two Thunderbolt™ ports provide each port with two display signals.  In that setup, you would run one Thunderbolt™ cable from your PC to Elgato Thunderbolt™ Dock, but it would be carrying two display signals.

This setup won't work on Macs in Bootcamp.

 
One Thunderbolt™ Dock Can Only Run Two Displays At A Time


Mac:

The Thunderbolt™ signal from a Mac has up to two display signals in it.  Therefore, no more than two monitors can be connected to Elgato Thunderbolt™ Dock at the same time.


PC:

The Thunderbolt™ signal from a PC usually only has one display signal in it. 

The exception is a PC that has two Thunderbolt™ ports. Only PC motherboards with two Thunderbolt™ ports provide each port with two display signals.  In that setup, you would run one Thunderbolt™ cable from your PC to Elgato Thunderbolt™ Dock, but it would be carrying two display signals.

No more than two monitors can be connected to Elgato Thunderbolt™ Dock at the same time.

 
Exceptional Cases


1) DisplayPort monitors will not function if connected to the Thunderbolt™ port of an Apple Thunderbolt Display.

2) Any monitors cascaded after an Apple Thunderbolt Display won't work.
