Connect other devices and display with Surface Hub

You can connect other device to your Surface Hub to display content. This topic describes guest mode and replacement PC modes that is available through a wired connection.

Guest mode

Guest mode uses a wired connection, so people can display content from their devices to the Surface Hub. If the source device is Windows based, that device can also provide Touchback and Inkback. Surface Hub's internal PC takes video and audio from the connected device and displays them on the Surface Hub. If Surface Hub encounters an HDCP signal, the source will be re-routed through an alternate path, allowing the source to be displayed full-screen without violating HDCP requirements.

Ports

Use these ports on the Surface Hub for the guest mode.

Interface	Type	Description	Capabilities
Display Port 1.1a	Video input	Guest input #1	Support simultaneous guest input display with guest input #2 and guest input #3 (one full resolution, two thumbnail). HDCP compliant in bypass mode Touchback enabled
HDMI 1.4	Video input	Guest input #2	Support simultaneous guest input display with guest input #1 and guest input #3 (one full resolution, two thumbnail). HDCP compliant in bypass mode Touchback enabled
VGA	Video input	Guest input #3	Support simultaneous guest input display with guest input #1 and guest input #2 (one full resolution, two thumbnail). HDCP compliant in bypass mode Touchback enabled
3.5 mm jack	Audio input	Analog audio input	Ingest into Surface Hub PC, usually with the VGA video input.
USB 2.0, type B	USB out	Touchback	Provides access to the HID input devices mouse, touch, keyboard, and stylus back to the guest PC.

 

Port locations

These are the port connections used for guest mode on the 55" and 84" Surface Hubs.

Port enumeration

When a Surface hub is connected to guest computer with the wired connect USB port, a number of USB devices are discovered and configured. These peripheral devices are created for touchback and inkback. The peripheral devices can viewed in Device Manager. Device Manager will show duplicate names for some devices.

Human interface devices

• HID-compliant consumer control device

• HID-compliant pen

• HID-compliant pen (duplicate item)

• HID-compliant pen (duplicate item)

• HID-compliant touch screen

• USB Input Device

• USB Input Device (duplicate item)

Keyboards

• Standard PS/2 keyboard

Mice and other pointing devices

• HID-compliant mouse

Universal serial bus controllers

• Generic USB hub

• USB composite device

Guest mode connectivity

Your choice of video cable will be determined by what is available from your source input. The Surface Hub has three choices of video input, DisplayPort, HDMI and VGA. Please refer to the below chart for available resolutions.

Signal Type	Resolution	Frame rate	HDMI - RGB	DisplayPort	VGA
PC	640 x 480	59.94/60	X	X	X
PC	720 x 480	59.94/60	X	X
PC	1024 x 768	60	X	X	X
HDTV	720p	59.94/60	X	X	X
HDTV	1080p	59.94/60	X	X	X

 

Source audio is provided by DisplayPort and HDMI cables. If you must use VGA, Surface Hub has an audio input port that uses a 3.5 mm plug. Surface Hub also uses a USB cable that provides touch and inkback from the Surface Hub to compatible Windows 10 devices. The USB cable can be used with any video input that is already connected with a cable.

Someone using guest mode to connect a PC would use one of these options:

DisplayPort -- DisplayPort cable and USB 2.0 cable

HDMI -- HDMI cable and USB 2.0 cable

VGA -- VGA cable, 3.5 mm audio cable, and USB 2.0 cable

If the computer you are using for guest mode is not compatible with Touch and Inkback, then you won't need the USB cable.

Replacement PC mode

In replacement PC mode, the embedded computer of the Surface Hub is turned off and an external PC is connected to the Surface Hub. Connections to replacement PC ports give access to key peripherals on the Surface Hub, including the screen, pen, and touch features. This does mean that your Surface Hub won’t have the benefit of the Windows Team experience, but you will have the flexibility offered by providing and managing your own Windows computer.

Software requirements

You can run Surface Hub in replacement PC mode with 64-bit versions of Windows 10 Home, Windows 10 Pro and Windows 10 Enterprise. You can download the Surface Hub Replacement PC driver package from the Microsoft download center. We recommend that you install these drivers on any computer you plan to use as a replacement PC.

Hardware requirements

Surface Hub is compatible with a range of hardware. Choose the processor and memory confirmation for your replacement PC so that it supports the programs you'll be using. Your replacement PC hardware needs to support 64-bit versions of Windows 10.

Graphics adapter

In replacement PC mode, Surface Hub supports any graphics adapter that can produce a DisplayPort signal. You'll improve your experience with a graphics adapter that can match Surface Hub's resolution and refresh rate. For example, though the best and recommended replacement PC experience on the Surface Hub is with a 120Hz video signal, 60Hz video signals are also supported.

55" Surface Hubs - For best experience, use a graphics card capable of 1080p resolution at 120Hz.

84" Surface Hubs - For best experience, use a graphics card capable of outputting four DisplayPort 1.2 streams to produce 2160p at 120Hz (3840 x 2160 at 120Hz vertical refresh). We've verified that this works with the NVIDIA Quadro K2200, NVIDIA Quadro K4200, and NVIDIA Quadro M6000. These are not the only graphics cards - others are available from other vendors.

Check directly with graphics card vendors for the latest drivers.
