You can currently use DEON on Microsoft Surface Hubs of the 1st generation (84 and 55 inches) by connecting an external PC. For optimal performance, please follow the instructions below.
NOTE: We have discontinued the previous DEON UWP app for Surface Hub, which could be installed on the integrated PC, because new DEON features could not be ported to the limited UWP operating system. The release of an entirely new solution that will overcome some of the limitations and still enable the use of the integrated PC is planned for the end of this year. Until then, please connect an external PC to the hub.
When using an external PC to run DEON on the Surface Hub 84 or 55, we strongly recommend switching the hub to the “Replacement‑PC‑Mode”.
This gives you the full performance and all features of DEON Windows Version.
IMPORTANT: The high refresh rate of 120 Hz at the full UHD resolution of 3,840 × 2,160 is only possible in “Replacement‑PC‑Mode”. Without this you can only use the “Guest‑Mode”, which allows a maximum of 30 Hz at full resolution. The multitouch and stylus operation at 30 Hz is almost unusable.
You can switch back from “Replacement‑PC‑Mode” to the normal mode at any time without losing configurations.
If you cannot use the “Replacement‑PC‑Mode” for any reason, we recommend lowering your PC’s resolution to Full HD to achieve at least a 60 Hz refresh rate.
What you need to operate a Surface Hub 84 in Replacement-PC-Mode at 120Hz UHD:
- A PC with two video outputs that can display four DisplayPort 1.2 streams (two streams per cable). NOTE: Using only one output still works, but offers a lower refresh rate and/or lower resolution.
- Two video cables from the PC output (DP or Mini DP or USB-C Thunderbolt 3 or mixed) to the two DisplayPort inputs of the Surface Hub. Short cables (<=2m) recommended.
- A USB cable to use Touch, Stylus, Cameras, and the Surface Hub's microphone array.
Connecting the Surface Hub 84 in Replacement-PC-Mode:
- Turn off the Surface Hub: First power it down using the side button and then use the main power switch at the bottom next to the power cable to turn it off completely.
Remove the cover from the Replacement PC slot on the bottom of the hub:
- Set the small DIP switch to Replacement-PC mode.
- Connect two video cables from the PC (DP or Mini DP or USB-C Thunderbolt 3 or mixed) to the two DisplayPort inputs (short (<=2m), 4K-capable cables recommended). Connect a USB cable from the PC to the USB port "Internal Devices".
- Turn on the Surface Hub and select "PC" as input (use the input selection button on the side of the Surface Hub). Do not use "DP", as this only refers to the additional single DisplayPort input.
- Turn on your PC.
If the hub is not automatically recognized with 3840×2160 @ 120Hz:
Check that you are not using the “Duplicate screen” mode in Windows, but “Single screen only” use.
To check whether you are working with 3840×2160 @ 120Hz:
Search and open “Display settings”. Scroll down and click on “Advanced display settings”. - If touch, stylus, microphone and cameras are not recognized by default, you can download the drivers from Microsoft: SurfaceHubReplacementPCDrivers.1.1.003.msi
