VNC in VR: Synchronized Virtual Desktops

WHAT: We load an HTML5-based VNC viewer into a web entity in the virtual world. It communicates over a websockets proxy layer with a VNC server running on my machine. Anyone with the IP address and the password can view or, with permission, interact.

One of my favorite use cases for VNC is for remote research stations, like the Keck Observatory or Polar Bears International, where multiple people need to access far away systems. Collaboration is hard; collaboration across the world is even harder! But what if you could stand in a familiar, built space with your co-investigators? What if you could observe, design, and respond together? How would that change the way you worked? Keep notes on a whiteboard; point at part of the screen to explain what you mean.

Whether you’re an arctic explorer or a systems administrator, chances are you’ve used a VNC server. If you’ve ever wanted to surround yourself with screens and set up the ultimate Star Trek bridge to monitor your traffic, or if you simply forgot a file on your work computer, today’s your lucky day!

There’s some great stand alone software out there exploring this space, like Virtual Desktop or BigScreen. Below, I’ll show how to use High Fidelity to add this experience to a shared multi-user environment. Oh, and did I mention we’re open-source and free?

While there are definitely a few kinks to work out, without any coding you can be up and running in no time at all. We hope that you will share your ideas, concepts, and experiments in this space.

You can reach me at james@highfidelity.io with any questions, comments, or corrections. Thanks!

Note: This tutorial was created on Windows 10, 64-bit. The general steps should work on other platforms, but I haven’t tested them. I’ll update this post with any submissions from our Linux / OS X users.

Additional Note: I use a two monitor setup here: one for Interface, and the other for the ‘remote’ desktop.

TLDR: Desktop Window → VNC Server → Websockify Running on Node.js → VNC Client from Web Entity inside of Interface

VNC Server

— — — — — — —


  1. Install Ultra VNC (you just need the server).
  2. Open Ultra VNC Server.
  3. Right-click on the Ultra VNC in your system tray and choose Admin Properties.
  4. In the ‘Authentication’ section, add a password.
  5. Make sure to note the Port Number listed in the Ports section (mine is 5901)
  6. Click OK

HTML-based VNC client

  1. Download the file below and extract it to a folder on your Desktop. It’s just the basics that you need to run noVNC.

Websockets Layer — TCP to Websockets proxy

*Note — this is what held me up for a while: trying to get websockify to run via the instructions in their repository with python, I always ran into errors I couldn’t resolve. However, the node.js version works great!


  1. Install node.js
  2. Open Windows Powershell (or your preferred terminal)
  3. Install websockify by using npm, the package manager installed with node.js
  • npm install -g websockify
  1. Type
  • websockify 8787 localhost:5901 — web
  1. Then drag the noVNC-thin folder onto the shell window. This will paste its path. The whole command will look like this:
  • websockify 8787 localhost:5901 — web /C/Users/james/Desktop/HighFidelity_VNC_Tutorial/noVNC-thin
  1. Press Enter to start running Websockify.
 Run Websockify in High Fidelity VR

Virtual World (High Fidelity)

— — — — — — — — — — — — — — -


  1. Click the Edit button in Interface to open the Edit Toolbar.
  2. Click Web.
  3. In the Entity Properties for the Web Entity, change the sourceURL to:
  1. Close the Edit Toolbar by clicking the Edit Button again.
  2. Click in the web entity and enter your password.
  3. Click Connect.
Add VNC to your toolbar in High Fidelity
 Adding VNC to High Fidelity Toolbar

Now you should see your desktop window! Woohoo! 

Adding your desktop window to High Fidelity VR domain

Share Desktop With Others:

— — — — — — — — — — — — — 

If you want others on the internet to be able to see your desktop, you need to set the sourceURL of the Web Entity to your public IP address. If your public IP address doesn’t directly map to where you’re serving the noVNC files, you’ll need to open up those ports yourself.

Note: others will still have to type the password to see your desktop, so you’re not broadcasting it just anyone!

  1. Open the Entity Properties for the Web Entity again, but this time set the sourceURL to:

We’ve only just scratched the surface of what’s possible. There are a variety of settings for both the VNC server and client that can be used to improve your individual experience. Furthermore, you could connect to a virtual desktop that isn’t running on your own machine, but rather in the cloud on a service like Amazon’s EC2. Open multiple connections for multiple desktops; figure out how to stream sound; give tutorials! Go for it.
