Screen Sharing

In order to Screen Share (or use the Insert Screenshot tool located on the Whiteboard), you will want to install the Jigsaw Desktop Sharing extension for your browser and the Jigsaw App. This can be performed on the Test Your Computer page.

These extensions are currently supported in Chrome and Firefox only. So, if these Jigsaw tools are important to you, please join the session using Chrome or Firefox.

ADDITIONAL TIP: Bandwidth and Testing

A proper Internet connection is required to successfully use Jigsaw. The bandwidth specs will vary based upon your role during the session, Presenter or Attendee, but should be within the ranges outlined. These base speeds are guidelines as there are many factors that determine a "good" connection. For optimal results, use a wired connection. Wireless/WiFi can vary in strength and may result in audio/video delays. And, Hotspots are very unstable in connectivity and will most likely result in audio and/or video delays.

  • Download Speed – The maximum quantity of information that can be received by your computer from the Internet.
  • Upload Speed – The maximum quantity of information that can be sent by your computer to the Internet.
  • Ping – determines the delay between your computer and your network provider’s. Measure ping at:
  • Latency - the time it takes for a packet of data to make a round trip between two designated points.
  • Jitter – the variation over time of the latency across a network.

There are many factors that can contribute to a pleasant or challenging online experience with Jigsaw. The Jigsaw application is a live online tool requiring a uninterrupted connection. This is especially critical when watching videos, screen sharing, talking, or streaming web cams because these are live feeds. These outside factors must be considered for proper connectivity.

The Presenter and Attendees must ensure they are using the optimal:

  • Bandwidth - poor connections lead to application delays such as audio, chatting, web stream etc. For optimal results especially if you're a Presenter, use a wired connection. Wireless (WIFI) can vary in strength and may result in audio/video delays as well as other application delays.
  • CPU Power - as you increase the amount of video streaming in the session, the more CPU power becomes required. Typically, mobile devices such as tablets and mini computers used for surfing the web have the least processing power. Jigsaw recommends that no more than 2 video streams be active when using these types of devices.


As more video streams are added to a session, the system will optimize user's connectivity by reducing the quality of the streams at specific levels. Please reference the chart below.


Best results are found when 1 to 4 videos with video settings of 320X420.




See How to Install Jigsaw's Chrome Extension for Screen Sharing for details.

See How to Install Browser Extensions and the Jigsaw App from Test Page for details.

Note: Jigsaw recommends the resolution for the sharer to be no greater than 1280 x 720.

ADDITIONAL TIP: Browser or Network Settings

Jigsaw® is browser and firewall friendly. However, there may be times when personal or network settings require you to whitelist specific ports. Jigsaw has two types of traffic, general web page traffic, and streaming traffic for the live classrooms. Just like all other sites, our web pages use HTTP and HTTPS "protocols" (which just means the way in which the data being sent/received is organized). Our live classrooms use RTMP and RTMPT protocols. Typically, each protocol travels through pre‐determined “ports” and these are:


The following IP Addresses/URLs should be "whitelisted" (allowed) in customer firewall... - rtmp: 1935/tcp  *Flash Content (client application) - rtmp: 1935/tcp  *Desktop Sharing - Jigsaw App - webrtc: udp  *Desktop Sharing - Chrome Browser Extension - turn: udp/tcp  *Desktop Sharing - Chrome Browser Extension - http: 80/tcp  *Website - https: 443/tcp  *Web Services (used by all)


IF you can use URL's in your firewall whitelist, we recommend using the following URL's instead of IP addresses:


https - 443/tcp





rtmp - 1935/tcp (or rtmpt over 80/tcp)
