Recommended System Specs

Operating System

Our conference platform, BigMarker, requires Windows XP, Vista, or 7 or later; Mac OS X 10.6 or later; or Linux RHEL 5.6 or later, openSUSE 11.3 or later, or Ubuntu 10.04 or later.

Web Browser

To attend a conference session, you’ll need to be on the latest version of Chrome, Firefox, Safari, Edge, or Opera.

We recommend using Chrome or Firefox for the best possible experience.

Internet Connection

The minimum download and upload speed to join a session as an attendee without interruption is 2 Mbps. If you fail to meet the minimum requirement, you may experience technical difficulties in the session, including losing connection and poor audio and video.

To test your internet speed, visit or

Firewall or Proxy

If you have a network firewall enabled, you may see a black video screen or a “Connection Can't Be Established” warning, or you may drop connection regularly.

If possible, contact your IT department and have them open the necessary ports.

Minimum requirement: The default assumption is that TCP ports 80 and 443 are open. Some firewall rules only allow for TCP traffic over port 443; make sure that all traffic can pass over this port. If you continue to experience issues, you may need to follow the “Best experience” suggestion below.

Best experience: In addition to the minimum requirements being met, we recommend that UDP ports 1025 - 65535 be open.
