You will need to provide your own laptop to present from. This also means that your presentation can be in whatever file type you want to present with since it is on your machine. Don’t forget the backups in case there are issues with your machine.
For those who do not have a HDMI port on the device you will be using to present from you will need to bring your own adapter/dongle. For consistency for presenters (ensuring 16:9 ratio and audio) as well as the AV team at the conference center we are going with one option and you should be prepared to connect via * HDMI. These adapters are relatively inexpensive and can be found in most office supply stores as well as online.
*This is not an endorsement of this particular product but rather just an example of what to look for.
