When you insert the IdeaShare Key into a large screen, the large screen automatically detects its version and checks whether it matches the version of the IdeaShare Key software. If not, the IdeaShare Key will automatically upgrade.

If the version of the IdeaShare Key software on the large screen does not meet the requirements, you can upgrade the software first, and then insert the IdeaShare Key into the large screen for upgrade. Currently, independent upgrade can be implemented using a USB flash drive, web interface on the large screen, and SMC. For upgrade on the web interface, log in to the web interface, choose Maintenance > Upgrade > Projector, select an upgrade file on the local host, and click Upload.
