A Desktop PC is available in all common teaching rooms, meeting rooms (except rooms 1-203, 134-105, 142-202, 142-302 and 142-338) and GATCF computer labs for the purpose of showing presentations. An HDMI cable with commonly used adaptors are also available for those who wish to connect a laptop to the AV system in these rooms. The available cables and adaptors as well as the switching mechanisms vary from room to room. For details consult the VAVS - JCU Room finder (click on the virtual room link). Progressively, AV rooms are fitted with a wireless presenter through which a BYOD is connected to the AV system ( - wireless connection to Eduroam is a pre-requisite.
If the laptop results in the room display showing a black screen instead of the presentation, please ensure:
The HDMI cable is connected to the laptop
The laptop is set to duplicate or mirror its display
The laptop resolution is not exceeding 1920x1080
If the laptop results in the room display showing a green screen instead of the presentation, it is most likely a HDCP issue - contact VAVS for assistance.
