We now have 3 different kinds of adapters/dongles at the circulation desk for MacBooks, iPads, and iPhones to plug your device into the HDMI cables at the large monitors in the Reilly Learning Commons. The adapters are Mini DisplayPort to HDMI, 30 pin to HDMI, and Lightning to HDMI. If your device requires a different adapter, please let us know and we will look at getting other options.
