Simply plug a Micro USB cable from the adaptor into the USB port and audio will be available when you deliver your presentation.The adaptor can also be used for connecting your laptop or desktop computer to your monitor and speakers. The adaptor and connected cables can be placed nicely at the back of your monitor to create a tidy set-up between all of your devices.This lightweight adaptor is compatible with Intel® Thunderbolt™, when connected directly to a supporting DisplayPort over Thunderbolt™ I/O port, and supports resolutions up to 1920 x 1200 (WUXGA).
