We recommend using external speakers or headphones to listen to the performance.
If your computer has an HDMI port, you can connect this to your TV and view the performance there. You can also watch on TV via Apple Airplay by using the Safari browser and clicking the Airplay icon in the video window, or by clicking the Chromecast icon in the video window when using Google Chrome browser on a mobile device.
Vimeo can also connect to your TV through the Roku app; more information can be found here.
