You can use Miracast and Chromecast with a K165 or K175 device.

Miracast is a standard protocol for wireless mirroring of your device on any other Miracast-capable device, such as a TV or monitor. You can mirror your K165 or K175 device screen using the Cast option in the Notifications area.

Chromecast is a Google application for streaming multimedia content from Chromecast-compatible services, such as Netflix, which are running on your device to an external Chromecast device. Chromecast does not mirror the device screen, so you can continue making calls or performing other tasks on your Avaya Vantage™ device.
