A hibernating device is a device that is on, but has a screen that is "off". For Windows, Linux, and ChromeOS devices this means that the Cortex Player will be displaying a black screen while hibernating. For LG webOS devices, we will actually turn off the screen.
You can edit your network's display operation schedule to set the hours you want your devices to be hibernating.
You can view the amount of hibernating devices on the top of the device list page. The online device count is broken down to include both online and hibernating devices.
You can also see which devices are hibernating in the status column on the device list table.
If you drill down on a hibernating device, you will also see this information reflected in the player status and strategy section of the overview page.
