Cuttlefish: Multi-display
Stay organized with collections
Save and categorize content based on your preferences.
The Cuttlefish multi-display feature lets you create Cuttlefish devices with
multiple displays to emulate devices such as foldable phones and Android Auto
devices. Figure 1 shows an example of a Cuttlefish device with multiple
displays.

Launch with multiple displays
To configure a Cuttlefish device to have multiple displays during launch, use
the --display command line flag. For example:
cvd create \
--display=width=1080,height=600 \
--display=width=400,height=600,dpi=120 \
--display=width=800,height=600,refresh_rate_hz=30
App usage
To start an app on a specific display, use the --display flag. For example,
to launch the dialer app on display 1, run the following command.
adb shell am start-activity -n com.android.dialer/.main.impl.MainActivity --display 1
