To mirror a new virtual display instead of the device screen:
scrcpy --new-display=1920x1080
scrcpy --new-display=1920x1080/420 # force 420 dpi
scrcpy --new-display # use the main display size and density
scrcpy --new-display=/240 # use the main display size and 240 dpi
On some devices, a launcher is available in the virtual display.
When no launcher is available (or if is explicitly disabled by
--no-vd-system-decorations
), the virtual display is
empty. In that case, you must start an Android
app.
For example:
scrcpy --new-display=1920x1080 --start-app=org.videolan.vlc
The app may itself be a launcher. For example, to run the open source Fossify Launcher:
scrcpy --new-display=1920x1080 --no-vd-system-decorations --start-app=org.fossify.home
By default, virtual display system decorations are enabled. To disable them, use
--no-vd-system-decorations
:
scrcpy --new-display --no-vd-system-decorations
This is useful for some devices which might display a broken UI, or to disable any default launcher UI available in virtual displays.
Note that if no app is started, no content will be rendered, so no video frame will be produced at all.
