Window
Disable window
To disable window (may be useful for recording or for playing audio only):
scrcpy --no-window --record=file.mp4
# Ctrl+C to interrupt
Title
By default, the window title is the device model. It can be changed:
scrcpy --window-title='My device'
Position and size
The initial window position and size may be specified:
scrcpy --window-x=100 --window-y=100 --window-width=800 --window-height=600
By default, the window aspect ratio is preserved when resizing. To disable this behavior:
scrcpy --no-window-aspect-ratio-lock
Borderless
To disable window decorations:
scrcpy --window-borderless
Always on top
To keep the window always on top:
scrcpy --always-on-top
Fullscreen
The app may be started directly in fullscreen:
scrcpy --fullscreen
scrcpy -f # short version
Fullscreen mode can then be toggled dynamically with MOD+f (see shortcuts).
Disable screensaver
By default, scrcpy does not prevent the screensaver from running on the computer. To disable it:
scrcpy --disable-screensaver
Render fit
By default, the video stream is rendered in letterbox mode: the content fits the window as best as possible while preserving the aspect ratio.
For flex displays, the display is continuously resized to match the window, so render fit is disabled: the content is rendered at the top-left corner, without scaling.
It is also possible to stretch the content to fit the window without
preserving the aspect ratio (--render-fit=stretched).
scrcpy --render-fit=letterbox # default
scrcpy --render-fit=disabled # default for flex displays
scrcpy --render-fit=stretched
