-The Android screen automatically turns off after some delay.

-To change this delay while scrcpy is running:
-
-```bash
-scrcpy --screen-off-timeout=300  # 300 seconds (5 minutes)

-
-The initial value is restored on exit.

-It is possible to change this setting manually:
-
-```bash
-# get the current screen_off_timeout value
-adb shell settings get system screen_off_timeout
-# set a new value (in milliseconds)
-adb shell settings put system screen_off_timeout 30000
