-the computer. This option is useful when [recording](recording.md) or when
+window. This option is available if either [recording](recording.md) or
 [v4l2](#video4linux) is enabled:
 
 ```bash
-scrcpy --v4l2-sink=/dev/video2 --no-playback
+scrcpy --v4l2-sink=/dev/video2 --no-display
-scrcpy --record=file.mkv --no-playback
+scrcpy --record=file.mkv --no-display
 ```
 
-It is also possible to disable video and audio playback separately:
-
-```bash
-# Send video to V4L2 sink without playing it, but keep audio playback
-scrcpy --v4l2-sink=/dev/video2 --no-video-playback
-
-# Record both video and audio, but only play video
-scrcpy --record=file.mkv --no-audio-playback
-```
-
-
-## No video
-
-To disable video forwarding completely, so that only audio is forwarded:
-
-```
-scrcpy --no-video
-```
-
