 - `-t --title`: set a custom window title for the video stream. The default title is "reStream". This option is disabled when using `-o --output`
 - `-u --unsecure-connection`: send framebuffer data over an unencrypted TCP-connection, resulting in more fps and less load on the reMarkable. See [Netcat](#netcat) for installation instructions.
 - `-e --extra-filters`: pass extra video-filters to ffplay/ffmpeg (pass as a comma-seperated list)
+- `--dark-mode`: Dark mode. Make background black and text white.
