Poster Box

Rotating display of Plex posters meant for a vertical TV or monitor.

Available as a binary and Docker container.


You can run Poster Box in one of two ways:


Install on Mac OS with:

$ brew install JakeWharton/repo/posterbox

For other platforms, download ZIP from latest release and run bin/posterbox or bin/posterbox.bat.

$ posterbox --help
Usage: posterbox [OPTIONS] CONFIG

  HTTP server for Poster Box frontend

  --port PORT  Port for the HTTP server (default 9931)
  -h, --help   Show this message and exit

  CONFIG  TOML config file


The container starts the webserver on port 9931. It expects to load the configuration TOML from /config/config.toml so mount a volume accordingly.

The configuration file allows customization of behavior and specifies the source of content. All top-level keys and sections are optional. An empty configuration file is technically valid, but will result in no content being displayed.

# Duration each item is displayed as an ISO 8601 duration string (optional).
# See
#  Value: must be positive duration
#  Default: "PT15S" (15 seconds)
itemDisplayDuration = "PT10S"

# Transition between items (optional).
#  Value: "none", "fade", "crossfade", "slide-right", or "slide-left"
#  Default: "fade"
itemTransition = "slide-right"

# Use Plex as a content source.
#  This section is optional but has required keys if it is present.
# Plex host URL (required).
#  Value: String containing DNS hostname or IP with protocol and optional port.
host = "http://plexms:32800"
# Plex authentication token (required).

# Libraries from which to pull posters (optional). No matter the contents of this array,
# only entries of type "movie" or "show" will be used.
#  Value: Array of case-sensitive library names or null to use all available libraries.
#  Default: null
libraries = [ "Movies", "TV Shows" ]
# Minimum rating cut-off for poster inclusion (optional). Content with no rating is
# treated as having a rating of 0. Audience rating takes precedence over critic rating.
#  Value: Whole number in the range [0, 100]
#  Default: 0
minimumRating = 40
# Duration between synchronizing items from Plex server as an ISO 8601 duration
# string (optional). See

To run the latest code build with ./gradlew installDist. This will put the application into build/install/posterbox/. From there you can use the command-line instructions to run.

The Docker container can be built with docker build ..


Poster Box was inspired by Posterr which is a far more feature-filled and customizable tool. Posterr was not able to run smoothly on my Raspberry Pi Zero due to its use of a jQuery-based carousel and creating DOM nodes for every poster when loaded. Poster Box has only two sets of DOM elements which are updated when off-screen and animated using CSS animations. If you like Poster Box but wish it had more features and integrated with more tools you should try Posterr!
