Configuring and Deploying AEM Screens

This page shows how to install and configure the Screens players on your devices.

Server Configuration

Health Check Framework

The Health Check framework allows the user to check if two necessary configurations are set up before running an AEM Screens project.

It allows the user to verify the following two configuration checks to run an AEM Screens project, that is, to check the state of the following two filters:

1. Allow Empty Referrer
2. https

Follow the steps below to check if these two vital configurations are enabled for AEM Screens:

1. Navigate to Adobe Experience Manager Web Console Sling Health Check.

   

2. Click on Execute selected health checks to run the validation for two properties listed above.

   If both the filters are enabled, then the Screens Configuration Health Service shows the Result as OK with both the configurations as enabled.

   

   If one or both the filters are disabled, then an alert is displayed for the user, as shown in the figure below.

   The following alert showcases if both the filters are disabled:

Enable Touch UI for AEM Screens

AEM Screens requires TOUCH UI and will not work with CLASSIC UI of Adobe Experience Manager (AEM).

Alternatively, you can also perform the same setting using yourAuthorInstance -> tools (hammer icon) -> Operations -> Web Console and search for WCM Authoring UI Mode Service.

AEM in NOSAMPLECONTENT runmode

Running AEM in production uses the NOSAMPLECONTENT runmode. Remove the X-Frame-Options=SAMEORIGIN header (in the additional response header section) from

https://localhost:4502/system/console/configMgr/org.apache.sling.engine.impl.SlingMainServlet.

This is required for the AEM Screens Player to play online channels.

Password Restrictions

You can configure DeviceServiceImpl from the link below to enable password restriction while creating the password for the screens device users:
