+.. confval:: previewRenderer
+
+   :Path: $GLOBALS['TCA'][$table]['ctrl']
+   :type: string
+   :Scope: Display
+
+   Configures a backend preview for a content element.
+
+Examples
+========
+
+Have also a look at :ref:`t3coreapi:ConfigureCE-Preview` for more details.
+
+..  note::
+    The recommended location of the preview renderer configuration is in the
+    :php:`ctrl` array in your extension's :file:`Configuration/TCA/$table.php`
+    or :file:`Configuration/TCA/Overrides/$table.php` file. The former is used
+    when your extension is the one that creates the table, the latter is used
+    when you need to override TCA properties of tables added by the Core or
+    other extensions.
+
+Use for any record in a table
+-----------------------------
+
+This specifies the preview renderer to be used for any record in
+:sql:`tx_myextension_domain_model_mytable`:
+
+..  code-block:: php
+
+    $GLOBALS['TCA']['tx_myextension_domain_model_mytable']['ctrl']['previewRenderer']
+        = \MyVendor\MyExtension\Preview\PreviewRenderer::class;
+
+
+Table has a :php:`type` field/attribute
+---------------------------------------
+
+This specifies the preview renderer only for records of type :php:`$type` as
+determined by the :ref:`type field <types>` of your table.
+
+..  code-block:: php
+
+    $GLOBALS['TCA']['tx_myextension_domain_model_mytable']['types'][$type]['previewRenderer']
+        = \MyVendor\MyExtension\Preview\PreviewRenderer::class;
+
+Table has a :php:`subtype_value_field` setting
+----------------------------------------------
+
+If your table and field have a
+:ref:`subtype_value_field <types-properties-subtype-value-field>` TCA setting
+(like :sql:`tt_content.list_type`) and you want to register a preview renderer
+that applies only when that value is selected (for example, when a certain
+plugin type is selected and you can not match it with the type of the record
+alone):
+
+..  code-block:: php
+
+    $GLOBALS['TCA'][tx_myextension_domain_model_mytable]['types'][$type]['previewRenderer'][$subType]
+        = \MyVendor\MyExtension\Preview\PreviewRenderer::class;
+
+Where :php:`$type` is for example :php:`list` (indicating a plugin) and
+:php:`$subType` is the value of the :php:`list_type` field when the
+type of plugin you want to target is selected as plugin type.
