+
+  Routine Description:
+    Return the current video mode information.
+
+  Arguments:
+    This                  - Protocol instance pointer.
+    ChildHandle           - A child handle produced by the Graphics Output EFI
+                            driver that represents a video output device. 
+    Attributes            - The attributes associated with ChildHandle video output device.
+    EdidSize              - A pointer to the size, in bytes, of the Edid buffer.
+    Edid                  - A pointer to callee allocated buffer that contains the EDID that
+                            should be used for ChildHandle. A value of NULL 
+                            represents no EDID override for ChildHandle.
+
+  Returns:
+    EFI_SUCCESS           - Valid overrides returned for ChildHandle.
+    EFI_UNSUPPORTED       - ChildHandle has no overrides.
