# Show the standby screen

Idle the display of the payment terminal.

[View source](/point-of-sale/shopper-engagement/display-data/idle-display.md)

In certain situations you may want to force the terminal to show the standby screen. This screen shows your own branded [logo](/point-of-sale/design-your-integration/determine-account-structure/configure-features#terminal-customization-hardware-features-and-receipts) as it is usually shown when no other process is going on.

## Switch to the standby screen

To force the payment terminal to show the standby screen, we recommend using a display request with `PredefinedContent`. This works regardless of the terminal model.

There is also another method that we support. This uses `OutputXHTML` in the display request. However, it only works on terminals that accept XHTML: M400, P400 Plus, and V400m.

Select the tabs below for details.

### Tab: Generic - PredefinedContent

1. Make a [Terminal API](/point-of-sale/design-your-integration/terminal-api) display request, specifying:

   * The standard [`SaleToPOIRequest.MessageHeader` ](/point-of-sale/design-your-integration/terminal-api#request-message-header)object, with `MessageClass` set to **Device** and `MessageCategory` set to **Display**.
