Short Name: SyncDisp

Requires: Base Development System

Class: Control Properties

To Use: Create a property.

When TRUE, enables synchronous display that shows every update to a data value in a control or indicator. When FALSE, asynchronous display permits the execution system to reduce updates to a slower rate and spend more time executing VIs.

In multithreaded systems, you can use this property to set whether to defer updates for controls and indicators. With asynchronous displays, after the execution system passes data to front panel controls and indicators, it can immediately continue execution.

This property is similar to the Advanced»Synchronous Display option on the shortcut menu of controls and indicators.

You also can use the Defer Panel Updates property to defer all new requests for front panel updates.
