When Presenter starts up, it attempts to connect all the display adapters (monitors) to the last saved output assignments. It is quite possible that a particular monitor is no longer enabled or known by the system, in which case Presenter will search for the next available output. In a typical setup, this might be a custom monitor that has been previously configured to a portion of the primary display. While not useful for live use, a custom monitor shared with the primary (and most likely only) display will at least enable the user to work with Presenter for preparing run sheets, testing media or the like.
This situation is typical on laptop systems. Consider the following scenario:
1.In preparation for a live event, a projector is connected and enabled in Windows.
2.Presenter is started and the Main output is assigned to the external display adapter (Monitor #2)
3.While this display is connected, Presenter will remember the assignment on subsequent startups.
4.During the week, the user starts up Presenter in preparation for the following week's service. On this occasion there is no external display.
5.Presenter will detect that the display is not available and proceed to assign the next available output (such as a custom monitor that shares the laptop screen)
6.At the next live event with the projector attached, it is desirable to re-establish connection with the projector rather than use the custom monitor.
Under normal circumstances, any configuration changes made in Settings are preserved for future sessions. In this case, we want Presenter to re-establish the last monitor (projector output) and treat the custom monitor assignment as temporary, albeit necessary for viewing media output in the absence of the external display.
This temporary arrangement can be observed in this screenshot. Here, the output is assigned to MainTR, which is a custom view in the top 25% of the primary monitor. The entry includes Last Saved: DISPLAY2 indicating that it was previously assigned to that output. DISPLAY2 here is the device name provided by Windows.
The monitor details include this with a [Review] option under the current selection:
This alert indicates that Presenter will retry the display adapter on the next (and subsequent) start-ups. No further action is required on your part if you want this check to be done. If a monitor is available on this output (DISPLAY2), it will be re-established as the assigned monitor, overriding the current selection (Main TR in this example).
If you prefer the current monitor assignment to remain in place from now on, click the [Review] button to display a dialog window which will offer the option to dismiss the last saved monitor.
•Dismissing the previous monitor assignment applies to this current state only. It does not block future checks being performed.
•Presenter sends a query request to Windows for a list of available monitors. In most cases these are returned in a predicable sequence enabling them to be identified numerically. On rare occasions this order has been known to change. If more than one output is connected and disconnected (say, for both Main and Stage outputs), there is a small chance the new assignments may been reversed.
