Running a slideshow on a projector using Labview

[RV1]

I am developing a Labview program that needs to display a slideshow on a projector. I have a graphics card with two ports, one connected to my monitor and one connected to the projector. I need to have the VI Front panel displayed on the monitor and run the slide show on the projector.

Currently, I have a main VI that calls a sub-VI to display some images in a sequence. I used the “VI properties -> Windows run time position “ option to display the main VI on my monitor and the sub-VI on the projector. The slide show appears to run fine. However, the slideshow on the projector is embedded within a sub-VI front panel along with the Labview GUI. Is there any way to turn off the sub-VI front panel and the Labview GUI, so that I can just display the raw images on my projector? The sub-VI is launched from the main VI and terminates after a few minutes, so I do not need to run or stop or do anything with the sub-VI.

When I did this recently I just made the Display subVI larger than the projector. I sized the picture control (indicator) so that it completely filled the projected screen area. The rest of the subVI front panel was off the screen. Still there, but not visible.

Have you tried the Front Panel>Run-Time Position method (new in LV8.2, nut sure about 8.0)? It changes the front panel to Maximized, Minimized, etc, and has an additional parameter "Monitor". If you put it on Maximize, monitor 1, it should maximize on the projector.
