JPEG Saver config — Multi-monitor dialog
If you only have one monitor you will not be shown this dialog, which lets you configure how JPEG Saver displays things on each screen.
- Main display selection
- Main display mode selection
- Other displays selection
- Stagger updates checkbox
- Transitions on all displays checkbox
Main display
This drop-down box lists the displays that are available on your computer, numbered the same way as in the Display Properties section of the Control Panel. The monitor you select here will be the one that JPEG Saver displays transitions and real-time items on.
The monitor name comes from the EDID information stored in the registry. This could be incorrect, but it is more likely to be useful than the “Generic PnP Monitor” that other Windows functions report. The resolution shown after the monitor name is the current resolution of the screen.
The “Windows main” option at the start of the list means that JPEG Saver should use whichever display you have set as your primary in the Control Panel.
Span across screens
This option is at the bottom of the list of monitors - enabling it makes JPEG Saver draw on one window that spans across all the displays. How well this works depends on your graphics card and the positions and sizes of the different screens, but the effect can be quite enjoyable.
Screen mode
This is the same as the display mode selection from the main dialog, populated with the modes supported by your selected main display.
Other displays
This drop-down box allows you to choose what is shown on the other displays – any display that is not the one selected as the “Main display”. The options are:
- Previous image
- The image previously shown on the main display is shown on all the other displays.
- Same image
- The same image is shown on all displays.
- New image
- A new image from the sequence is shown on each display.
- Background only
- The background of every screen is filled without a foreground image.
- Blank screen
- Other displays show a plain black screen.
- Nothing
- JPEG Saver doesn't cover the display at all and the desktop will show through. Depending on your operating system version, security settings and how JPEG Saver is started this could be the screen saver desktop, which is not very useful.
Stagger updates
With this option enabled, images will be loaded on secondary screens at regular intervals between the primary screen updates. For example, if you have three screens and your change delay is set to 30 seconds, the primary display will update every 30 seconds, the second display will update 10 seconds after the primary and the third screen will update 10 seconds after that. The update interval is the change delay divided by the number of screens.
Transitions on all displays
This option enables Direct3D transitions for all the displays. This works best when the “Stagger updates” option is enabled, since it means the transitions are not happening on multiple screens at the same time.
