JPEG Saver config — Per-display options dialog
This dialog is available whether you have multiple monitors or not, and can be used to override the values of many of the options that are set from the other sections of the config dialog.
Display selection
The first input in the dialog is a drop down box with 64 displays listed. This allows you to configure options for displays or windows that are not currently connected. Which physical monitor corresponds with each display is down to Windows and how they are plugged in - so it is up to you to check which is which.
Displays that have overrides stored appear in the list with a filled circle (like this "●") after the display number.
Reset button
Just across from the display drop-down is a Reset button - this clears all the settings for the selected display and reverts to using the global options.
Option list
The main bulk of the dialog is taken up by the option list. This shows all the options that can be overridden for each display.
To override an option, click the checkbox on the left of the option. The value section of the table turns into an input where you can select or enter the new value. For options where the checkbox is not checked, the global value is shown.
To revert an option to the global value, uncheck the checkbox.
The dialog will confirm your changes when you click OK or choose another display from the drop-down box.
Note: this dialog is not very intelligent - you can override the values for all of the options, but there is only basic validation and your chosen values might not be useful. Some options depend on other options, for example "Resize small - fit" is ignored when simple resizing is enabled.
