You can control the resolution of graphics placed in your document. You can change the display settings for the entire document or for individual graphics. You can also change a setting that either allows or overrides the display settings for individual documents.
A document always opens using the default Display Performance preferences. You can change the display performance of a document while it is open, but the setting won’t be saved with the document.
If you’ve set the display performance of any images separately, you can override the settings so all objects use the same settings.
Select Object > Display Performance, and choose a display setting.
Right-click (Windows) or Control-click (Mac OS) the image, and choose a display setting from the Display Performance submenu.
These options control how graphics are displayed on the screen, but they do not affect the print quality or exported output.
Use Display Performance preferences to set the default option used to open all documents, and customize the settings that define those options. Each display option has separate settings for displaying raster images, vector graphics, and transparencies.
The Display Performance preferences let you set the default display option, which InDesign uses for every document. You can change a document’s display performance using the View menu, or change the setting for individual objects using the Object menu. For example, if you work on projects that contain numerous high-resolution photos (such as a catalog), you may prefer to have all your documents open quickly. You can set the default display option to Fast. When you want to see the images in more detail, you can switch the document view to Typical or High Quality (leaving the preference set to Fast).
You can also choose to view or override display settings applied to individual objects. If Preserve Object-Level Display Settings is selected, any settings applied to objects are saved with the document.
