Viewing a resource
From MoodleDocs
Resources may display in the same or a new window and different sizes.
To change how a Text, a Web Page or a Link resource displays:
- click the "Show Setting" button next to Window under the HTML Editor field.
Note: the default window size for a New Window is 620 by 450. These defaults and many more can be changed by the administrator under Admin > Modules > Activities > Resource
Display of embedded PDF
If you are not seeing PDFs embedded in the page properly (and just seeing a download link), you may need to upgrade to a more recent version of Adobe Acrobat Reader
