When the Site Type is set to “PC” the web browser screen size defaults to 1000px wide × 750px tall.
Additionally, the maximum vertical size is 5000px.
Note that the screen size can be specified during scan creation under “Screen Size”.
Three sizes are available for specification: “1000px × 750px”, “1200 × 900px”, and “1920px × 1440px”.
Generally, the default screen size setting is sufficient.
However, if certain buttons become hidden and prevent proper crawling, or when scanning sites where content like headers toggles visibility based on screen width, try changing to a larger screen size setting to see if crawling becomes possible.
