100% Zoom Different in PDF-XChange and Adobe Reader 9

See the attached screenshot that shows a significant difference in size on screen for documents viewed at 100% zoom in PDF-XChange and Adobe Reader.

Not an important issue, but quite a significant difference nevertheless. I am using nVidia GeoForce graphics on a 1280 x 1024 monitor if that is relevant.

Document size in pixels with 100% depends on screen DPI. Viewer use default windows screen DPI (usually reported by windows as 96), but Adobe by default use different DPI (often 110 DPI). This will result visual difference of documents size with same zoom in Viewer and Adobe products. You can check and change DPI settings on Page Display tab in both Viewer and Adobe settings.

Thanks. I fixed Adobe Reader so that it now displays the page at 96 dpi and is the same size on screen (near enough) as an A4 sheet of paper.
