Think you have to right-click on the view and "Redefine with current view setting" to re-save the view with the desired settings.

If you just open it in Adobe Reader and zoom in you should see if its sharp or not.

Had this question at the office and solved it by right-clicking on the AC-desktop icon, going to properties and changing the DPI-scale to "System". See attached screeenshot.
