Text and images are blurry on Windows

The later Anki 2.0 releases increase the size of the text and images to make them easier to see on high resolution displays, but it means that everything is a little less sharp. If you preferred the old behaviour where things were smaller but sharper, you can return to this old behaviour by following the steps on the following link:

Please note that Anki 2.0 is no longer supported - if you're not using a lot of old add-ons, a better option would be to upgrade to the latest Anki 2.1 release, which has better support for high resolution displays: https://apps.ankiweb.net/
