When I bring up a PDF with Adobe Reader DC, the font is very thin, pixelated/jagged, and hard to read. If I bring it up with ANY browser, the font is broader, without a trace of pixelation, and easy to read. Is there a way to set Adobe Reader to use a font that is readable on the screen? (I can't find a way.)
Are you on a Mac or Windows machine and what is the version?
Navigate to Adobe Reader's Preferences from Edit>Preferences(Windows), Adobe Acrobat/Reader>Preferences(Mac)>Page Display>under 'Rendering'> Select 'use local fonts'>Click OK>Restart the application and open the PDF file again and check.
Make sure you have the latest version of Adobe Reader 19.010.20069 installed, check for any pending updates from help>check for updates, reboot the machine after updating Adobe Reader.
In Adobe Reader, Select the Edit menu - Preferences.
Under Categories in the left-hand column, select Page Display.
To the right is a section named "Rendering." Under Rendering, there is a drop down menu to the right of the words "Smooth Text." In the drop down menu, select "For Monitor" for an external monitor or "For Laptop/LCD Screens" for your laptop.
