As with all software releases, Windows 8.1 comes with a few bugs. One that has been annoying many people since updating to 8.1 is the display settings. Users have been describing bold, blurry (fuzzy) and hard-to-read fonts in several applications.
Microsoft added a new option to apply one scaling level for all connected displays within the screen resolution settings. However, the option is disabled by default, and is the culprit behind the problem.
To fix the problem:
1. Access “Control Panel” by right-clicking on the Start Button and then selecting “Control Panel” from the menu that appears.
2. Select the “Adjust screen resolution” link under “Appearance and Personalization.” Or, right-click on your Desktop and then left-click to select “Screen Resolution” from the menu.
3. In the “Screen Resolution” dialog box, click the “Make text and other items larger or smaller” link.
4. Next, in the “Display” dialog box, click to select (and enable) the “Let me choose one scaling level for all my displays” checkbox.
5. Click the “Apply” button.
6. Re-start the computer.
