Symptom

Currently, when a PB application is used on a 4K or 8K monitors with Windows DPI greater than 100%, you will see fuzzy fonts. Different monitors and OS DPI settings will result in different display effects.
 

Environment

PowerBuilder 2017 and above
 

Cause

This is due to a difference when an application developed on a low resolution monitor is used on a high resolution monitor with OS DPI setting.
 

Resolution

We suggest that you adopt the following methods to optimize this issue.

1. Change your current application font to a high resolution font.

For example, you can change the default Tahoma font to Segoe UI. Font size 10 or higher is recommended.

2. Add a manifest file and modify the associated settings.

You can choose "External Manifest" in the security tab when generating the exe. At this time, it will generate in the exe folder a file named <applicationame>.exe.manifest. You can add the content below into the generated manifest file:

choose

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">

  <asmv3:application>

    <asmv3:windowsSettings>

      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>

      <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness>

    </asmv3:windowsSettings>

  </asmv3:application>

</assembly>
