Screen resolution 3840x2160

1

Hello DmitryBarashev,
on the new monitor with resolution 3840x2160 the application is not looking good. Something is scaled properly but some texts and other things are not, so the result is a mix of normal and really tiny things.
Do you plan to make some adjustment for higher resolution in next versions of your great app?

Thanks,
Petr

There is DPI option for high-density screens, did you try it? If you did then can you tell us where do you observe tiny things?

Oh, I thought it is for printing only… It looks much better now. But still there are some more things that are not affected by DPI settings.

On printscreens you can see difference between resolution settings:

1920x1080

3840x2160 DPI=96

3840x2160 DPI=200

But as I wrote, it looks much better now and I can work with that.
Thanks a lot,
Petr

Well that was a good try. Still having screen issues for me. When I get it set the way I want, click OK looks good. However when I exit and go back in it doesn’t keep the settings correctly.

Did you change by any chance application font and chart font sizes along with DPI option?

6

I only changed DPI and the change in the screen looked good while I was working. Should I change font size too?

7

No, DPI should be enough. So how your settings look like now? Can you post a screenshot of Application UI page?

Font size: normal
Application base size: normal
DPI: 106.

Thank you for this nice app.

I have resolved the scaling issue in Windows 11 with the following tweak:

Override DPI Scaling in Windows:

  • Locate the GanttProject executable or shortcut.
  • Right-click on it and select Properties.
  • Go to the Compatibility tab.
  • Click Change high DPI settings.
  • Check Override high DPI scaling behavior and set it to System.
  • Apply the changes and restart the app.

Had the same issue on my MacOS 15. I resolved it by manually editing Info.plist. It is not ideal (a bit blurry on Retina display but fine on larger external displays).

Steps to Manually Edit Info.plist:

  1. Locate the GanttProject Application:
  • Open Finder.
  • Navigate to where GanttProject is installed (e.g., in the /Applications folder).
  1. Show Package Contents:
  • Right-click on GanttProject.app and select Show Package Contents.
  • Go to the Contents folder.
  1. Open the Info.plist File:
  • Inside the Contents folder, find the Info.plist file.
  • Open it with a text editor (TextEdit or Xcode).
  1. Change the Value:
  • Locate this line:
<key>NSHighResolutionCapable</key>
  <string>true</string>
  • Replace both lines with:
<key>NSHighResolutionCapable</key>
<false/>
  1. Save the File:
  • Save your changes and close the file.
  1. Restart GanttProject:
  • Relaunch the app and check if the issue is resolved.

Note that this edit might have to be redone if you update the app.
