Oracle JDeveloper 4K Display (3840×2160) Resolution Problem on Windows 10


When I moved to Dell XPS laptop … YES! It’s absolutely better than Mac-Pro 🙂 

I had a serious problem about JDeveloper user interface on Windows 10 which was a UI scale problem.


  • Oracle JDeveloper (jdev) buttons,icons,menu is too small
  • Fonts are too small.
  • It’s impossible to develop even “Hello World” 🙂


  • Windows 10 (x64)
  • Java 1.7.080
  • JDeveloper 12c (12.1.3) –> Works for other 12c JDeveloper Versions: (12.2.x, 12.1.x)
  • Screen Resoultion: 3840×2160 ( 4K )

First Solution (Up to Date – 2021)

The simple way; Create a shortcut for JDeveloper on desktop then right click on it; Select “Properties” and go to “Compability” tab, find “Change high DPI settings” button at bottom and click on it. Check the option “Override high DPI scaling behavior. Scaling performed by: System”. Finally click OK, click Apply! (Check below screencapture for your reference)
That is it; you are now able to use JDeveloper for your 4K or 2K display. If it is not worked for you try below manual solution. Both worked for me!


Here is the second solution for JDeveloper: (Works for every executable JAVA apps) (Netbeans, Eclipse, JDeveloper, SOAPUI)

Follow below steps to get BEST practice for JDeveloper Screen Quality …Till Oracle Support 4K High Resolution Laptops for JDeveloper 😉

1. Add new registry key to REGEDIT as below:

PATH --> HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide

Select New (Left Click) –> QWORD (64-bit) Value

  • Value Name: PreferExternalManifest
  • Value Data: 1


2. Go to JDeveloper installation path and find “jdev64W.exe” file under $MW_HOME\jdeveloper\jdev\bin folder. (My folder path: D:\oracle\MiddlewareSOA12130qs\jdeveloper\jdev\bin\)

3. Create new text file in this folder and name it exactly as “jdev64W.exe.manifest” by changing its extension. (Reference below picture)


4. Edit “jdev64W.exe.manifest” file content as below and save it.

<?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">
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<requestedExecutionLevel xmlns:ms_asmv3="urn:schemas-microsoft-com:asm.v3"
<asmv3:windowsSettings xmlns="">
<ms_windowsSettings:dpiAware xmlns:ms_windowsSettings="">false</ms_windowsSettings:dpiAware>

5. Edit font sizes:

Go to your $JDEV_USER_DIR\system12.1.3.XXX\o.jdeveloper path and find file. (My path: D:\Oracle\MY_JDEV_USER_DIR\system12.\o.jdeveloper)

Change below font setting parameters from 10 to 14pt. (It’s up to you, but I’ve tested all and I think 14pt is the best ergonomic choice)


6. That’s all. Run JDev by executing “jdev64W.exe” file. (You can create a shortcut on your Desktop)

If you like the solution, please share your thoughts and share the solution with others. Thanks in advance. Keep coding 🙂

    Awesome! Thanks for sharing the knowledge. Keep up the good work.
    It is knowledge like this that developers survive on. I would have changed laptop if not for this article.

    Lenovo Ideapad 14″
    Left the Ide.FontSize=11
    Date: July 20, 2021

    Very sad that I could not find this article in Oracle Support.

  5. I’ve read in that Dimepiece LA celebrity streetwear brand is going to open their second apparel boutique in London. Does anyone know when this is going to happen and where the store will be located? I would totally love to buy the Dimepiece Friends Journal xox

  6. I have searched too much to find solution for this issue but couldnt find. The first solution has worked for me! Thanks Mr. Fevzi. it really helped me!

  7. Half of my team has 4k monitors on their laptops. We have ran into this issue with a lot of desktop clients ( Eclipse, JDev, Oracle Service Cloud’s desktop agent, etc ). This solution has worked on every computer except one of my BA’s. I even made a separate jdev*.exe.manifest file for all the jdev*.exe files in the bin directory but no avail. Very annoying, you think this would be something that would come prepackaged by now

  8. There is a simple way where you can create a short cut of Jdeveloper and right click ,select properties and Under Compatibility Tab and check the option
    ‘Override high DPI scaling behavior. Scaling performed by”: System

      Hi Shurithi,
      This solution sometimes does not work according to hour JDev version. You know; upgrading JDev is not a solution because of Production system SOA versions. Thanks for the contribution

  10. I have the same problem but there is slight change in the configuration w.r.t. to screen resolution is 1920*1080. JDK version is jdk_1.8.0_144. JDev version 12.2.1

    Please help
