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

| December 31, 2016 | 12 Comments

When I moved to Dell XPS 9550 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.

Problems:

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

Environment:

  • Windows 10 (x64)
  • Java 1.7.080
  • JDeveloper 12c (12.1.3) –> Works for other 12c JDeveloper Versions: (12.1.1, 12.1.2, 12.2.1, 12.2.1.1, 12.2.1.2)
  • Screen Resoultion: 3840×2160 (4K)

Here is the 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:

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)

jdev64W.exe.manifest_fevzi_korkutata_jdeveloper_oracle_ace

 

 

 

 

 

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

5. Edit font sizes:

Go to your $JDEV_USER_DIR\system12.1.3.XXX\o.jdeveloper path and find ide.properties file. (My path: D:\Oracle\MY_JDEV_USER_DIR\system12.1.3.0.41.140521.1008\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 :)
