-----------------------------------
Resolution: Fixed
Confirmed fixed in 10.0 release.
> Mark Windows launcher binary as per-monitor DPI aware
> -----------------------------------------------------
>
> Key: NETBEANS-1227
> URL: https://issues.apache.org/jira/browse/NETBEANS-1227
> Project: NetBeans
> Issue Type: Bug
> Components: platform - Launchers&CLI
> Affects Versions: 9.0
> Environment: Windows 8.1 and Windows 10
> Reporter: Eirik Bakke
> Priority: Major
> Labels: HiDPI, pull-request-available
> Fix For: 10.0
>
> Attachments: SmallIconsRun.png

> Time Spent: 2h 20m
> Remaining Estimate: 0h

> As of Java 10.0.2, support for HiDPI monitors on Windows is quite good. All
> the standard Swing components appear in high resolution, and Graphics2D
> surfaces are automatically scaled appropriately for whichever monitor their
> containing window is located on, including when windows are dragged between
> monitors in a mixed-DPI multi-monitor setting.
> For this to work, however, the EXE file that launches NetBeans must contain a
> manifest that declares the application to be DPI-aware. Such a manifest
> currently exists in java.exe and javaw.exe, but not in the custom
> netbeans64.exe launcher. A workaround for the missing manifest is to right
> click the "bin\netbeans64.exe" file, or whichever shortcut is being used to
> open NetBeans, go to the "Compatibility" tab, click "Change high DPI
> settings", "Override high DPI scaling behavior", and select scaling performed
> by "Application".
> An appropriate manifest should be added to netbeans64.exe to declare NetBeans
> as per-monitor DPI aware.
> To see how the manifest should be declared, we can dump the manifest of
> javaw.exe:
> {code:xml}
> <?xml version="1.0"?>
> <assembly xmlns="urn:schemas-microsoft-com:asm.v1"
> xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" manifestVersion="1.0">
> <assemblyIdentity name="javaw.exe" version="10.0.2.0"
> processorArchitecture="X86" type="win32"/>
> <description>Java(TM) SE process</description>
> <!-- More stuff goes here. --->
> <asmv3:application>
> <asmv3:windowsSettings
> xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings";>
> <dpiAware>true/PM</dpiAware>
> </asmv3:windowsSettings>
> </asmv3:application>
> <!-- More stuff goes here. --->
> </assembly>
> {code}
> This reveals that Java 10.0.2 considers itself DPI-aware at the "Per Monitor
> V1" level (see the Microsoft documentation linked below). The NetBeans
> launcher binary should declare the same.
