I've just seen that there is HiDPI support for Windows in IDEA 13.1 :
Support Windows/Linux HiDPI devices via -Dis.hidpi=true
What does this mean exactly ? How can I enable it ? Where should I set this flag ?
I have a high resolution monitor and having higher DPI fonts would be nice, will this setting help with that ? If yes, how can I take advantage of that ?
I've discovered that using checking "Disable display scaling on high DPI settings" in compatibility tab of the Intellij executable or shortcut does the job! I had to reinstall from scratch before it worked.
