title: HiDPI in IntelliJ 13.1, how to use it? what is it good for?
body: <p>I've just seen that there is <a href="http://confluence.jetbrains.com/display/IDEADEV/IDEA+13.1+EAP">HiDPI support</a> for Windows in IDEA 13.1 :</p>
  
  <blockquote>
    <p>Support Windows/Linux HiDPI devices via -Dis.hidpi=true</p>
  </blockquote>
  
  <p>What does this mean exactly ? How can I enable it ? Where should I set this flag ?</p>
  
  <p>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 ?</p>
