title: Qt: How to use AA_UseHighDpiPixmaps for two monitors
body: <p>I'm using two monitors: Retina and Normal.</p>
  <p>I read this article <a href="http://blog.qt.io/blog/2013/04/25/retina-display-support-for-mac-os-ios-and-x11/" rel="noreferrer">http://blog.qt.io/blog/2013/04/25/retina-display-support-for-mac-os-ios-and-x11/</a></p>
  <p>There are:</p>
  <blockquote>
  <p>QIcon::pixmap() has been modified to return a larger pixmap on high-dpi systems. This is a behavior change and can break existing code, so it’s controlled by the AA_UseHighDpiPixmaps application attribute:</p>
  <p>qApp-&gt;setAttribute(Qt::AA_UseHighDpiPixmaps);</p>
  </blockquote>
  <p>When I set this attribute and run program with one of main monitors, all images look normal.</p>
  <p>But if two monitors are active: images in normal monitor look terrible. Qt selects @2x images for normal monitor and resizes their.</p>
  <p>How to solve my problem with two monitors?</p>
