title: Why is Screen returning a lower resolution than my Windows 8 tablet is set to?
body: <p>I've got a Windows 8 tablet with a Full HD resolution of 1920x1080 pixel set.</p>
  
  <p>But when I use Delphi's <code>Screen</code> object to get the <code>Screen.Width</code> and <code>Screen.Height</code> it will return a resolution of 1280x720 running on that Windows 8 tablet.</p>
  
  <p>Where is the problem rooted? On the Windows (tablet) side or on the Delphi side? I use Delphi 7 up to XE2 with equal results. This seems to be rather a tablet problem than a general Windows 8 problem since I do not have such a behavior on my Windows 8.1 desktop machine.</p>

  <p><em>Conclusion</em></p>
  
  <p><em>I just wanted to highlight the cause of my problem since it is kind of hidden in the comments.<br>
  By default Windows 8 on my tablet is using 150% DPI. 1080px are 150% of 720px. So 720px are usable by applications. Decreasing the DPI percentage to 100% results in the expected 1080px resolution.</em> </p>
