title: How to find if HD is supported by iPad or not
body: <p>I am getting in trouble of finding the HD support in iPad. 
  Is there any way to find out that HD playback is supported by the iPad or not programmatically.</p>
  
  <p>I read somewhere that HD playback is only supported by retina Display.But later i found that iPad 2 without a retina display is also able to play the HD videos..</p>
  
  <p>So is there any other way to find whether the HD playback is supported or not as it seems like it doesn't relates to Retina display at all.</p>
