title: How to programatically change the output mode of an intel gma450 graphics card to clone
body: <p>I would like to change the output mode of an Intel GMA450 based graphics chip to "cloned" mode. </p>
  
  <p>Since the environment is a Windows Embedded Standard and only one of the connected monitors might be visible for the enduser, I would like to either <em>permanently</em> set the output mode to cloned or <em>reset it continuously</em> to cloned mode in case the actual mode differs (e.g. after a reboot, disconect/reconect of the second monitor or by other means).</p>
  
  <p>Is there a way (Registrykey, API for the Intel driver, Win-Api) to change the display mode to cloned / dual output programatically?</p>
  
  <p><em>Update:</em>
  I found the SDK for the IEDG driver it seems that I might be able to programatically set the resolution, clone mode etc. 
  However, I can't find the SDK or any information for the driver I am currently using: Intel® Graphics Media Accelerator Driver for Windows* XP, version 14.32.4.4926.</p>
