  • Hello @Erwan,

    Your projector may be recognized by the DualHead, but what's important, is that the DualHead need to be recognized by the computer : so be sure you see the DualHead in System Preferences / Monitors.
    Also, be sure your adaptor to convert DP to HDMI is valid. You may have to
    contact Matrox support, to know if specific adaptors are required to
    convert DP to HDMI.

    Best. Philippe
  • Merci Philippe. 
    Je pense qu'en fait c'est le vidéo projecteur qui ne reconnait pas le signal. j'ai pu connecter ma configuration sur un autre écran sans problème.
