HDMI (High-Definition Multimedia Interface) is a new digital audio and video cable used to connect some TVs, cable boxes and video game systems. HDMI enables a simple and high quality video connection between your video equipment, including your new Lifestyle® system and your digital television.

Simplay HD™ testing assures HDMI compatibility. Some devices featuring HDMI may not work well with others. Many manufacturers submit HDMI devices to Simplay, an independent certifying organization, which conducts tests to assure the compatibility of the electronics products with HDMI. All certified devices carry the Simplay HD label. Bose has submitted these Lifestyle® products to Simplay, which has verified consistent performance between these and all HDMI-enabled devices. These Lifestyle® products have met the standards necessary to bear the Simplay HD label.

Component video is an alternative to HDMI video. Should you experience an issue with HDMI, it may be due to the use of additional devices or components that have not passed Simplay HD™ HDMI compatibility testing. Symptoms may include loss of picture on your television (e.g., no signal, persistent snow, etc.). Fortunately, most HDMI-enabled products also feature component video outputs, which are a high-definition alternative to HDMI video. If you experience a problem with an external video source (e.g., cable box) while using an HDMI connection, we recommend that you use a component video cable and a separate digital audio cable to connect that source to your Lifestyle® system. (See Bose owner's manual for details.) With this simple change, you may enjoy the high performance of most high-definition sources while avoiding HDMI incompatibility issues.If you need further assistance, please contact our technical support group at (852) 2123 9000.
