The NVIDIA® GeForce® 8 Series graphics card supports HDMI with audio integration solution. With a DVI-to-HDMI adapter and an extra signal cord through the bracket, audio source from sound card(S/PDIF) can be integrated into HDMI interface by simply plugging the cord into the pinhead located on graphics card. Only 1 single HDMI cable is required while streaming audio/video data to flat-panel display devices, such as Plasma/LCD TVs, or projector.
