Computex 2006 Asus showed two graphics cards with HDMI connectors on its stand at Computex this week. The first was an ATI Radeon X1600 Pro-based low-profile card with an HDMI and D-sub connector – a similar design to the ones that Sapphire has shown in the past. However, the second card was based on an Nvidia GeFore 7600GT and featured S/PDIF input.
There have been some concerns about how to enable sound from a graphics card over the HDMI connector, as HDMI also supports a digital audio stream. Asus solved this by adding an optical S/PDIF connector to the rear of the graphics card. An optical S/PDIF cable is then used to connect the graphics card to your sound card’s optical output port. This way the sound is transferred from the sound card to the graphics card and then sent out alongside with the video data.
