A final note, make sure you adjust your display resolution to the native resolution of your TV. Most TV’s are 720p or 1080p, which in computer resolution terms are 1280x720 or 1920x1080, respectively. This will ensure the highest quality picture for you and your family.

DMI has quickly become a popular request for users who read about all the features it brings - most notably its ability to carry both audio and video over a single cable. Since most older systems do not include an HDMI port, the first step needed will be to upgrade your graphics card to a new one that does. For graphics solutions there are two players: Nvidia and ATI. Both manufacturers produce video cards with HDMI ports (or DVI ports with HDMI adapters), but Nvidia does not have it’s own sound chip on board. What that means is that the Nvidia is merely a pass-through of the S/PDIF audio. If you only have a 5.1 surround sound setup, then this is acceptable. For users with newer 7.1 surround sound setups, ATI will be the only graphics card of choice. The ATI contains a dedicated sound chip on-board which allows for support of up to 7.1 multichannel audio over the HDMI cable.
The other critical piece of information necessary is to ensure you have an available port on your motherboard to support the video card. You can refer to your motherboard or computer documentation for this information if you do not know. Basically, there are two standards. These are the older AGP connection and the newer PCI-Express. Any computer built in the last 2-3 years should have a PCI-Express slot. If you only have AGP, upgrading may be more difficult as the number of AGP cards with HDMI ports is quite limited and may cost more. If that’s the case, you may be better suited for a complete system overhaul or re-purchase.
