- 1). Check the number of cables you need. HDMI requires a single video cable, while component video cables have three connections. This opens your connection to more possible problems, because if one of the cables is damaged, the entire video signal is going to be affected.
- 2). Determine if you want to purchase additional audio cables. HDMI sends both HD audio and video signals, while component only provides video. You must add in two RCA audio cables into the mix, bringing the total cable connection up to five.
- 3). Check if you have all your HD equipment hooked up. While HDMI only supports HD equipment, component video provides a signal for both HD and SD video content, allowing you to use component video cables on more devices.
