HDMI tops the list here as the best way to connect your equipment up to your HDTV or HD Projection system.
HDMI provides loss-less video and sound provided you use a Blu-ray disc or other high-definition device. This is important to those that consider themselves audiophiles and have an incredible home theater setup they’re always telling you about. However, even a layman can tell the difference between the HDMI enabled sound and the one run through the standard stereo cable that comes with the component cable.
The fact of the matter is simple – if your TV has HDMI and your equipment has HDMI, there’s no reason the two shouldn’t be meeting through a cable. HDMI provides digital quality and amazing sound, so if your setup has the ability to go HDMI, the cable online is only about $10, and the difference in quality is palpable.
If you’re looking into buying new equipment, you have to make sure that the TV you’re buying has at least one, if not two or three HDMI sockets as this is about a year shy of becoming the standard for HD in your home.
To make matters simpler for you, just follow this guide:
If you have HDMI on both sides of the system, use an HDMI cable
If you don’t have HDMI, but have component connections, use a component cable
If you don’t have either of those two, or just a yellow composite connector, use a composite cable.
