However, it is being included on all newer Macs and many Dell, HP, and Lenovo computers. It was designed as the successor to DVI and VGA on computers, but hasn’t seen as much adoption as either DVI or HDMI. For almost all purposes, a single HDMI cable is all you’ll need to connect your computer or video device to your monitor or TV, and it’s almost the absolute standard digital cable.ĭisplayPort is another new video connector that’s being included on newer equipment, especially laptops. They also support HDCP encryption for the newest HD content. HDMI cables support up to 1920×1200 HD video and 8 channel audio. HDMI cables can stream digital video and audio simultaneously over the same cable. HDMI cables and ports are very easy to use, and are almost as easy to connect as USB devices. HDMI is the default cable on newer HDTVs, Blu-ray players, Apple TV, many new computers and video cards, and a multitude of other video devices. You can also connect an older monitor that only includes a VGA port with a DVI port easily via a similar DVI to VGA converter if your video output supports analog video. It’s both backwards and forward compatible, though at the loss of some convenience. However, since DVI doesn’t support audio, you’ll need to use a separate cable for audio when connecting to an HDMI port.This makes DVI one of the more versatile newer connectors. You can connect DVI to an HDMI port on a newer monitor with a small digital convertor.

The biggest problem with DVI is that it doesn’t support HDCP encryption by default, so if your hardware only includes DVI ports, you may not be able to playback full HD Blu-rays and other HD content.ĭVI to HDMI convertor image via Wikipedia If your port contains all the pins, however, it can support the max resolution with no problem. Some DVI cables or ports may include fewer pins if they are designed for lower resolution devices, so you’ll need to watch for this. DVI can stream up to 1920×1200 HD video, or with dual-link DVI connectors you can support up to 2560×1600 pixels. It’s the most similar to VGA connectors, with up to 24 pins and support for analog as well as digital video.

Confused yet? Here’s how to know which is which:ĭVI is one of the most common digital video cables you’ll see on desktops and LCD monitors today. DisplayPort is another newer connector that’s being included on some newer computers, and there are also several mini and micro variants of all three. The two main digital connectors used on computers and entertainment systems today are HDMI and DVI. What’s the Difference Between Digital Cables? Even if your current computer and monitor work fine with VGA cables, you’ll still want to know which digital cable is best for future video equipment purchases. Some video cards and video playback devices, including the new Apple TV, don’t even include VGA or composite outputs, and this will be an increasing trend looking forward. While many current LCD TVs and computer monitors still accept VGA input, they generally work best with DVI or HDMI. While this works great for CRT screens, it isn’t preferable for newer LCD screens. The traditional video cables, including VGA and Composite video, transmit analog video signals only. Why not VGA or Composite Video Cable?ĭIY Component to VGA Adapter via Balazs H on Flickr If you want to get the entertainment off your files and disks and onto your screen, cables are a necessary evil for the time being.
In general, they all work the same: the connector contains pins that go into ports on your video output device which transmit video, audio, and more over the wires in the middle. For now, we’re stuck streaming our media through wires. While there’s been some progress in this area, frankly it’s not a viable solution for most today.

We’d all love it if you could just zip your video and audio over the air from your devices to your screens.
