What are DVI ports?
DVI ports are primarily for connecting your computer to your TV. They aren’t as high quality as HDMI, but most modern DVI are better than VGA. Which DVI cable you can use with the port depends on the number and arrangement of the pin holes in the port.
Why are there so many different types of DVI?
DVI has changed dramatically with evolving technology. The old DVI-A is an analog port no better than VGA. But DVI-D is digital, and DVI-I is compatible with both digital devices and older analog devices.
DVI-D and DVI-I are further broken down by single-link and dual-link capabilities. Dual-link connections have twice as much power, leading to an increase in speed and signal quality.
Which DVI connector is best?
Both DVI-D and DVI-I work fine. Just make sure the pin holes in your port will support the cable type you’ve chosen.
Can DVI cables carry audio too?
DVI-I-to-HDMI or DVI-D-to-HDMI cables can carry audio, but it depends on whether or not the video card inside your computer supports this transfer. Hook in the DVI end into your computer and the HDMI cable into your TV to see if your video card port is compatible with audio. If not, you’ll need a separate audio connection.
