DVI comes in three practical connector types: DVI-D (digital only), DVI-A (analog only), and DVI-I (mixed). Single-link supports up to about 1920×1200; dual-link supports higher resolutions (e.g., 2560×1600). DVI-D is digitally compatible with HDMI (video only), while analog VGA needs DVI-A/DVI-I or an active converter. While largely superseded by HDMI and DisplayPort for modern high-resolution and audio/video needs, DVI remains useful for legacy monitors and simple digital links.

What DVI means today

DVI (Digital Visual Interface) defined a generation of video connectors that moved monitors from analog CRTs to flat panels. The DVI family includes three practical connector types you still encounter: DVI-D (digital only), DVI-A (analog only), and DVI-I (integrated digital+analog).

DVI-D vs DVI-A vs DVI-I

  • DVI-D carries only digital video (TMDS signaling). Use it for modern LCDs and flat panels when you want a purely digital path from GPU to display.
  • DVI-A carries only analog video and is functionally similar to VGA. It's rare today but exists for legacy displays.
  • DVI-I includes pins for both digital and analog. It lets passive adapters convert to VGA (analog) or HDMI (digital) where pin compatibility allows.

Single-link and dual-link: why it matters

DVI cables and connectors come in single-link and dual-link variants. Single-link DVI supports typical resolutions up to 1920×1200 at 60 Hz. Dual-link doubles the data channels and supports higher resolutions such as 2560×1600 at 60 Hz. Choose dual-link if you plan to run high-resolution panels that exceed single-link limits.

Practical compatibility and adapters

DVI-D and HDMI share the same digital TMDS signals, so passive adapters (DVI-D ↔ HDMI) commonly work for video. Note that DVI does not carry audio, unlike HDMI. To get sound you'll need a separate audio cable or use HDMI/DisplayPort on the source device.

For VGA (analog) conversions, passive adapters only work if the DVI connector includes analog pins (DVI-A or DVI-I). If your GPU outputs only DVI-D, use an active converter to produce VGA.

Is DVI still relevant?

DVI has been largely superseded by HDMI and DisplayPort for new TVs and monitors, especially for 4K, HDR, and combined audio/video. However, DVI remains useful for older monitors, some desktop GPUs, and simple digital video links where audio and the newest features aren't needed.

Buying advice

  • Inspect the ports on the GPU and monitor before buying a cable. The connector shape and number of pins indicate DVI-D vs DVI-I vs DVI-A and whether it's single- or dual-link.
  • For resolutions above 1920×1200, choose dual-link DVI or move to DisplayPort/HDMI.
  • If you need audio or 4K/120Hz/HDR, prefer HDMI or DisplayPort.
  • For long runs or conversions between standards, consider active adapters or signal extenders.
DVI cables still provide a reliable digital video path for many setups. Know which variant you need and whether an adapter is required to match modern devices.

FAQs about Dvi D Cables

Can I use a DVI cable to get audio?
No. DVI (including DVI-D and DVI-I) carries video only. If you need audio, use HDMI, DisplayPort, or a separate audio connection.
How do I tell single‑link from dual‑link DVI?
Look at the pin array: dual-link DVI has more pins populated in the central block. Product listings usually specify single-link or dual-link; pick dual-link for resolutions above 1920×1200.
Will a DVI to HDMI adapter work?
Yes for video if you're converting digital signals (DVI-D ↔ HDMI). It won't carry audio, and passive adapters won't supply analog VGA unless the DVI port has analog pins (DVI-I/DVI-A).
Is DVI obsolete?
Not entirely. DVI is less common on new TVs and monitors, but it's still useful for older displays, some GPUs, and simple digital video links where audio and advanced features aren't required.
