What Is the Difference Between DVI and HDMI?

Short answer

DVI carries video only, while HDMI carries both uncompressed video and audio in a single cable. Both use the same underlying digital signal technology (TMDS), so a passive adapter can convert between them for video — but audio will never pass through DVI.

Works if

  • You use DVI-D Dual-Link for resolutions up to 2560×1600 or 1080p at 144Hz
  • You use HDMI 2.0+ for 4K@60Hz, HDR, and multi-channel audio
  • You use an HDMI-to-DVI adapter for video when ports don’t match
Will not work if

  • You need audio through a DVI cable — it is video-only
  • You need 4K output from DVI — it maxes out at 2560×1600
  • You expect HDR or 12-bit color depth over DVI — not supported

How what is the difference between dvi and hdmi? works and when it fails

DVI vs HDMI: The Core Difference

DVI was designed for monitors and carries video only. HDMI was designed for home theater and consumer electronics, so it bundles video, audio, and control signals in one slim cable. If you plug a source into a DVI port, you will need a separate audio cable to your speakers or monitor.

Both standards use Transition Minimized Differential Signaling (TMDS) for digital video, which is why a simple passive adapter moves video between them with no quality loss.

Audio: The Biggest Practical Difference

DVI has no audio pins. If your monitor has speakers or you are connecting to an AV receiver, DVI forces you to run a separate 3.5mm or optical audio cable. HDMI handles up to 32 channels of audio including Dolby Atmos and DTS:X in a single connector.

For desktop PC gaming on an older monitor, this rarely matters. For a TV, soundbar, or AV receiver setup, HDMI is the clear choice.

Adapters and Compatibility

Because both use TMDS, a passive HDMI-to-DVI adapter works reliably for video. No active electronics are needed. Keep these limits in mind:

  • Audio will not pass through — HDMI audio is dropped at the adapter
  • HDCP 2.2 content (4K streaming) may not pass over DVI at all
  • DVI connectors are bulkier and use thumbscrews; plan for the extra space

If your GPU has HDMI but your monitor only has DVI, an adapter covers you for video. For the reverse, the same applies. Learn more about modern video output options in our guide on whether USB-C can connect to HDMI.

The VESA standards page covers the full DVI specification if you need the technical detail.

Color depth is another gap: DVI tops out at 8-bit per channel, while HDMI supports up to 12-bit, which matters for HDR workflows. If you are working with HDR content, check our article on HDMI cable versions and what they support.

Bottom line: Choose DVI if you have a legacy PC monitor and need high refresh rates at 1080p or 1440p and do not need audio through the cable. Choose HDMI for anything involving a TV, audio passthrough, 4K, or HDR — it is the more capable and future-proof connection in almost every scenario.
