DVI vs HDMI
DVI and HDMI both transmit digital video using the same underlying TMDS signaling, so at the same resolution they deliver an identical picture. The differences are features, not quality: HDMI also carries audio, supports 4K/8K and consumer features (CEC, ARC/eARC), and uses a compact connector, while DVI is video-only but can also carry analog video (on DVI-A and DVI-I) for backward compatibility with VGA. Because both use TMDS, a digital DVI source connects to an HDMI display with a simple passive adapter (video only).
DVI (Digital Visual Interface) arrived in 1999 from the Digital Display Working Group, and HDMI (High-Definition Multimedia Interface) followed in 2002. HDMI was built on the same digital video foundation as DVI, which is why the two are electrically compatible and why a DVI-to-HDMI cable needs no active electronics. The practical question is rarely “which looks better” — it is which one fits your devices and whether you need audio.

What is DVI?
DVI is a video interface designed to carry a pure digital signal from a PC or video source to a display. It comes in three forms: DVI-D (digital only), DVI-A (analog only), and DVI-I (both digital and analog in one connector). DVI-D and DVI-I are further split into single link and dual link; dual link adds a second TMDS link to reach the highest resolutions such as 2560×1600. Critically, DVI carries no audio.
What is HDMI?
HDMI is the standard interface for consumer audio/video. It carries uncompressed digital video and multi-channel digital audio over a single compact cable, and adds features such as CEC (one-remote control), ARC/eARC (audio sent back from a TV to a receiver), and — from HDMI 2.1 — 4K at 120 Hz, 8K, Variable Refresh Rate, and Auto Low Latency Mode for gaming. Each HDMI version raised the bandwidth ceiling, which is what unlocks higher resolutions and refresh rates.
Resolution and bandwidth by standard
Both interfaces are bandwidth-limited, so the maximum resolution depends on the specific standard:
| Standard | Max bandwidth | Max resolution |
|---|---|---|
| DVI single link | 3.96 Gbps | 1920×1200 @ 60 Hz |
| DVI dual link | 7.92 Gbps | 2560×1600 @ 60 Hz |
| HDMI 1.4 | 10.2 Gbps | 4K @ 30 Hz |
| HDMI 2.0 | 18 Gbps | 4K @ 60 Hz |
| HDMI 2.1 | 48 Gbps | 8K @ 60 Hz / 4K @ 120 Hz |
Can you connect DVI to HDMI?
Yes. Because digital DVI (DVI-D and DVI-I) and HDMI share TMDS signaling, a passive DVI-to-HDMI cable or adapter connects them and carries the video with no quality loss. Two caveats trip people up:
- No audio over DVI. A DVI-to-HDMI link passes the picture but not sound — add a separate audio connection.
- HDCP must match. For protected 4K content, every device in the chain (including the adapter) must support the same HDCP revision, or the screen stays blank.
- DVI-A can't go to HDMI. The analog-only DVI-A has no digital signal, so it needs an active converter, not a passive adapter.
For a full breakdown of which connectors work together, see the Connector Compatibility Matrix or try the Cable Selector Guide.
Which should you use?
- Connecting a TV, sound bar, or anything needing audio: use HDMI.
- 4K, 8K, HDR, or high-refresh gaming: use HDMI (2.0 for 4K60, 2.1 for 4K120/8K).
- An older PC or monitor with only DVI: DVI is fine for the picture; use dual link for resolutions above 1920×1200.
- Mixed devices (DVI on one end, HDMI on the other): a passive DVI-to-HDMI cable works for video; handle audio separately.

DVI vs HDMI: frequently asked questions
What is the difference between DVI and HDMI?
HDMI carries digital video plus audio and consumer-control features (CEC, ARC) over a compact 19-pin connector. DVI carries video only and, in its DVI-A and DVI-I forms, can also carry analog video for backward compatibility with VGA. Because both digital interfaces use the same TMDS signaling, a digital DVI source and an HDMI display are electrically compatible and connect with a simple passive adapter (video only).
Is HDMI better than DVI?
For most modern setups, yes — HDMI carries audio and video on a single cable, supports 4K and 8K, and adds consumer features such as CEC and ARC. For digital video alone, the image quality is identical because both interfaces use TMDS signaling. Dual-link DVI can still be useful for high-refresh 1080p or 1440p on older PCs and monitors that lack HDMI.
Is there a picture-quality difference between DVI and HDMI?
No. At the same resolution and refresh rate, digital DVI and HDMI produce an identical image because they use the same TMDS digital signaling. The real differences are features — audio, 4K/8K support, CEC/ARC — not picture quality.
Does DVI carry audio?
No. DVI is a video-only interface, so a DVI connection — or a DVI-to-HDMI adapter — does not pass sound, and you will need a separate audio cable. HDMI, by contrast, carries multi-channel digital audio and video together over one cable.
Can I connect DVI to HDMI?
Yes. Because digital DVI (DVI-D and DVI-I) and HDMI both use TMDS signaling, a passive DVI-to-HDMI cable or adapter connects them and carries the video. Audio is not included over the DVI side, and the analog-only DVI-A cannot connect to HDMI without an active converter.
Is DVI or HDMI better for gaming?
HDMI is the better all-round choice. HDMI 2.1 supports 4K at 120 Hz, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM). Dual-link DVI can still drive 1080p or 1440p at high refresh rates on older monitors, but it has no audio, no VRR, and no 4K support.
