DVI vs HDMI
Both carry the same digital video signal, but DVI has no audio, no CEC and a bulkier connector. HDMI superseded it.
Last reviewed
HDMI has effectively replaced DVI. The picture quality is the same where both can carry the same resolution, but DVI carries no sound, has no remote-control features, and its connector is a bulky screw-in block. DVI still turns up on older monitors and graphics cards, and it is perfectly usable — a DVI to HDMI adapter is cheap and passive because the video signal underneath is compatible. Just remember you will need a separate cable for audio.
- Verdict:
- HDMI, unless the hardware only offers DVI
Side by side
| Specification | DVI | HDMI |
|---|---|---|
| Audio | No | Yes |
| Max resolution | 2560 × 1600 (dual link) | Up to 8K on 2.1 |
| Connector | Bulky, screw-in | Compact, friction fit |
| Remote control (CEC) | No | Yes |
| Adapts to the other | Yes, passively | Yes, passively |
| Still shipping on new kit | Rarely | Everywhere |
Single link and dual link
A single-link DVI cable manages 1920 × 1200 at 60 Hz. Dual link doubles that to 2560 × 1600 by using more pins. They look nearly identical — count the pins in the large block, because a single-link cable in a dual-link socket simply fails at higher resolutions.
The adapter is passive
DVI-D and HDMI carry the same video signalling, so a plain adapter works with no electronics in it. That is unusual among video standards and worth knowing: you do not need to pay for an active converter here.
Watch for DVI-A and DVI-I
DVI-D is digital only, DVI-A is analogue only, and DVI-I carries both. An adapter to HDMI needs the digital pins, so a DVI-A source will not convert without a real converter.
Getting audio when adapting
A DVI-to-HDMI adapter carries picture only, because the DVI side has no audio pins. Where the display has speakers you want, you will need a separate audio lead, which is the single most common surprise when reusing an older monitor.
Why DVI hung on so long
It was good enough. Until 4K became common, dual-link DVI carried everything a desktop monitor could show, and offices had thousands of cables already installed. Its disappearance owes more to laptops shedding large connectors than to any picture-quality limit.
Identifying the variant
Count the pins and look at the flat blade on one end. DVI-D has no pins around that blade, DVI-I has four, and DVI-A is rare. Only the digital pins convert to HDMI passively, so DVI-I and DVI-D adapt fine and DVI-A does not.
Check before you swap. Batteries with similar dimensions are not always interchangeable. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
DVI vs HDMI: common questions
What is the difference between DVI and HDMI?
HDMI has effectively replaced DVI. The picture quality is the same where both can carry the same resolution, but DVI carries no sound, has no remote-control features, and its connector is a bulky screw-in block.

Which should I choose, DVI or HDMI?
HDMI, unless the hardware only offers DVI. Both carry the same digital video signal, but DVI has no audio, no CEC and a bulkier connector. HDMI superseded it.
Audio — how do they compare?
DVI: No. HDMI: Yes.
