Magewell Pro Capture Dual DVI

Magewell Pro Capture Dual DVI: Two Independent DVI Capture Channels

The Magewell Pro Capture Dual DVI provides two independent DVI capture channels on a single low-profile x4 PCIe card. At £493, it is a specialist card for environments where two simultaneous DVI sources need to be captured without signal conversion, without the complexity of two separate cards, and without consuming two PCIe slots in a machine that may not have them to spare.

Independent Processing Per Channel

Each channel has its own dedicated FPGA processor. Both inputs operate independently: different resolutions, different refresh rates, different DVI signal characteristics, all without one channel affecting the other. This matters in monitoring and recording environments where the two DVI sources may be fundamentally different types of equipment, each outputting different resolutions and timings that need to be handled as entirely separate capture streams. Both channels accept DVI-D and DVI-I connectors, covering the full range of digital DVI signals from single-link and dual-link sources. Maximum input resolution per channel is 2048x2160.

When Two DVI Channels Are the Right Solution

The buyers for the Dual DVI are working in environments where two simultaneous DVI captures are a genuine operational requirement. This is not a common general-purpose card, but for the workflows it targets, it is exactly the right tool:

• Dual-monitor workstation recording where both screens of a multi-display system need to be captured simultaneously for training, compliance, procedural documentation, or regulated audit trail purposes
• Medical imaging environments with two connected diagnostic displays or two separate imaging devices requiring simultaneous capture and storage
• Digital signage quality assurance with two independent players or displays that need to be monitored and verified simultaneously from a single capture machine
• KVM and remote desktop environments where two independent operator sessions need to be recorded concurrently for compliance or supervision purposes
• Hardware and display controller QA testing where two DVI outputs need to be captured simultaneously to verify synchronisation, timing accuracy, or content matching between channels

Slot Economy and System Qualification

Fitting two DVI capture channels into one x4 PCIe slot is the primary engineering advantage of this card. In regulated environments such as medical facilities or industrial control rooms, minimising the number of cards in a validated system reduces the complexity of system qualification and re-qualification after changes. In compact rackmount deployments, occupying one PCIe slot instead of two may be the difference between a system design that fits and one that does not. A single card also simplifies driver management and reduces potential conflict points in complex software environments.

Software and OS Compatibility

Both channels appear as independent capture devices in production and recording software. vMix, Wirecast, OBS Studio, Adobe Premiere Pro, and FFmpeg all handle both channels as separate inputs, each independently configurable. For compliance recording and documentation workflows, Magewell Capture Express can record both channels independently without requiring a third-party software installation, which is useful in controlled environments where software qualification is a consideration.

The card supports Windows 10, 11, and Windows Server (Magewell driver required), Linux 3.x and later via V4L2 without an additional driver, and macOS 10.14 and later via the MWCapture SDK. It is rated for 24/7 continuous operation, making it appropriate for permanent monitoring and recording installations rather than occasional production use.

Single versus Dual: Choosing Correctly

The Pro Capture DVI at £246 is the right purchase if one DVI channel is genuinely sufficient. The Dual DVI at £493 is for workflows that need two simultaneous DVI captures. If there is a realistic possibility a second channel will be needed in the near future, the Dual DVI is the more practical choice now: adding a second card later requires an additional PCIe slot and bracket that may not be available in your chassis. If two channels are definitively not required, the single-channel card is more cost-effective and uses a smaller x1 slot.
