Magewell Eco Capture HDMI 4K Plus M.2

4K60 HDMI Capture with HDR and Loop-Through, from an M.2 Slot

The Magewell Eco Capture HDMI 4K Plus M.2 is the most capable single HDMI card in Magewell's M.2 capture range. It captures a single HDMI source at up to 3840x2160 at 60 frames per second, supports HDR, and includes an HDMI loop-through output, all from an M.2 slot on the motherboard. No PCIe slot required. At £570, it brings the full capability set of a high-end HDMI capture card into compact systems and PCIe-constrained builds where a standard PCIe card is not a physical option.

What the Plus Designation Means

In Magewell's naming convention, Plus on this card indicates three specific capabilities above the standard Eco Capture HDMI 4K M.2:

• 4K60: captures 3840x2160 at 60 frames per second, not the 4K30 of the standard card
• HDR support: handles high dynamic range content accurately from source to production software
• HDMI loop-through output: passes the source signal to a second HDMI output, enabling simultaneous capture and monitoring without an external splitter

Each of these is a meaningful upgrade for the specific workflows that require them.

Loop-Through from an M.2 Card

The loop-through output is notable specifically because this card achieves it in M.2 form factor. A PCIe capture card can route loop-through connections to an output bracket connector in a straightforward way. An M.2 card has no bracket: the physical interface is entirely different. Magewell has implemented a working HDMI loop-through on this card despite that constraint. In compact systems where you need to capture and simultaneously monitor a 4K source without adding an external HDMI splitter, this card is the only M.2 option that makes it possible.

Who This Card Is For

• Production engineers requiring 4K60 HDMI capture in compact systems with M.2 slots but no available PCIe expansion
• Operators who need to monitor a source simultaneously while capturing it, in hardware that cannot accommodate a PCIe capture card
• HDR production workflows that need accurate HDR ingest from compact or embedded hardware
• AV integrators specifying the highest-capability single HDMI M.2 capture card for compact rack or portable deployments

How It Compares to Other M.2 HDMI Options

The Eco Capture HDMI 4K M.2 (£276) captures 4K at 30fps, without HDR, without loop-through. The Eco Capture Dual HDMI M.2 (£276) provides two channels at 1080p60 for buyers who prioritise channel count over resolution. The HDMI 4K Plus M.2 at £570 is the right card when all three capabilities (4K60, HDR, loop-through) are required in M.2 form factor. It is also worth comparing with the Pro Capture HDMI 4K Plus PCIe card (£693): the PCIe card adds a 24/7 broadcast-grade rating and uses a PCIe x4 slot; the M.2 card costs less and installs in an M.2 slot for hardware where PCIe is not available.

Software Compatibility
