Magewell Pro Capture HDMI 4K Plus LT

4K60 HDMI Capture with HDR: No Loop-Through, Lower Complexity

The Magewell Pro Capture HDMI 4K Plus LT captures a single HDMI channel at up to 3840x2160 at 60 frames per second, with full HDR support, on a low-profile PCIe x4 card. At £693, it sits at the same price as the Pro Capture HDMI 4K Plus but removes the HDMI loop-through output. For buyers who need 4K60 ingest and HDR capability but have no requirement to feed a simultaneous monitoring output from the card itself, the LT delivers identical capture performance without the hardware overhead of the loop-through circuitry.

What It Captures

The Pro Capture HDMI 4K Plus LT accepts HDMI signals up to 3840x2160 at 60fps and handles all standard resolutions at their native frame rates. FPGA processing manages colour space conversion, deinterlacing, and scaling on the card, keeping CPU load low. HDR is supported, covering high dynamic range workflows that require accurate colour and luminance representation from source to production software.

LT: What the Difference Means in Practice

The LT designation indicates one specific difference from the standard Pro Capture HDMI 4K Plus: there is no HDMI loop-through output. In terms of capture performance, resolution support, frame rate, and HDR capability, the two cards are identical at the same price point. The choice between them comes down to one practical question: do you need to simultaneously output the source signal to a monitor directly from the card?

If yes, the Pro Capture HDMI 4K Plus is the right card. If your monitoring is handled separately, via a dedicated output from the source device, an upstream HDMI splitter, or a downstream distribution system, the LT gives you the same 4K60 HDR capture capability in a slightly simpler hardware configuration. There is no capture quality trade-off. The LT is a removal of a feature you do not need, not a reduction in capture performance.

Who This Card Is For

• Broadcast engineers and AV integrators capturing 4K60 HDMI sources where monitoring is handled separately in the signal chain
• Live production teams running dedicated monitoring outputs directly from cameras or signal processors upstream of the capture card
• Post-production facilities ingesting 4K60 HDR content via HDMI with no need for a card-level monitor feed
• Organisations specifying 4K60 HDR capture and managing signal distribution outside the capture card

How It Sits Within the HDMI 4K Range

The Pro Capture HDMI 4K (£385) captures 4K30, has no HDR, and no loop-through: the entry point for 4K HDMI capture. The Pro Capture HDMI 4K Plus LT (£693) steps up to 4K60 and HDR without loop-through. The Pro Capture HDMI 4K Plus (£693) adds loop-through to the same 4K60 HDR capability. The decision between the LT and the standard Plus is purely about whether you need simultaneous monitoring from the card.
