StarTech PEXHDCAP4K 4K 60Hz HDMI Video Capture Card PCIe x4 HDMI 2.0 Ultra HD

Overview :

The StarTech PEXHDCAP4K is a high-performance internal video capture card designed to record or stream high-definition content from HDMI sources. It is utilized by content creators, live streamers, medical imaging professionals, and software developers who require a low-latency, high-bandwidth solution for capturing 4K video directly to a desktop computer.

Technically, the card utilizes a PCIe x4 interface to provide the necessary bandwidth for uncompressed 4K video at 60Hz. It features an HDMI 2.0 input and an HDMI 2.0 “pass-through” port, allowing users to monitor their video source on a dedicated display in real-time with zero lag while capturing. The card supports High Dynamic Range (HDR10) and 4:4:4 chroma subsampling, ensuring that the captured footage maintains professional-grade color accuracy and contrast. It is compatible with DirectShow and Wave technology, making it natively supported by popular broadcasting software like OBS (Open Broadcaster Software), vMix, and Wirecast.

Deployment is straightforward for desktop users, as the card fits into any available PCIe x4 (or higher) slot. It includes a full-profile bracket for standard towers. The hardware-level video processing helps reduce CPU load during the capture process, which is critical for maintaining system stability during high-resolution gaming or complex live productions. The card also supports high-definition 2-channel digital audio, ensuring the sound quality matches the visual fidelity.
