The Eco Capture HDMI 4K M.2 is a single-channel HDMI capture card in the compact M.2 (PCIe 2.0) form factor, built for compact and thin-form-factor PCs — including tablet computers and other small-form-factor systems — where full-size PCIe slots are at a minimum. It captures HDMI input up to DCI 4K 4096×2160 resolution with embedded audio straight to the host computer. The card uses a native JST SHD input connector, supplied with a matching SHD-to-HDMI Type A adapter cable, and is rated for 24/7 operation, with an LED indicator showing input state — idle, signal locked, memory failure, or FPGA configuration. Processing on board includes resolution scaling, timestamping, and a high-fidelity pipeline, with support for a range of output colour spaces. It's compatible with Windows and Linux operating systems.
