The Elgato 4K X is the most capable external capture card you can buy right now, pushing all the way to 4K144 capture with HDR10 and HDMI 2.1 passthrough. Reviewers treat it as the gold standard for serious creators who want headroom beyond 4K60. It costs more than the competition and demands a fast PC, but nothing else in the external class matches its ceiling.
- — Captures up to 4K144 with HDR10, far beyond most external cards
- — HDMI 2.1 in and out with lag-free VRR passthrough for OLED and high-refresh panels
- — USB 3.2 Gen 2 (USB-C) keeps it external and PC-and-Mac friendly
- — Most expensive external card here at around $200
- — 4K144 capture needs serious storage and CPU headroom
- — HDR10 capture is Windows-only
