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
- — USB 3.2 Gen 2 (USB-C) keeps it external and PC-and-Mac friendly
- — On-device HDR-to-SDR tonemapping simplifies recording for non-HDR workflows
- — HDR10 capture is Windows-only
- — Can be temperamental with third-party HDMI cables
