Elgato 4K X (Internal PCIe Gen 4 x4 / 4K144 & 4K120 SDR Capture, 4K60 HDR Capture / 4K144 Passthrough / VRR Capture / HDR Support) Review
The Elgato 4K X is an internal PCIe Gen 4 x4 capture card that performs true high-frame-rate 4K capture: 4K144 and 4K120 in SDR, stepping down to 4K60 only when capturing in HDR. It also passes through 4K144, and captures VRR output from Xbox Series X and PS5.
The specific upgrade for those who want real high-refresh 4K capture, not just pass-through. In SDR it genuinely captures 4K144 and 4K120 — not the 4K60 ceiling many buyers assume from the HDR spec sheet line. Switch to HDR capture and the ceiling drops to 4K60, a real hardware/bandwidth tradeoff, not a marketing quirk. It also captures VRR (Variable Refresh Rate) from Xbox Series X and PS5, making it the only capture card in current comparisons that properly handles modern console output including high-refresh gameplay. A significant upgrade for serious streamers who want actual high-frame-rate 4K captures for archive or YouTube uploads, rather than settling for passthrough-only 4K like more affordable external cards offer. It requires an available PCIe x4 slot in a desktop PC — not compatible with laptops, and setup is significantly more complex than USB capture cards, a real tradeoff for the capture-quality upgrade.
SDR vs. HDR Capture Ceiling — This Card's Key Differentiator
This is the spec most buyers get wrong about the 4K X, and it's the card's actual standout feature: in SDR, it captures true 4K144 and 4K120, not just 4K60. That headroom matters for high-refresh PC gaming capture and for archiving fast-paced 120Hz+ console or PC footage without dropping frames. Switch the source to HDR, though, and the capture ceiling drops to 4K60 — a real hardware/bandwidth limitation of doing full 4K HDR capture, not an arbitrary software cap. In practice: capturing an SDR 144Hz or 120Hz feed gets you the full frame rate; capturing the same source in HDR caps out at 60fps. Passthrough is unaffected either way and stays at 4K144 regardless of SDR or HDR.
True High-Frame-Rate 4K Capture, Not Just Passthrough
Delivers genuine 4K144 and 4K120 SDR capture (with 4K60 as the ceiling only in HDR mode), and captures VRR (Variable Refresh Rate) from Xbox Series X and PS5, making it the only capture card in current comparisons that properly handles modern console output including high-refresh gameplay. A significant upgrade for serious streamers who want actual high-frame-rate 4K captures for archive or YouTube uploads, rather than settling for passthrough-only 4K like more affordable external cards offer.
PCIe Installation Tradeoff
Requires an available PCIe x4 slot in a desktop PC — not compatible with laptops, and setup is significantly more complex than USB capture cards, a real tradeoff for the capture-quality upgrade. 4K144 passthrough handles high-end PC gaming capture and console capture simultaneously.
Comparison to Alternatives
Versus the Elgato HD60 X — that external card only offers 4K passthrough with 1080p60 actual capture, while this 4K X specifically delivers true high-frame-rate 4K capture (4K144/4K120 SDR, 4K60 HDR) for YouTube-quality archival. Versus the AVerMedia Live Gamer 4K 2.1 GC575 — that's a genuine sweet-spot alternative that punches above its price with similar 4K60 HDR capture and HDMI 2.1 for considerably less money, though it doesn't match the 4K X's SDR high-frame-rate capture ceiling.

Expert rating9 / 10
The right step up for creators who need genuine high-frame-rate 4K SDR capture (4K144/4K120) and VRR handling — provided you have a desktop with an open PCIe x4 slot, and you accept the 4K60 ceiling when capturing in HDR.
Best for
- Creators who upload native high-frame-rate 4K to YouTube and need true 4K144/4K120 SDR capture, not just passthrough.
- PCIe desktop builds with an available x4 slot.
- Capturing 120Hz+ console or PC gameplay in SDR without a frame-rate ceiling.
Not for
- Laptop users — requires an open PCIe slot, not compatible with laptops.
- Buyers wanting the simplest possible setup — internal PCIe installation is considerably more complex than USB.
- Anyone who specifically needs high-frame-rate HDR capture above 60fps — HDR capture on this card is capped at 4K60.
