Elgato Game Capture 4K60 Pro: original board, 4K SDR and HDR limits

Windows PCIe, 4K60 SDR capture and 4K60 passthrough

For earlier-inclusive Windows/PCIe OBS with HDMI capture and 4K60 passthrough selected but no HDR-file condition, both the original 4K60 Pro and separate MK.2 remain candidates. On the original, Elgato lists a PCIe 2.0 x4 card, an unencrypted HDMI 2.0 input, 2160p60 capture and HDMI output. The smaller MK.2 is a distinct board; Elgato's OBS path documents tone-mapped SDR output for an HDR input, not an HDR file in OBS. Both model-specific software paths are legacy, so neither guarantees a current driver or app. Read the original 4K60 Pro review before considering that board. Open the finder with exactly these earlier/HDMI/4K60/PCIe/Windows/OBS choices.

This combination is SDR. The model specification lists up to 140 Mbps AVC/H.264 in 4K Capture Utility, but that program cannot stream from this card. Game Capture HD is capped at 1080p60. Do not carry the utility bitrate or stream ceiling from one software path to another.

Adding HDR recording changes the answer

Adding the 4K60 HDR recording condition excludes the original 4K60 Pro but keeps the separate MK.2 only through the Windows Multi App route where 4K Capture Utility records HDR and Stream Link supplies SDR to OBS; OBS does not write the HDR file. This is not a broad “HDR compatible” verdict. Elgato's HDR exchange program ended in 2019, the revision on a used original board may be unclear, and its OBS/XSplit passthrough workaround requires Stream Link. The MK.2 route is likewise legacy and version-dependent, distinct from the original card's hardware and software path. For this exact Windows/PCIe/OBS task, other reviewed-library matches include AVerMedia GC573 and Elgato 4K Pro; compare their own software paths rather than treating HDR labels as interchangeable. Read the separate MK.2 review and its HDR workflow guide; this guide does not certify a used listing.

The original 4K60 Pro review explains the board identity, SDR plan and model-specific limits. Elgato's original-versus-MK.2 comparison supports the name distinction; it does not make the two products one interchangeable configuration. Open the finder with the same setup plus 4K60 HDR recording.

1440p144 is a separate, timing-sensitive route

For a 1440p144 source captured and passed through on Windows PCIe, both the original 4K60 Pro and separate MK.2 remain in the earlier-inclusive candidate set; Elgato warns the high-refresh timing may need a custom or edited EDID. Treat this as a specific mode with a compatibility caveat, not as proof of 4K120, 1080p240 or any other high-rate combination. Confirm the source output, monitor timing, cable, EDID behavior and software on the exact card. Compare the original assessment and MK.2 assessment; the MK.2 workflow guide details firmware and legacy limits. Find candidates for this exact 1440p144 capture-and-display task.
