Elgato 4K X Review – Next-Gen 4K144 Capture and HDMI 2.1 Fidelity for Enthusiast Streamers
When high-performance consoles like the PlayStation 5 and Xbox Series X introduced high-refresh HDMI 2.1 capabilities, standard external capture cards became a bottleneck, forcing players to lower their console settings. The Elgato 4K X removes this limitation entirely, offering a high-speed external design equipped with full HDMI 2.1 support and a fast 10 Gbps data bus.
High-Bandwidth USB 3.2 Gen 2 Performance
The 4K X utilizes a high-speed USB 3.2 Gen 2 Type-C interface operating at 10 Gbps. This fast pipeline enables the card to move uncompressed high-resolution video directly to your computer.
It is also natively compatible with Apple Silicon, making it a reliable solution for MacBook power users who want professional-grade, plug-and-play capture over Thunderbolt or USB4 ports.
4K144 High Frame Rate Capture & Passthrough
Equipped with HDMI 2.1 input and output ports, the 4K X ensures your gaming display remains completely uncompromised. You can enjoy your console games at 4K resolution at 144Hz with smooth Variable Refresh Rate (VRR) and HDR10 enabled.
For archiving and content creation, it records raw video files at up to 4K at 144 FPS or 1440p at 240 FPS, delivering exceptionally fluid video files for your editing timeline.
💡 Production Tip: The 4K X includes a built-in 3.5mm analog audio line-in port. This allows you to feed a physical audio mixer, chat link cable, or secondary microphone directly into the capture device, simplifying your audio routing.
