Key takeaways
- Connection type: PCIe cards like the AVerMedia GC570D deliver the lowest latency and highest bandwidth for a dedicated streaming PC, while USB 3.0 cards offer flexibility if you swap machines or travel with your setup.
- Pass-through resolution: Ensure the card supports at least 4K60 pass-through so your gaming PC monitor receives an uncompressed signal while the streaming PC encodes separately.
- Capture resolution and frame rate: For most Twitch and YouTube streams, 1080p60 capture is the sweet spot; 4K30 or 4K60 recording matters mainly if you archive high-resolution VODs.
- Latency: In a dual PC workflow every millisecond counts. Look for cards advertising sub-frame or ultra-low latency, especially if you monitor your stream on the capture machine.
- Software compatibility: Confirm the card works natively with OBS, Streamlabs, or your preferred encoder on Windows 11 (or macOS) without proprietary driver headaches.

Choosing the right capture card for a dual PC setup is confusing: you need to balance pass-through resolution, latency, connection type (PCIe vs. USB), and whether you are capturing a second PC, a console, or a camera. This guide cuts through the noise with five tested picks, a side-by-side comparison, and buying criteria specific to two-machine streaming rigs so you can match the right card to your exact workflow.

The Best HDMI Capture Cards for Dual PC Streaming Setupss Reviewed
Best Overall: AVerMedia Live Gamer Duo (GC570D)
With two HDMI inputs on a single PCIe card, the Live Gamer Duo lets you capture both a gaming PC and a console or camera simultaneously without occupying a second slot. It is the clear choice for streamers who want 4K60 HDR pass-through to their monitor while encoding 1080p240 on the streaming rig.
Best Budget: 4K HDMI Video Capture Card (USB 3.0)
This no-frills USB 3.0 dongle delivers reliable 1080p60 capture for under twenty dollars, making it ideal for first-time dual PC builders who want to test the workflow before investing in pricier hardware. It pairs seamlessly with OBS and works across Xbox, PS5, and PC sources.
Best Premium: Elgato Cam Link 4K
Elgato’s Cam Link 4K combines ultra-low-latency HDMI-to-USB capture with rock-solid driver support on PC, Mac, and even iPad. Streamers who also use a DSLR or action cam as a face-cam will appreciate the single-device flexibility, and the 4K60 input ensures zero quality loss from a high-end gaming PC.
Best for Console Streaming: XIIXMASK Video Capture Card
The XIIXMASK card’s 4K HDMI loop-out means your PS5 or Switch feeds a lag-free signal straight to your TV while the capture path records at 1080p60 or 2K30 to the streaming PC. It is a smart pick for console-first streamers who still want a dedicated encoding machine.
Best for Portable Setups: acer USB 3.0 HDMI Capture Card
Acer’s capture card ships with both USB Type-A and Type-C cables, making it easy to move between a desktop streaming PC and a laptop on the go. The 4K loop-out and low-latency audio path keep the experience smooth whether you are at a desk or streaming from a LAN event.
Frequently Asked Questions
Do I really need two PCs to use these capture cards?
No. Every card here also works with a single PC, a console, or a camera. However, a dual PC setup offloads encoding from your gaming machine, which is where these cards deliver the biggest performance benefit.
Is a PCIe card always better than USB for dual PC streaming?
PCIe cards generally offer lower latency and higher sustained bandwidth, but a quality USB 3.0 card like the Elgato Cam Link 4K is indistinguishable in a 1080p60 stream and far easier to install.
Will a 4K pass-through card still work if my monitor is only 1080p?
Yes. The pass-through simply mirrors whatever resolution your GPU outputs. A 4K-capable card future-proofs your setup without forcing you to upgrade your display immediately.
Can I capture audio from my gaming PC through these cards?
All five picks carry embedded HDMI audio. In OBS, add the capture device as an audio input source, and game sound, mic audio routed through the PC, and console chat will come through the same cable.
Final Thoughts
For a serious dual PC streaming build, the AVerMedia Live Gamer Duo is the card to beat with its dual HDMI inputs and 4K60 HDR pass-through. If budget is the priority, the 4K HDMI Video Capture Card (USB 3.0) gets you streaming for pocket change. And if you want the lowest possible latency in a compact USB form factor, the Elgato Cam Link 4K remains the gold standard. Pick the card that matches your connection preference and resolution needs, pair it with OBS on your streaming rig, and you will be live in under an hour.
