For streaming Steam Deck OLED through a capture card, the Elgato Game Capture 4K X suits streamers who want the widest passthrough range and HDR capture on Windows, while the AVerMedia Live Gamer Ultra 2.1 suits buyers who want a similar high-refresh setup from a second maker. The original AVerMedia Live Gamer Ultra is the lower-cost route for 4K60 passthrough with 4K30 capture, and the Elgato HD60 X is a previous-generation option for 1080p60 capture. Everything below relies on stated specifications from makers and on independent roundups, and it flags where those sources disagree.
Start with how the Deck reaches the card
The Steam Deck has no HDMI input, so a capture card can only record it if the Deck’s video leaves through an output the card can read. That usually means a dock or adapter with HDMI output, and the sources did not spell out that chain in detail. Check your dock’s manual for its HDMI output and resolution limits before you buy. The card’s own limits matter less than the weakest link in the chain.

Valve has not said when the change reaches the stable client, so treat it as a software option rather than a hardware replacement.
The options compared
The table lists the capture cards that appeared most often in the sources. Figures are as stated by makers and listings, and the notes column records where sources disagree.
| Model | Best for | Stated passthrough | Stated capture | Limits to know |
|---|---|---|---|---|
| Elgato Game Capture 4K X | Widest passthrough range and HDR capture | Lag-free up to 2160p144, 2160p60, 1440p240, 1080p240, with VRR and HDR per the maker’s help page | 2160p144, 2160p30 HDR, 1440p144, 1440p60 HDR, 1080p240 per the maker’s page | HDR capture is Windows only; 4K144 capture is not available with HDR; one retailer lists 4K120 as the capture maximum |
| AVerMedia Live Gamer Ultra 2.1 (GC553G2) | High-refresh passthrough over HDMI 2.1 | Up to 4K144, 1440p240, 1080p360 with HDR and VRR per the maker’s page | Not confirmed in the sources | USB 3.2 Gen 2 Type-C connection; check the model number, since it is easy to confuse with the original |
| AVerMedia Live Gamer Ultra (GC553) | Budget 4K60 passthrough with 4K30 capture | Lag-free 4Kp60 HDR passthrough per the maker’s page | 4Kp30 capture; 1080p60 HDR recording | One retailer listing says 4K and HDR recording work only with NVIDIA graphics cards on the PC |
| Elgato HD60 X (previous generation) | 1080p60 HDR capture on a budget | 4K60 HDR10 passthrough with VRR per listings | 1080p60 HDR10 capture; 4K30 capture in one listing | Listed as discontinued by one retailer; the Elgato explainer names the 4K S as its successor |
Pick the right card for your stream
| Pick this | If you need | Watch for |
|---|---|---|
| Elgato Game Capture 4K X | High-refresh passthrough and HDR capture on Windows | Capture limits drop when HDR is on |
| AVerMedia Live Gamer Ultra 2.1 | HDMI 2.1 passthrough at high refresh from a second maker | Confirm the GC553G2 model number, not the original |
| AVerMedia Live Gamer Ultra (original) | 4K60 passthrough at a lower tier with 4K30 capture | Check the GPU requirement for 4K and HDR recording |
| Elgato HD60 X | 1080p60 HDR capture from a previous-generation card | Discontinued by one retailer; check stock |
Handheld-specific options
One roundup reports a combined capture-card, dock, and charger unit from AVerMedia, the Elite Go GC313Pro, and says the writer used it with a Steam Deck. That is a reviewer’s report, not a maker claim, so check the maker’s compatibility list before buying. A combined unit reduces the cable count, which can help when the Deck sits on a desk. Confirm that the dock’s HDMI output and the unit’s input match your setup.
Connection and PC requirements
Most external cards connect to the PC over USB, and the USB version sets the top bandwidth. The 4K X uses USB 3.2 Gen 2 Type-C, while the original Live Gamer Ultra uses USB 3.1 Type-C, and the older HD60 X connects over USB-C as well. Confirm that your PC has a port of the right type and speed, and use the cable that comes with the card. A USB hub can limit bandwidth, so connect the card directly to the PC where possible.
Decision table: match the card to your stream
| Your stream | Pick | Reason from the sources |
|---|---|---|
| High-refresh Deck output on a Windows PC | Elgato Game Capture 4K X | Stated passthrough to 2160p144 with HDR and VRR |
| HDMI 2.1 passthrough from a second maker | AVerMedia Live Gamer Ultra 2.1 | Stated 4K144 and HDR/VRR passthrough |
| 4K passthrough on a budget | AVerMedia Live Gamer Ultra | Stated 4K60 HDR passthrough with 4K30 capture |
| 1080p streaming with HDR | Elgato HD60 X | 1080p60 HDR10 capture listed |
Alternatives worth comparing
If you do not need HDR or passthrough, a plain 1080p capture card can be enough for a Deck stream, and it may be easier to find in stock. An all-in-one streaming setup that handles capture, switching, and audio can suit a streamer who wants fewer boxes on the desk. A software-only approach is possible for some streams, but it does not replace a capture card when you need to record the handheld’s output directly. Before settling on any option, read the card’s software and firmware update notes on the maker’s support page, since capture software can change how HDR and high-refresh modes behave over time.
Building the streaming chain
Before you buy a card, sketch the full path from the Deck to the stream. The dock you use must provide an HDMI output the card can read, and the resolution and refresh rate set on the Deck have to fit both the dock and the card. On the PC side, the card needs a free port of the right USB type and enough bandwidth for the resolution you plan to capture. In the streaming app, check that your encoder can keep up with the rate the card passes through, since a high-refresh signal does not help if the encoder is set lower.
Audio is the part many streamers overlook. The 4K X lists a 3.5 mm line-in port in its maker’s specifications, which lets you bring in a second audio source alongside the game feed. Decide whether you need game audio, a microphone, or both mixed in your streaming software, and confirm the card’s audio routing before going live. A short test recording shows whether sound and video stay in sync.
Resolution targets should match the platform you stream to and your upload speed. A 1080p60 stream is a common target, and both the HD60 X and the 4K X list 1080p capture that covers it. A 4K capture is useful for recording gameplay for editing, but it produces large files and needs more storage and processing power. Capture settings can be changed in the software, so starting at a lower resolution and moving up once the stream holds steady is a sensible approach.
Frequently Asked Questions
Will a capture card record Steam Deck OLED HDR?
The 4K X lists HDR capture at lower resolutions and frame rates, and the maker says HDR capture is available only on Windows. The original Live Gamer Ultra is listed with HDR passthrough but 1080p60 HDR recording. Check the HDR combinations on the maker’s page for your target stream.
Do I need a dock to capture a Steam Deck?
The Deck needs an HDMI output to reach most capture cards, and the usual route is a dock with HDMI. The sources did not describe every adapter, so check your dock’s HDMI output and resolution before buying a card. Without a usable output, the card has nothing to capture.
Is the 4K X worth the cost over the original Live Gamer Ultra?
The choice depends on whether you need high-refresh passthrough and HDR capture on Windows. The 4K X lists more passthrough options, while the original lists 4K60 passthrough at a lower tier. Compare the stated limits against your stream plan rather than the cost alone.
Does a capture card work with a Mac?
Some cards list macOS support, but HDR capture and some resolutions are often limited to Windows. Check the maker’s operating system list for the exact model. The original Live Gamer Portable line, for example, is listed as incompatible with Apple silicon, so do not assume a card works across platforms.
Will a capture card add delay to my stream?
Makers describe their passthrough as lag-free, which means the screen you see is not delayed by the card. Streaming delay depends on the encoder, your upload speed, and the platform. Test your setup with your own encoder settings before going live.
Is the HDR streaming feature in the Steam client the same as a capture card?
No. The Steam client feature is software, and Valve has not confirmed when it reaches the stable client. A capture card records the Deck’s video output on a PC or streaming setup. The two can be used together, but the client feature does not replace the card.
