[Spec disputes (the group's biggest gripe)]

[Positive experiences (both sides of the same user's review, Allen Lee Xbox)]

• Note how it is used: 4K HDR only runs at 30hz + p010 + frame interpolation up to 60 — accept 30-frame HDR and this is the experience you get

[Q&A] ("almost no latency, very satisfying", thanks to frame interpolation); want 2K60 HDR (NS2) → "basically perfect". Q Price reference: 1900 (purchase price at the end of last month) / 2200 (quoted price)

[Conclusion] A card aimed at streaming; gaming/capture users should choose carefully; when the two camps' claims conflict, go by the "capture spec sheet"

════════════════ 3. GC551 / GC551G2 / GC550 ════════════════

• Audio problem (ハスタンの月色): "the built-in video either freezes or there's still no sound" → troubleshooting: select the capture card in both Windows and the software; "the software has taken over the capture card, so obs can't capture anymore" (a capture card can only be occupied by one program at a time)

the capture card picture?" → the author replied "other AMD card users report it's normal" (handle it as an individual AMD card case: send the logs for troubleshooting) [GC550] platinum's experience: "1080 is normal, at 2K only around 40 frames"; it was later confirmed that the bottleneck was software rendering rather than the capture card ("it's not a capture card problem") → when the 2K frame rate won't go up, first lower the rendering load inside Veyra

════════════════ 4. Overall buying advice ════════════════

• For 2K60 needs: a GC553G2 is enough; or the Kuhaomi 27P / Michensen T800 (half the price, 10-15ms)

• General rule of thumb: before buying any AVerMedia model, first go through the "capture format table" (resolution × format × frame rate × HDR) item by item — "check it clearly before you buy" (Aitor); "the passthrough specs are useless to us" (the author) ================================================================

This update and expansion (2026-10-06 – 11-05)

Filtered out of the records of 7 chat groups from 2026-10-06 – 11-05: 39 relevant remarks in total, with the speaker and the date kept.

• An old model, 1080P60, for historical reference only.

Fixes and reminders

• It may be that my capture card is simply too old — you can't even download drivers for the gc550 from the Chinese official site (南方北影像-南翔 10-27)

Group members' own words

"Back when I had the gc550 I played Battlefield nonstop at 1080p and couldn't feel that little bit of latency at all hhh [旺柴]"

Additional notes

• An old model (GC550), 1080P60 capture; only nostalgic discussion is left in the group, a hundred or so second-hand.
• The reference-design MS2130s card at the same price has 40-50ms latency and is actually more worth buying (see the "Other Brands and Low-Cost Cards" page).
