Blackmagic Design DeckLink Quad HDMI Recorder – PCIe 擷取卡（B-Stock）

Caught this as an ex-demo and honestly wasn't sure what to expect, but it's been flawless so far. All four HDMI inputs recognized instantly on my system and the card runs cool even after a few hours of capture. Considering it's used, you'd never know it wasn't brand new.

For an open-box unit this card looks practically brand new. I've got it feeding four separate camera feeds into my live stream setup and the latency feels nonexistent.

Got the b-stock unit and you honestly can’t tell it was a demo — all four HDMI inputs lock onto signal instantly, no dropped frames during a two-hour multicam recording session. The card runs surprisingly cool even with all channels active, which is a relief for my cramped workstation.
