About

AVerMedia's HDMI 2.1 internal capture card — the passthrough loop carries a full 4K144 with VRR intact for the primary display, while the capture engine records a stable 4K60 SDR feed for OBS regardless of what the source is doing upstream.

HDMI version: 2.1
Max resolution: 3840x2160@60Hz
Requires DisplayLink driver: No

Ports: 1× HDMI (entrada), 1× HDMI (salida, passthrough hasta 4K144 con VRR) and 1× PCIe (conexión interna al host)

Confirmed with

PS5
Xbox Series X|S
Routing an Xbox Series X through an HDMI switch (Kinivo 8K) into this card produced "No Signal" — the same switch and card worked fine with a PS5. Connecting the Xbox directly to the card, bypassing the switch, resolved it.
