Yuan SC720N1-L DP1.4a PCIe DisplayPort Video Capture Card with DisplayPort 1.4a Input at 8K30

Capturing the output of a workstation, simulator or graphics system is hard when the source runs at 8K or at 120 fps and the operator still needs to see their own screen. The SC720N1-L DP1.4a is Yuan’s single-channel PCIe DisplayPort video capture card for DisplayPort 1.4a sources, with a loop-through output that keeps the local display running.

The DisplayPort 1.4a input captures up to 7680 x 4320 at 30 or 25 fps, 3840 x 2160 at up to 120 fps, 2560 x 1440 at 144 fps and 1920 x 1080 at up to 240 fps, down to standard SD formats. Color formats cover 4:4:4 8-bit RGB24 and RGB32, 4:2:2 8-bit YUY2, 4:2:0 8-bit YV12 and NV12, and 4:2:0 10-bit P010. One stereo embedded audio channel at 16-bit and 32 to 48 kHz is captured with the video.

The card uses a PCIe x8 Gen2 interface. On-board processing covers cropping and scaling, auto signal detection and a deinterlace engine, and multi-instance and multi-device support lets software open several streams or cards at once. Yuan provides a Windows and Linux SDK and lists vMix, OBS, Zoom, Teams and Cisco Webex among compatible applications, along with DirectShow and V4L2 software. For HDMI 2.1 sources the SC750N1-L HDMI2.1 captures 8K at 60 fps with its own loop-through, and the SC710N2-L HDMI2.0 takes two 4K60 HDMI 2.0 inputs.

Operating system support covers Windows 7, 8, 8.1 and 10, Linux 4.8 or higher in 32-bit and 64-bit builds, Linux on ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX. The low profile board measures 134.21 x 68.9 mm, so it fits compact systems as well as full-size desktop hosts.
