What the NJ700 does and who uses it

The Narvitech NJ700 is a 4K capture card built for creators who stream or record at 4K144. It connects via USB 3.2 Gen 2 and handles HDMI 2.1 signals from a PS5, Xbox Series X/S, Switch, Steam Deck or PC. No drivers are required on Windows, Mac OS, Linux, SteamOS, iOS or Android, so it works immediately with OBS, Streamlabs and Xsplit. Buyers who need internal PCIe capture or analogue video inputs should look elsewhere.

Build, connectors and daily use

The aluminium enclosure carries one HDMI 2.1 input, one HDMI 2.1 passthrough output and a USB 3.2 Gen 2 port that accepts either Type-C or Type-A cables. A 3.5 mm line-in jack mixes external audio and a second 3.5 mm jack carries party-chat output. Passthrough supports 4K144, 1440p144 and 1080p240 with near-zero latency, letting the connected monitor run at its native refresh rate while the card captures 4K144, 1440p60 or 1080p120 in NV12, YUY12, P010 or MJPEG formats. HDR capture is supported.

Included accessories and software impact

The box supplies the capture card, a USB 3.2 Gen 2 cable and a quick-start guide. Because the device is UVC compliant, no proprietary software or driver installation is needed; streaming applications recognise it as a standard video class device on every supported operating system. The bundled cable ensures full 10 Gbit/s bandwidth for raw or compressed 4K144 capture without extra purchases.

What does the HDMI 2.1 passthrough cap at for resolution and refresh rate?

What physical ports and cables are needed to connect this capture card?

It requires an HDMI 2.1 cable for video input and output, a USB 3.2 Gen 2 Type-C or Type-A port on the host, and optional 3.5 mm 3-pole cables for line-in and party chat audio.

How is the card set up, and what step do users often miss?

Connect the console to the HDMI input, the monitor to the HDMI output, and the USB cable to the computer; no driver install is needed, but users often forget to select the correct UVC format such as NV12 or P010 in OBS for 4K144 capture.
