Capture Device for Gaming and Streaming
This HDMI 2.1 capture device records gameplay at up to 4K144 HDR and passes the signal through to a display. It streams 4K60, 1440p120 or 1080p240 over USB-C 10Gbps. The unit is built for console players and PC streamers who need low-latency capture with variable refresh rate and HDR support.
Check Your Setup Before Ordering
Your source must output HDMI 2.1 and your computer needs a USB 3.2 Gen 2 Type-C port running at 10Gbps for full bandwidth. The host operating system should be Windows or macOS with QuickTime available. Capture software such as OBS Studio or VLC must be installed to record or stream the incoming video feed.
Bundled Audio and Scaling Features
A four-pole 3.5mm jack on the box lets you plug in a headset and adjust game or chat volume while recording. On-board scaling converts the incoming 4K120 HDR signal to 4K60, 1440p120 or 1080p240 SDR for the USB stream without extra software steps. The HDMI loop-out delivers the original 4K120 HDR image to your monitor unchanged.

Questions about this item
Does the SIIG capture device include an HDMI cable and a USB-C cable in the box, or do I need to purchase them separately?
The package contains the capture unit itself; HDMI and USB-C cables are not included and must be sourced separately.
Should I pick the 4K144 Hz, 2K144 Hz or 1080p 240 Hz mode for my setup?
Choose 4K144 Hz HDR for maximum detail on a 4K display, 2560x1440 144 Hz for high-refresh 1440p monitors, or 1920x1080 240 Hz for competitive 1080p gaming.
What does the 4K120 Hz HDR pass-through figure mean when I am actually recording?
You can play at 4K120 Hz HDR on the HDMI loop-out while the USB-C stream records at 4K60, 1080p 240/120 Hz or 2560x1440 120 Hz in SDR.
