MJPEG:4K/60HZ, YUY2:4K/25HZ, XRGB:1080P/60HZ. Note: For capture use only; requires capture software to function and is not intended for direct screen casting to a monitor or TV
- 【High Refresh Rate Input: 2K@144FPS & 1080P@240FPS】Handles high-frame-rate video input including 2560×1440@144FPS and 1920×1080@240FPS. Supports MJPEG, YUY2, NV12, and XRGB formats, providing smooth, detailed video capture for fast-paced games and dynamic content using a reliable HDMI to USB-C capture card. Please use a USB 3.0 or higher port to connect the device. USB 2.0 ports only support up to 1080P resolution. If the device still outputs 1080P when connected to a USB 3.0 or higher port, please rotate the capture card’s USB-C connector 180° and reconnect
- 【90° Right-Angle Design for VR & Mobile Comfort】The ergonomic 90° right-angle USB-C connector with a 3.3ft cable makes this 4K switch capture card perfect for VR headsets like Quest series and portable tablets, keeping cables out of the way for a more immersive experience

A 100W charger is needed for optimal charging speed. Mild heating is normal
- 【Note】This capture card supports one-way transmission (HDMI to USB-C). Video input via USB-C to HDMI conversion may cause signal loss due to cable protocol differences. If the PS5 shows a black screen, please disable HDCP. Use a USB 3.0 port whenever possible to ensure bandwidth and resolution. The capture card works through video decoding, which introduces millisecond-level latency, and different video formats (MJPEG, YUY2) support different resolutions. Signal loss may occur if the device disconnects; reconnect or restore default settings. To check if the capture card is functioning properly, connect the USB port to a computer or tablet and open your capture software to confirm detection
