With Type-C and USB interfaces, it connects to most devices, making it ideal for online capture, real-time recording, online meetings, and live gaming, providing a smooth and enjoyable visual experience. Note: For capture use only; requires capture software to function and is not intended for direct screen casting to a monitor or TV
- 【Ultra-low latency without compression】 This HDMI to USB-C capture card supports easy recording of high-quality audio or HD video, YUY2 and MJPEG video formats,preserving the original video quality, making it ideal for professional video editing, live streaming and other applications requiring high-resolution, low-latency capture. 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
- 【PD 100W Fast Charging】 The device is equipped with PD 3.0 100W fast charging, which is plug-and-play for fast capture and ensures stable power supply for USB-C devices during live broadcasts or long recording sessions (charging is not supported by the USB-A adapter; Charging can only be performed on C ports that support charging). Note: A 100W charger is required to achieve the same fast charging speed; The capture card may heat up slightly during charging, but it's normal
- 【Easy to Carry, Efficient Heat Dissipation】 The HDMI 1080P video capture card is designed for convenience and does not require any additional drivers or external power supply. The sleek aluminium alloy case provides excellent heat dissipation to prevent overheating. Compact and portable design allows for efficient mobility, does not support the addition of an adapter for charging

- 【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
