Asus released a new USB4 PCIe Gen4 x4 card that provides 40Gbps bi-directional I/O bandwidth for USB with display output, versatile daisy chaining, and quick charging for several devices. With this card and a compatible motherboard, you are future-ready for USB4 devices, compatible monitors with DP-ALT mode, and portable devices that take advantage of the 65W quick charging available for both ports.
This USB4 PCIe Gen 4 card has two Type C USB4 ports and DP-IN ports. The USB4 standard supports a bi-directional bandwidth of up to 40Gbps, and the display outputs comply with the DisplayPort 1.4 standard; therefore, it supports 8K if your GPU supports this resolution. The main benefit of using DP 1.4 via USB4 is daisy-chaining between monitors with DP-ALT mode while being able to connect to a few USB4 devices through a single port.
