Why can't it reach 40Gbps for me?
1. Please check whether both the connected device and the cable support the specified bandwidth or resolution.
2. For a stable connection, keep the total combined length between the device and the cable within 10 feet.
Why can't I achieve 8K/4k resolution with a hub?
Please make sure that the hub and cable you are using also support 8K/4K.
Why is the connection loose and unstable?
1. First, ensure the USB-C port on your device is clean and free of physical damage.
2. Try flipping the female adapter and reconnecting it to the device.
