Product Information
Full details
The j5create JCD403 USB4® 8K Multi-Port Hub is designed for professionals and power users who need to expand their connectivity options with high-speed data transfer and advanced display capabilities. Its key benefit is enabling a high-definition workstation setup with up to 8K resolution and 40Gbps throughput, while also offering robust peripheral and power delivery support. A key consideration is that achieving the maximum 8K 60Hz or 4K 144Hz resolution may depend on your host device's GPU and support for VESA Display Stream Compression (DSC). This hub consolidates essential ports including HDMI 2.1, Gigabit Ethernet, USB-C with Power Delivery, and multiple USB-A/USB-C SuperSpeed+ ports into a single, compact device.

FAQs
Does this hub require any drivers to work?
No, the j5create JCD403 USB4® 8K Multi-Port Hub supports Plug and Play. It should be recognized automatically by compatible Windows and macOS systems without the need for driver installation.
What is the maximum number of monitors I can connect?
This hub supports a single external display connection via the HDMI 2.1 port.
Can I use this hub to charge my laptop and power connected devices simultaneously?
Yes, the USB-C Power Delivery port supports up to 100W pass-through power, allowing you to charge your laptop while also powering connected peripherals.
What is needed to achieve 8K resolution at 60Hz?
To achieve 8K 60Hz, your host computer's GPU must support DisplayPort 1.4 with VESA Display Stream Compression (DSC). Recommended GPUs include NVIDIA GeForce RTX 20 Series / AMD Radeon RX 6000 Series or newer.
Is this hub compatible with Thunderbolt 3 devices?
Yes, the hub is designed with a USB4® controller that offers compatibility with Thunderbolt™ 4 and Thunderbolt™ 3 specifications.
What is the data transfer speed of the USB ports?
The hub features one USB-C and two USB Type-A ports, all supporting USB 3.2 Gen 2 (formerly USB 3.1 Gen 2) with data transfer speeds of up to 10 Gbps.
Do I need a separate power adapter for the hub?
The hub itself is powered via USB-C from your host device. However, to utilize the 100W Power Delivery feature for charging your laptop and connected devices, you will need to connect your laptop's original USB-C power adapter (or a compatible 100W charger) to the hub's PD port. The hub does not come with its own AC adapter.
Troubleshooting
No video output to the external monitor
Ensure the HDMI cable is securely connected to both the hub and the monitor. Verify that your host laptop supports DisplayPort Alternate Mode over USB-C and meets the resolution requirements (e.g., DSC for 8K 60Hz). Check if the correct input source is selected on your monitor. Restart your computer and the hub.
USB devices not recognized or not working properly
Try connecting the USB device directly to the host computer to rule out the device itself. Ensure the USB device is compatible with USB 3.2 Gen 2 (10Gbps) speeds or lower. Connect the hub's Power Delivery port to a 100W charger if you suspect power draw issues for multiple peripherals.
Slow internet speeds via Ethernet port
Confirm the Ethernet cable is securely plugged into the hub and your router/switch. Ensure your internet plan supports speeds faster than Gigabit. Check the Ethernet adapter settings on your computer and confirm it's negotiating at the highest speed (1000Mbps or 2500Mbps). Test the Ethernet cable with another device.
Laptop not charging when connected to PD port
Ensure you are using a USB-C power adapter that supports at least 100W output. Verify the power adapter is securely connected to the hub's PD port and the hub is connected to the laptop. Some laptops may have specific power requirements; check your laptop's specifications.
Hub is not recognized by the computer
Try plugging the hub into a different USB-C port on your computer. Restart your computer. Ensure your computer's operating system and USB drivers are up to date. Check if the integrated USB-C cable is damaged.
