Product Information
Full details
The j5create 8K USB-C to Dual HDMI Adapter (JCA465-N) is a high-performance connectivity solution designed for professionals, content creators, and gamers who need to expand their workstation with multiple high-resolution displays. It delivers stunning visual quality, supporting up to 8K resolution or dual 4K monitors at 60Hz, providing a seamless plug-and-play experience for laptops, tablets, and devices with USB-C, Thunderbolt 4, or USB4 ports. While it offers exceptional clarity and bandwidth, users should note that macOS does not support Multi-Stream Transport (MST), meaning dual displays connected via this adapter will only mirror each other on Apple systems.

Extended Product Information
FAQs
Does this adapter support power delivery to my laptop?
No, the JCA465-N is a display adapter only and does not support USB Power Delivery (USB PD).
Can I use this with a Thunderbolt 4 port?
Yes, this adapter is fully compatible with Thunderbolt 4 and USB4 ports.
Do I need to install any software or drivers?
No, it is a plug-and-play device and does not require any additional driver software.
What is the maximum resolution for dual monitor setups?
The adapter supports dual 4K resolution at 60Hz.
Will this work with my MacBook?
Yes, it works with MacBooks, but please be aware that macOS does not support MST, so both connected displays will show the same image.
Is an external power source required?
No, the adapter is bus-powered, meaning it draws power directly from the host device.
Troubleshooting
Displays are not detected by the computer.
Ensure your host USB-C port supports DisplayPort Alt Mode and that all HDMI cables are firmly seated in both the monitor and the adapter.
Dual monitors are showing the same image on macOS.
This is expected behavior as macOS does not support MST; the monitors will mirror each other rather than extending the desktop.
Resolution is lower than expected.
Verify that your host GPU and the video source support DisplayPort 1.4 with DSC. If the source only supports older standards, the resolution will be capped accordingly.

Setup, Compatibility & Care
Setup is straightforward: simply insert the USB-C connector into an available port on your host device that supports DisplayPort Alt Mode and connect your HDMI cables to the two ports on the adapter. Because the unit is bus-powered, no additional cables are needed. For maintenance, keep the adapter in a dry environment at room temperature, ideally between 0°C and 45°C. Avoid exposing the connector pins to dust or moisture. The device is compatible with most modern Windows and ChromeOS devices; however, verify that your specific hardware supports the necessary DisplayPort protocol versions to utilize the full bandwidth of the adapter.
