Q: I connected my Thunderbolt™ 3 dual HDMI 2.0 adapter and can only get a single
output.
A: Please make sure that your Thunderbolt™ 3 host device can support two separate
HDMI 2.0 capable lines over Thunderbolt™ 3.
Q: How can I know whether my system has the necessary two HDMI 2.0 capable lines to
provide dual display output through the Thunderbolt™ 3 port?
A: Unfortunately, in many cases this information is very hard to discern based on the
manufacturers published specifications. If your system is not among those listed in our
compatibility above, please contact your system manufacturer for confirmation of how
many HDMI 2.0 capable lines are routed to your Thunderbolt™ 3 port.
Q: What if a newer compatible NVM is not available from my system manufacturer?
A: Unfortunately, the only option is to contact your system manufacturer and ask when
a newer version will be available, and to let them know that until it is, certain accessories
you are looking to use will not work.
Q: I connected my Thunderbolt™ 3 HDMI 2.0. adapter for the first time and my system
got frozen up.
A: Check to see if your system is running the latest Thunderbolt™ 3 software, NVM, UEFI
BIOS, and all other updates from your system manufacturer. If everything is updated,
unplug the adapter, reboot the system, and then reconnect.
Q: When I connect my Thunderbolt™ 3 device to my Windows computer, I get pop-up
messages. What do I do?
A: Unlike USB devices, Thunderbolt™ 3 devices must be manually authenticated
(approved) for use by the user before the system will recognize them. When you connect
a Thunderbolt™ device to any Windows operating system that can support
Thunderbolt™ 3, a pop-up message appears. To use your device, complete the following:
1. In the New Thunderbolt™ devices have been attached pop-up message, click OK.
2. In the User Account Control pop-up message, click YES.
3. In the Approve Thunderbolt™ Devices pop-up message, do one of the following:
•If you want to authorize your Thunderbolt™ devices every time that you connect
them, select Always Connect in the drop-down list.
•If you want to authorize your Thunderbolt™ devices only once, select Connect
Only Once in the drop-down list.
4. Then click OK.
