Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter
The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter lets you connect Thunderbolt and Thunderbolt 2 devices — such as external hard drives and Thunderbolt docks — to any of the Thunderbolt 3 (USB-C) ports on your MacBook Pro.
As a bidirectional adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port and macOS Sierra.
In addition, it can be used to connect Thunderbolt-enabled displays — such as the Apple Thunderbolt Display and LG Thunderbolt 2 displays — to any of the Thunderbolt 3 (USB-C) ports on your MacBook Pro. However, using this adapter with an Apple Thunderbolt Display requires a power source, because the display does not provide power through the adapter.
Note: This adapter does not support DisplayPort displays like the Apple LED Cinema Display or third-party DisplayPort and Mini DisplayPort displays. For more information, visit the Apple Support page for the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

If you mean the CJ79, then I think so. Thunderbolt 2 supports DisplayPort 1.2. Thunderbolt 3 supp If you mean the CJ79, then I think so. Thunderbolt 2 supports DisplayPort 1.2. Thunderbolt 3 supports two DisplayPort signals but I think only one is used for 3440x1440@100Hz (30bit color) = 14.9 Gbps so Thunderbolt 2 should be sufficient and there should be remaining bandwidth available for the USB 2.0 ports. Only the Apple Thunderbolt 3 to Thunderbolt 2 adapter allows connecting Thunderbolt 3 devices to Thunderbolt 2 computers so this is the adapter you need.
