Display and Resolution Support—See the whole picture. This 40Gbps USB4 USB-C cable is Thunderbolt-compatible, with support for dual extended 4K screens at 60Hz, or one 8K screen when paired with a compatible hub or docking station
The new USB Power Delivery specifications allow for the delivery of up to 240W via a USB Type-C cable (an increase from the previous 100W max). The previous Power Delivery range has been relabeled as Standard Power Range (SPR), and the new specifications (between 100W and 240W), have been labeled as Extended Power Range (EPR).
While the TBT4-240W-1M and USB4-240W-1M are essentially identical in terms of specifications, the TBT4-240W-1M has passed Intel's notoriously rigorous Thunderbolt™ Certification, which makes it officially Thunderbolt™ Certified.
The USB4-240W-1M is USB-IF Certified, which is another set of high standards to ensure functionality and interoperability. While it is not officially Thunderbolt™ Certified, it is still fully compatible with Thunderbolt™ devices. The TBT4-240W-1M is also USB-IF Certified.
In either case, you can be confident that our cables will be compatible with your Thunderbolt™ and USB4 devices!
