Not Just a Thunderbolt 3 Cable
Thunderbolt 3 brings data transfers at speeds up to 40Gbps over USB-C, enabling a superset of standard USB-C to truly become one compact port that does it all—delivering the fastest, most versatile connection to any dock, display, or data device.
For the first time, one port can connect numerous Thunderbolt devices, any display, and billions of USB devices (additional adapters may be required). Thunderbolt 3 cables are primarily used for connecting docking stations, high performance data storage solutions, peer-to-peer networking, and more.
Note: This cable is incompatible with Qualcomm Quick Charge and other (non USB-IF Power Delivery) “Fast Charge” technologies.
The Plugable TBT3-40G80CM cable is foremost designed as a Thunderbolt 3 cable, but it is also a universal USB-C cable for use with USB-C computers, phones, tablets, docking stations, accessories, and more. It supports all USB-C cable features, including USB 3.0 and USB 2.0 data lines, wire gauge supporting up to 5A charging via the USB-IF PD (Power Delivery) standard 100W max (5V-20V), and support for reporting its capabilities as an electronically marked cable.
A Cable That Does It All
Massive 40Gbps Bandwidth
Because the cable is designed for Thunderbolt 3, it is also capable of supporting data transfer speeds four times as fast as standard USB-C cables. The available 40Gbps bandwidth allows for dual 4K 60Hz video outputs (or a single 5K output) and up to 100W (20V, 5A) capabilities when used with compatible systems and Thunderbolt 3 accessories. Please note for USB-C usage this cable is limited to USB-C 3.0 (5Gbps).

How to Determine Your USB-C Port Video Capabilities
Understanding your laptop's video output capabilities is essential when connecting to external displays. This guide will help you identify what video technologies your laptop supports and how to find the relevant information.
Common Video Output Technologies
Modern laptops commonly use one or more of the following technologies to transmit video to external monitors:
1. Thunderbolt 3
- Supports video output using the DisplayPort protocol.
- Capable of driving up to two 4K displays at 60Hz or one 5K display at 60Hz.
- Uses a USB-C connector and features a lightning bolt symbol next to the port.
Note: An example of Thunderbolt 3 ports
2. Thunderbolt 4
- Provides improved performance over Thunderbolt 3.
- Supports up to two 4K displays at 60Hz or one 8K display.
- Uses a USB-C connector with the same lightning bolt symbol but may also include the number "4" for identification.
Note: Thunderbolt 4 has the same physical connection and “lightning” bolt icon as Thunderbolt 3
3. USB-C DisplayPort "Alt Mode"
- Allows video output directly through the USB-C port using DisplayPort technology.
- Commonly supports one 4K display at 60Hz, but capabilities may vary.
- Often marked with a DisplayPort ("DP") symbol, but this feature may also be specified in your system's documentation.
Note: An example of a USB-C port with DisplayPort capabilities
How to Identify Your Laptop's Video Capabilities
To determine what video technologies your laptop supports, follow these steps:
1. Check Your Laptop's User Manual:
- Locate your laptop's user manual (often available online from the manufacturer's support site).
- Search for keywords like "Thunderbolt," "DisplayPort Alt Mode," or "video output capabilities."
2. Visit the Manufacturer's Website:
- Go to the support page for your laptop model and find the technical specifications section.
- Look for details on Thunderbolt or USB-C video capabilities.
3. Inspect Your Laptop's Ports:
-
Check for identifying symbols next to USB-C ports:
- Thunderbolt 3/4 ports may have a lightning bolt symbol.
- DisplayPort Alt Mode may be marked with a "DP" icon.
“What if I do not have the above technologies?”: USB 3.0 (Type-A) and Display Expansion
While USB 3.0 (Type-A) ports do not support native video output, they can still be used to extend to two or more displays using software-based solutions like DisplayLink or Silicon Motion's InstantView. These technologies enable video through USB-A ports by utilizing dedicated drivers and software.
If your laptop lacks Thunderbolt or USB-C video capabilities, DisplayLink or InstantView may be a viable alternative for expanding your display setup. A few other things to consider:
- Not all USB-C ports support video output. Checking your laptop's documentation is crucial to confirm this capability.
- Thunderbolt ports are backward compatible with USB-C DisplayPort Alt Mode but provide enhanced performance and flexibility.
