Woot tech experts, I need your knowledge! I have a portable monitor that had a USB-C cable that supported both power and video, which I promptly lost. Does a cable need to specifically state that it supports video? I assume data transfer isn’t the same thing.
TIA
I believe the USB 3.1 gen 2 allows for video transfers up to 4k, this cable should do the trick.
Make sure the cable you’re talking about isnt a thunderbolt cable! They look almost exactly the same. I think thunderbolt ports have a little lightning bolt by them.
What length is this cable?
Gen 2 cables for just 4 bucks? What’s the catch here? Do these have the devil in them or something that you have to let them go this cheap?
These are USB C = Thunderbolt.
Are you warning about Lightening cables?
In the case of a device requiring thunderbolt 3 or 4, 10Gbps may not be sufficient. It may hold your displays refresh rate back. Im not 100% on compatibility, I don’t have any devices that use thunderbolt
They do share an identical header, tho.
I don’t understand this chart. What does the left most column represent? It’s not “port type” because a USB 2.0 port maxes out at 480Mbps. And a DisplayPort uses a completely different type of cable. What am I missing?
These are all “USB-C” cables, but each of them are rated for different speeds, based on the generation of USB , or ThunderBolt.
So the left most column represents a USB-C cable that is rated for USB 2.0 speeds. This has nothing to do with power delivery / wattage. This is strictly for reference to data transfer. You may have, say, a 60W USB-C cable that charges really fast, but it may be only capable of transferring data at USB 2.0 speeds (480Mbps).
ThunderBolt is just a classification of USB-C cables that are capable of high data transfer, and video. There are some displays that actually use USB-C in the form of ThunderBolt cables instead of DisplayPort/HDMI. In that case, the display that uses ThunderBolt may not be compatible with any USB-C cable, but things like chargers that use USB-C are backwards compatible with ThunderBolt.
The measurements under the ThunderBolt cables refers to the max transfer speeds at that length. Once you create more physical distance in the cable, the data transfer speeds go down. So for Thunderbolt 1, it can do a max of 20Gbps at 1 meter. Past 1 meter, the speeds may go down.
Thanks.
To me, that chart is extremely convoluted for what it is trying to convey.
Here is a less convoluted summary for people with brains like mine.
For cables with USB-C style connectors, look at the symbol to determine its max data speed (but not charging wattage)
Basic USB Symbol = 480Mbps max
SS USB Symbol = 5Gbps max
SS 10 USB Symbol = 10Gbps max
Thunderbolt Symbol = 20Gbps max up to 2 meters
Thunderbolt 3 Symbol = 40Gbps max up to 2 meters
@Wooter498609399 If I’m missing something or still misunderstanding, please clarify.
Nope, all of what you’re saying is right. Though, this symbol is not always there, it does signify the USB version. You can also see these symbols next to their respective ports. For instance, laptops usually have one or two “SS” or “Super Speed” USB ports, which are capable of operating higher data consumption devices, such as Document/Photo scanners, etc.
The chart is more of a visual on USB generations and their max data capabilities. So if you buy a USB C cable and it says what USB generation it is, this chart basically tells you the max data transfer capabilties of that. . What I find weird, is the last 2 thunderbolt cables not having every dot in them.
These are NOT 3 feet in length. Very disappointing.
Sorry for the issue.

You’ve commented on 2 occasions w the same comment disputing the length of the cable yet provided no info regarding the actual accurate length of the cable. If you’re going to dispute the accuracy of the length, twice, it’d be helpful to others to mention the true length.
Not 100% sure but according to the Amazon listing it says 3 feet.
That’s what s/he said!
LOL
I just received mine a few minutes ago and they are in fact 3ft long. 36" tip-to-tip.
So as I mentioned in one of my comments that I just received these cables quite recently. I thought I’d mention to future buyers my observations.
The cable appears to be well made and quite sturdy. The cable is encased in thick rubber (not the now typical braided cable) and because of this, it is quite rigid and will not easily lay flat. It charges my Lenovo laptop (with a proper high power USB-C power supply) which is my gauge of being an acceptable “high-power” capable charging cable.
