Sourav SatvayaSome basic info about USB
FierySpectreIt gets even better, each function of the port also needs proper support from the cable. Often cables do not support the full spec of usb to cut costs.
While the symbols in the post are often put on computers, for usb cables this is seldom done (only a few brands do).
Source: had to find a cable that supports both DP and PD to connect a portable external monitor after I lost the original cable. (1/9 cables worked)
Yes, this is incredibly annoying and it's also the reason why some USB cables cost more than others, even they may look the same superficially.
One of those cables that don’t work is rated for like 120W, with gigabit transfer speed… But it refuses to transmit display… Like bruh
That sounds like a dedicated charging cable. So yeah, they will (if at all) only transfer data slowly and not support any extras features like displayport.
A dedicated charging cable wouldn’t have “gigabit speed”
No USB cable has “gigabit speed”. It probably has 480 Mbps (USB 2.0 standard).
Maybe he meant a 5 Gbps USB 3.0 cable. That is would be “gigabit speed” but still rather slow by today’s standards. They are pretty cheap these days, so wouldn’t be suprising to see left over stocks being sold as charging cables.

What? I’m either misunderstanding you or this statement isn’t correct. Having USB cables that can move data at gigabit rates has been common for quite some years.
Here’s the latest stuff:
Bitrate
20 Gbit/s
40 Gbit/s
80 Gbit/s
120/40 Gbit/s asymmetric
What? I’m either misunderstanding you or this statement isn’t correct
I meant that no USB standard actually has exactly 1 Gbit/s. I even mention that next one if 5Gbit/s. Just a misunderstanding I think.
Oh, okay, makes sense, thanks.
