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 Gen1 cable. That would be “gigabit speed” but still rather slow by today's standards and won't support DP. 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:

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.
