Stupid question: Can a computer program tell me the characteristics of a USB-C cable connected to it? (potentially with nothing at the other end)
For instance I would plug a USB-C cable into my computer, start the program, and it would say "This cable supports Thunderbolt and can be used to charge at max 5A 100W, its data throughput is 40 MB/second" or similar.
Is such a program physically possible?
 
Not a stupid question, but I don't believe it could be done
 
actually considering how damned confusing USB C is...
its not a dumb question
 
I beleive the cable properties are only known, once you're communicatiung with a device at the other end
there's no 'inteligence' in the cable.
 
So if I connect my nuclear station to my superlaser through a flimsy cable, the devices will "try" to send power, and somehow realize that the cable is not good enough to send all of these amperes? Rather than the cable saying "Hi, please don't send more than 0.5A through me"?

seems about right
 
9:38 AM
KJind of
by default, upto 0.5a is provided (or whatever the standard is, pre usb-C)
However, a USB C cable allows communications which the host and the client then go 'how much power you want homie?' and the client responds 'Power level 3!'
at which point it provides HIGHERVALUEamps

@djsmiley2kStaysInside BCP allowed ... 1A?
@NicolasRaoul poor cable = higher resistance = higher voltage drop at higher currents = sink detects lower voltage = sink reduces current draw
 
12:11 PM
@djsmiley2kStaysInside isn't that also things like QC/USB PD, which are "added on" to the base spec?
@djsmiley2kStaysInside also, apparently USB C cables seem to have ratings...

We’re excited to share the results of our 10th annual developer survey! 65,000 developers shared their thoughts on the state of software today.

Thanks everyone for the feedback! I ended up posting as a question based on your ideas ^_^ superuser.com/questions/1555520

Are 4K monitors easier to read text from?
 
depends how big the text is
if it is point 8 font then you might struggle
 
6:13 PM
@northerner I have two 4K monitors. I set the DPI in Windows 10 to 200%, and everything is still crystal clear
