Last month I bumped into an incompatible DisplayPort -cable. There are many different speeds and DP 2.0 requires so much more on your cable to achieve those speeds 4K, 5K and 8K monitors require.
A famous phrase states "Go big or go home!" So I did that. Went big:
These two cables with 8K and 10K spec should have the oompf required to run any of my future monitors.
Color-coding is puzzling to me:
No matter how much I do looking & searching, there isn't anything I can find on those colors. My obvious assumption is for the manufacturer Deltaco to mark 8K with a red connector and 10K with a blue. Exactly what cable speed that translates into, I dunno. My speculation is with UHBR13.5 and UHBR20, but that's only my guess.
In my previous post on the topic I did complain on lacking markings. The boxes have semi-reasonable markings, cables have none. Besides the undocumented color coding.
I you'd compare USB-A -connectors:
Or USB4-connectors:
Both have well documented system. DisplayPort, not so much.
