So, I wanted to tell you an actually EFFECTIVE solution to the problem with the cintiq's 3-in-one cable.
Okay, so the problem is that the metal tip that plugs into the tablet bends super easily. You can just bump it and, boom, it's bent and you're out the cost of a new cord. Which aren't cheap and usually out of stock.
First, keep a backup cable on hand. As soon as plug in a new one, order a backup. Just in case.
However, to avoid having to use your backup, here's a product that is actually effective keeping that connector straight and safe.
Buy the 2.0 version because it has a little more support for the cord, holding it in place really good. It is a little annoying to have a bump on the side of the wacom that you sometimes bump the side of you hand on, but way less annoying than continuously replacing the expensive cable.
I'm not sure if this is the brand I originally purchased, but it looks the same except for mine had the wacom logo on it (which I wondered at the time if they were technically allowed to use since it's an aftermarket part) and this one says badrobot instead. I think it's the same guy and maybe he was asked to remove the logo? I dunno. It's basically a 3D printed adapter that you snap onto you cintiq and thread your cord through as you plug it in. The thing holds the cord pretty solid so that even pretty rough handling isn't going to bend that easily-bent metal end. It installs in a way that s removable, in case you need to transport your cintiq or something. However, my cintiq never leaves the vicinity of my PC, so I used some electrical tape on the back to get it really solidly adhered. It's not going anywhere now. It completely solved all my cintiq cable problems.
