Most 3rd party adaptors have little or no strain or twist relief in the cable attachment inside the adaptor. Alternatively, it is possible to get a more expensive powered active converter. Neither adapter are Apple branded, just generic. It still happens occasionally, but it's bearable. EDIT: After a while the Macbook Pro intermittently stopped powering the external display, leading to both displays flickering on and off more often.

There's a micro-USB port on the adapter which I need to plug into a power source, and it then works. There is a high probability that its Apple's System Integrity Protection that's stopping 3rd party adapters from working. I disabled this feature and added the driver for the adapter and it worked. There was a down side though, after this was installed the adapter caused my mac to crash twice.

It was causing Kernel panics and wouldn't start hence the name System Integrity Protection. Since I've restored without it I haven't had problems, it could of been the driver so you could just disable System Integrity Protection and see if it works. The connector costs about 25EUR. Here's what happened in my case. The brand is Sandberg. This adaptor also has a small slot on one side for the micro-usb. But the VGA monitor stayed black - no display at all.

Try setting your display to use the default resolution for the display from the same preferences pane discussed above.
