Hi Guys!What are these 'drums' on VGA cables that I've marked with RED arrows? Do they have an effect on the output/input of VGA signals?

I have two types. One cable has smaller 'drum's than the other. The cable with the larger ones work with the monitor/TV. The smaller ones don't give a signal to the TV VGA input while there's ghosting on the LCD monitor.

So, does this mean that the cables have different specifications?
