It can be. I saw a spark the one time I tried it, so I never did it again. Generally, I never mess with connections like this when my computer is on.

Can you do it? Yes. I've done it A LOT. Lots of others have done more if not the same. Pin 16 is for Hot-Plug detection. Getting a spark removing or plugging it in? I'd say a broken 5v pin (14 & 15) or bad grounding for the monitor or computer itself. (In the work I do, I find devices back feeding voltage all the time because they have a broken ground or a reversed neutral in the house.) They, the DVI connectors, do have a limited life expectancy. From what I've read, around 100 or so cycles. So yes it is safe but you can but if you want to play it really safe, shut it down.

100 or so cycles? Does that mean plugging in and unplugging? I'm assuming so.
