I'm having an issue wherby when viewing something (video/media) at full screen, the display will intermittently distort and/or skip frames (briefly go 'black' for moments). This happens with YouTube media through Firefox, iTunes movies at full screen, and other generic content at full screen. When the picture is distorted, the content of the media can still be seen, though the screen goes fuzzy/crackling. When I've captured/taken a screenshot of the screen the artefacts do not display.

You have the latest OS updates? Have you tried the hardware test? If so, how far are you from an Apple Store? They could test your hardware more thoroughly. https://support.apple.com/en-us/HT202731
Thanks for the reply, @Sanpete. I have the latest OS update, I believe, 10.12.3. I recently did a new install of Sierra (restore) too. I've tried the hardware and it detected no faults. I'm not far from an Apple Store, so that would be my next port of call. As I say, occasionally the screen goes fuzzy momentarily, which is different to what I describe where it goes black. Most of the time, everything is fine. I have to say since my original post, I've notice the problem not limited to full screen media, but any general usage too.
This do sound like hardware issue, logic board or the display. If your lucky it's just the contact between the display and the logicboard that are loose. Take it to apple store and have some kind of picture or video of the issue, if it's a display defect it might not show up on the diagnostic as they need to watch the display for a long time if I did understand you correctly?
