Been away for two weeks on holiday and come back to this problem
I have recorded what I looks like on Battlefield 1 as I can't really describe it.

You can see in the video around the carpets on the wall there is some strange shading around it. It is only slightly visible on the video but is very noticeable on screen. I have changed DVI cable and change the monitor the game is on to make sure that it is neither of those problems but it still persists.

Any ideas?
