Moire is a thing that start to show if the image resolution is higher then the screen resolution and there are details which falls right between those two resolutions. the screen driver does downscaling at a certain patern and drops/delete details in that patern which causes those moire effects. (in the old day’s your tube tv did the same on tweed colberts of newsreaders now most have FHD so it isn’t an issue mostly, yes greenscreen errors are now like a cut off legs by bad choice of trousers )
When you zoom to say 75% you start to match the capability’s of the screen.
If you downscale the export to the screens resolution or at least 75% of it you will notice it’s gone.
i bumped in the same issue:
So buy a 8K screen and your problems are gone.
