It is not your screen, I see it too, and it does not alter if you slide the image across the screen.
It's Moiré patterning, the same effect as you observe if you look through the folds of lacy curtains or gauze. Just a coincidence that the spacing of the weave in the focussed image is almost the same as the pixle spacing in your camera. If you try the same photo at a slightly different range or magnification, it will disappear.
