After you have positioned them to the side, you can cover them with white paper. Doing so will reduce eyestrain and allow you to continue using the display.
Let’s imagine your black spots appeared in a circular shape. To cover them with white paper, you need to cut out a circular shape that is the same size as the spot. Place the paper on top of the black spot and attach it with transparent tape.
