There was a recent question discussing dotted overlays/dithering patterns on images, and I wanted to explore the method. I set it up so it was one black pixel, one blank, one black, etc. After duplicating it to cover the page, I found that it created what I can best describe as monitor flicker, or maybe banding? Something's happening on my screen. Here's a screenshot; see if it does the same to you!
What causes this, and how can I minimize it? I found that using other colors helped, but I'd much rather understand why than pick colors and hope it works. I know that monitors are very different from each other, so I'd like to know that if I get it right on my screen, it'll be right on other screens.
