Oooh that's hard! My screen has value differences (which is what's being tested, not color differences) from top to bottom, and also some from left to right because it's angled. I got 28 but then had a black one and couldn't find it. I tried again with the display centered better, and still got 28 even though they were in a different order. How do you get 33? It stopped at 29 for me.
