My monitor has a dead pixel, and I used my discrimination distance RGB filter image to make this movie to simply fix it.

Hope that helps everyone fix their monitors if those funny graphics don't work,

And also let everyone know that even if the RGB filter is very close and closer than the subpixel gap, you can still see the difference in distance.

The subpixels are too close, and our eyes are far enough from the screen, they will be "synthesized" into a color pixel! This argument has been misleading scholars and the public for decades.
