So your intuition for why squares makes sense is wrong, but you’re still holding on to it.

What does show it’s a good model is all the theory of image processing and the implementation of this theory in camera display systems.
You’re welcome to propose an alternative theory, and if that is consistent, try to get manufacturers to adopt it.

I said subpixels are rectangles. Because they are.
If the point model was all you need, then objects small enough to slip between points would be invisible. Which is not the case.
In particular a shot of the night sky would look pure black.
So if being wrong means we should abandon the model, then we can't use squares or points.

I look forward to your paper about a superior digital image representation.
So is this a cheap gotcha because I only said "my monitor" and "most screens" the first couple times and didn't repeat it a third time? It's the one labeled just "LCD".
Or are you arguing that the slightly rounded corners on the rectangles make a significant difference in how the filtering math works out? It doesn't. On a scale between "gaussian" and "perfect rectangles", the filtering for this shape is 95% toward the latter.
