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.
