Too much personal preference with PPD. When I upgraded to a 32" monitor from a 27" one i didn't push my display through my wall, it sat in the same position.
Not entirely clear on what you mean, but if you refuse to reposition your display or yourself after hopping between diagonal sizes and resolutions, I'd say it's a bit disingenuous to blame or praise either afterwards. Considering you seem to know what PPD is, I think you should be able to appreciate the how and why.
