> Computer hardware and software people could never figure out a reliable way to communicate the diagonal display size. It was just easier for the hardware and software to communicate the screen resolution and just punt on factoring in how packed the pixels were when rendering computer graphics. There was never commitment by the computer industry to deliver display output that matched real-world measurements. No, this is a HTML/browser problem. Since the days of DDC (late 90s) this worked plug-n-play. If, for example, you set a PDF viewer to 100 % then you will practically always get a 1:1 size reproduction that is basically dead nuts on.
