I never could reconcile the "variable geometry pixels" with my meagre understanding that they all had a matrix / mesh / mask at front, I think for separating individual colour pixels... Didn't they? Edit : here it is - shadow mask and trinitron. These feel like extremely fixed, physical native resolution? https://en.wikipedia.org/wiki/Shadow_mask https://en.wikipedia.org/wiki/Shadow_mask

So TechnologyConnections made two Vids about that very topic https://www.youtube.com/watch?v=dX649lnKAU0 https://www.youtube.com/watch?v=dX649lnKAU0 https://www.youtube.com/watch?v=Ea6tw-gulnQ https://www.youtube.com/watch?v=Ea6tw-gulnQ It's...complicated.

  That sounds really similar to subpixel rendering as used in AMOLED displays and their diamond/pentile subpixel arrangements. I found a demo online illustrating this http://www.clivemaxfield.com/area51/do-not-delete/pentile-rgbw-demo.html http://www.clivemaxfield.com/area51/do-not-delete/pentile-rg...

A subpixel on an LCD can only have a single brightness value across its whole area. The dots or stripes on an CRT have no such restriction, they are effectively little monochromatic pictures themselves. Don't think of those dots as fundamental elements of the image, the CRT doesn't address them and doesn't care about their shape. They are really just a color filter on top of the three greyscale images projected by the electron gun. The shadow mask ensures that each of those three electron streams land on the right color. See the TechnologyConnections video for more details.
