Very interesting.

 

Subpixel arrangement is a very important factor from my experience as well. Especially if we play games like IL-2 that have a steady horizon, that we will not want to flicker too much when very even.

 

These can be pentile, or (better) RGB, and the latter can be arranged vertically or horizontally.

Yeah, PPD instead of resolution is what matters.

But it needs to be calculated both: horizontally and vertically, since panels have different resolution/FOVs horizontally and vertically.

The wikipedia link doesn´t take that into account, and some wrong FOV values from marketing pitch. 

 

Apollon01 was trying to approximate that taking subpixels as well:

It is a really complicated thing to measure from specs. Ideally there should be a common image pattern and a common special camera to simulate the eye to shoot through the lens pictures and count real pixels per degree.
