This gets into the technical details more than I am able to, but I agree completely. I also have older eyes, and 4k was just unusable (on a Galago with a 13" screen). I could have scaled down by a factor of two, but that was too coarse.

I exchanged the Galago for a 14" Darter, and 1920x1280 is just right.

The Pangolin looks pretty nice to me.
