No, I mean high pixel densities all the way to the display.
SSAA is an even older technique than MSAA but the results are not visually the same as just having a really high-DPI screen with no AA.
Up to a point. I would argue that 8K downsampled to 4K is practically indistinguishable from native 8K.
