Retina pixels what? Pixel is a pixel, density _of pixels_ is what you're looking for

"Retina" is Apple's marketing name for high PPI displays.

Exactly. Retina is not "pixels" though or type of pixel

I think they mean "but those pixels are very small, right?"

6016 x 3384.

Dell monitor is twice the surface area with 3/4 the pixels … or in reverse: Apple display is half the size with 30% more pixels.

(edit: corrected dell pixel %)

What is going on here? Why is everyone in this thread using 'pixels" to mean ppi? It seems unnecessarily confusing or even misleading. I mean blatantly a 6K monitor has more pixels than a 5K or 4K one, regardless of the pixel density.

Yeah, nobody’s saying a 5k monitor has more pixels than a 6k.

I think what people are trying to communicate, but struggling to, is that high pixel count on a huge display can be deceptive.

I think grandparent was trying to say “comparing a low-poi display to a high-ppi display is not a direct comparison.”
