2880-by-1800 native resolution is not a 5K display. Check again.


2880 x 1800 = 5184000

there are two ways to classify displays, one is the total number of
pixels (for the above, 5.2k) and the other is the horizontal dimension,
5120 x 2880, which would be 14745600 total pixels.


https://en.wikipedia.org/wiki/5K_resolution
"5K resolution refers to display formats with a horizontal
resolution of about 5,000 pixels."

So you have been caught trying to cheat.

nope. both are used. once again, you are clinging to rigid definitions
and ignoring real world usage.

Mort Linder:
What is the pixel array size in a 4K screen? E.G. 1920 x 1080?


It has to be 4,000 pixels horizontally, or close to that. That's what
the 4K means! 3840x2160 is one standard.

It's the same principle for 5K. The iMac Retina 5K has a resolution of
5120 x 2880 pixels, e.g.

I'm wondering how much sense a 4K screen on a 15" notebook would make.
In a shop I opened a 42MP image on a 15" notebook with 4K screen. It
didn't look that breathtakingly sharp.
Or to put it differently, is anybody using a 15" notebook with a 4K
screen and is it significantly sharper than a 15" notebook with a 2K
screen?


I went from a 2560x1440 27" iMac, to a 5120x2880 Retina 27" iMac. First
and lasting impressions are that they're not that different in
day-to-day use.

Close up the Retina display is astonishingly sharp in comparison. Up
close, text for example is noticeably pixelated on the lower res screen,
no pixelation on the higher. The Retina's backlight is more even.

But at normal viewing distances, not much difference - including photo
work. No regrets - I happened to have the money to afford the Retina
model (not that I had much choice if I wanted a new iMac).

I would add that I've nothing approaching the level of
interest/experience of most of you on this NG.

That said, I recently repaired a 2007 1920x1200 24" iMac, and its
display is mush by comparison to either.

Joe has told you that Apple uses the horizontal dimension. You seem to
be claiming that use the horizontal definition for the Mac and the
area for the Retina Macbook Pro. The closest that I can find to Apple
claiming that is that the Macbook Pro supports up to two 5K displays.
There is no claim that the Macbook Pro has a 5K display.

I gotta hand it to nospam. He can always be counted on to argue with
anything even if his argument conflicts with one of his previous
arguments.

Here he objects to clinging to rigid definitions and ignoring real
world usage. It seems like just yesterday he was ignoring the real
world usage of "long lens" and clinging to the rigid definition of
"long-focus lens".

He's never met a statement where he won't reply with "nope".

you are once again lying about what i said.

i said that people use the term long, long focus and telephoto lens
interchangeably, whether or not it's technically correct, the very
*opposite* of clinging to a rigid definition.

Coming back to the original topic, how much sense make 4K screens on a
15" notebook PC?

If they are not noticeably sharper, I would just buy a cheaper notebook
with a 2K screen.

No, no one in the "real world" uses "long-focus lens" interchangeably
with "long lens". Just in your little world of "nope".

"Long lens" is always used in a technically correct way since it is
used to describe what is technically what they consider to be a long
lens.
