If you have a 5k iMac….Everything so microscopic. There is no zoom or that is what 5k is all about?
It will be on a 24” screen….m4 imac. 4480 x 2520 is small.
Excellent explanation. You should watchEverything so microscopic. There is no zoom or that is what 5k is all about?
Apple have marketed their monitors/iMacs as 4k/5k, but in reality they are not.
Nope - it's the other way around. Unless you've jumped through hoops to enable "low resolution" modes, what Apple calls "2560x1440" is actually 5210x2880, but with with fonts, icons, vector graphics etc. drawn using double the number of pixels so that they are the same physical size on a 27" 5k screen as they were on an old 27" 2560x1440 screen. Unless you're using ancient, pre-retina software that doesn't understand retina mode, those pixels are used to add detail and 5k mode shows far more detail than you'd get on an actual 2560x1440 screen.Which means a 4k is 1920x1080 and a 5k is 2560x1440 (half of 4 or 5k).
Sounds like you've selected "5120x2880" mode thinking that you need that to get 5k resolution. You don't. Apple, in their infinite wisdom, decided to use names like "2560x1440" to mean different UI scales.Everything so microscopic. There is no zoom or that is what 5k is all about?

Of course everything is small, it's only half the size (a quarter of the area) of what it's designed for!m4 imac. 4480 x 2520 is small.
I appreciate your correct explanation….. 👍Yes, they are: Apple have just chosen a very confusing way of describing the user interface scaling.

Just take a screen shot, count the pixels and zoom into some text or graphics to see that all of those pixels are being put to good use.
Being ‘old-school’ though I prefer more screen real estate with a higher resolution, so I wouldn’t feel I was getting anything more than my QHD displays, except a sharper image…🥴
No. it doesn't.This "halves" the resolution in both directions (width and height), so the "working resolution" is a display that "looks like 1440p".
You two appear to be actually in agreement, just using different words. Although, I guess you can argue about which words to use, I suppose.No. it doesn't.
The resolution of Apple's "looks like 2560x1440" mode on a 5k,27" screen is 5120x2880 (~220ppi on a 27").
It's pretty easy to check - take a full-screen grab and notice that you get a 5120x2880 image - then zoom in and see the detail.
Or, go to Display Settings, option-click on a screen mode, select "show all resolutions" and you can toggle between "2560x1440" (which is the HiDPI mode) and "2560x1440 (low resolution)" (Or the corresponding two "1920x1080" modes on a 4k display - same principle) so you can see what 2560x1440 resolution actually looks like, vs. HiDPI "looks like 2560x1440" (it really doesn't).
Or just load up a graphics program and make some 5120x2880 grids with 1-pixel gaps, set the zoom to "actual pixels" scale (or display the image full screen) and you'll see that the resolution is 5k.
"looks like 2560x1440" is Apple's (confusing) way of saying "it's 5120x2880 but with UI elements the same size as they would be on an old 2560x1440 iMac/Cinema Display"
(Then there are the fractionally scaled modes which are even more confusing but still render more detail than would be possible at the true "looks like" resolution).
Unless you're running ancient, pre-retina software, HiDPI mode doesn't halve the resolution - it doubles the numbers of pixels (in each direction) used by fonts, icons, line plotting etc. so they are the same physical size as they would be on a 2560x1440/110ppi screen, but they can still have 220ppi worth of detail and the actual content is still rendered at 5k...
Sigh. It's been 10 years since Apple sold a non-retina screen, about time they stopped using it as the "reference" for screen scaling. Instead, a few versions ago, they dropped the "looks like" just to make the mode names more misleading...
