Retina 5k iMac not with 5k Resolution ?

[NordmoleX]

Please forgive me for probably asking something stupid, but when the 5k Retina Display is 5k, how comes its standard to something more like 2560x1440 ?

Whats the point of a 5k Display, if its not 5k. I dont have my iMac for very long, and as its being my first Mac, i always wondered how it looks absolutely not 5k.
Anyone explain that to me please ?

Sorry, if its unintentional funny ^^

It's a scaled resolution. The display is running internally at 5k, 5120x2880. Everything is being rendered at 5k. It's just that it is scaled at 2x, which makes it the size of 2560x1440. The size of that resolution. not actually that resolution. It's Hi-DPI scaling, and all super high resolution displays (that have proper software beneath them) do it.

If you don't like it, go to Display under System preferences, hold Option (Alt) and click Scaled. You can now pick 5120x2880 without a scaling factor. However, this will make everything tiny and result in less sharp text, imagery, etc. This is the reason for the scaling in the first place.
