Monitor Resolution Correct? (2018 Mini / LG 5K Ultrafine)

I have my 2018 Mac Mini connected to an LG 5K Ultrafine display using the cable supplied with the monitor (Thunderbolt/USB-C). The two are said to be compatible by Apple and indeed they are in that the display works fine and looks really good, but…


If I use Apple Logo>About This Mac> Display, the resolution is given as 5120 x 2800 (5K) but in System Preferences>Displays>Scaled the Default resolution says "Looks like 2560 x 1440". Which resolution is correct and if the lower one, what have I done wrong to not get 5K?

Mac mini 2018 or later

Thanks tbirdvet - is there no way to change my resolution to 5K to take full advantage of the monitor's pixel count?

If you were to set it to map display data to 5K, everything, especially text, would be very tiny.
