The external display's max. resolution is 2560 x 1440, but the maximum resolution I can select on the display settings is 2048 x 1152.
What can I do to use the display in its max. resolution?
System: elementary OS 0.4.1 Loki
Display driver: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
