I am using Macbook pro retina 2014. I have just bought a LG TV 4k, but could not get the same scaling-options to fit the LCD (3840 x 2160).
This is the Built-Retina Display in Mac OS X before the Mac is connected to the TV through HDMI Port.
And the following picture is what I see on the LG 4k monitor.
The 1080 option seems to make the display less large the most.
Any solutions to integrate my Mac with 4K TV Screen?
