3840x2160 60Hz AND 2560x1440 scaled 60Hz (as well as other scaled resolutions). MBP with IG -> Dell-supplied mDP to DP cable -> Dell P2715Q: Success. 2560x1440 30Hz works, but is is obviously blurry and not scaled. 3840x2160 30Hz works, but there is no option for anything higher in Display Preferences. MBP with IG -> MDP-HDMI -> HDMI cable -> Samsung MU7000(HDMI UHD Color: OFF): Stuck at 30 Hz. This is my “goal” hardware configuration described above.

Please review my test results below before responding. The HiDPI scaled resolutions are important for my application.
My goal: 3840x2160 60Hz AND 2560x1440 scaled 60Hz on MBP Mid-2014 with Integrated Intel Graphics, Macos High Sierra -> MDP-HDMI -> Samsung MU7000 4K TV.
