How to integrate Macbook Pro Retina with LCD 4K (3840 x 2160)

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?

I am the same boat with the Samsung 4K U28D590D. It seems our Graphic Cards all do not support 3840 x 2160 resolution.

According to Apple, the following Macs do support 4K resolution display (Ultra HD TVs):

  • MacBook Pro (Retina, Late 2013 and later)
  • Mac Pro (Late 2013)
  • iMac (Retina 5K, 27-inch, Late 2014 and later)
  • iMac (Retina 4K, 21.5-inch, Late 2015)
  • iMac (27-inch, Late 2013 and later)
  • iMac (21.5-inch, Late 2015)
  • Mac mini (Late 2014)
  • MacBook Air (Early 2015)
  • MacBook (Retina, 12-inch, Early 2015)

Only MacBook (Retina, 12-inch, Early 2015) supports 3840x2160 at 30 Hz
and 4096x2160 at 24 Hz.

You guys can buy a 4K display monitor for your Mac for bigger screen such as: Asus PQ321Q, Dell UP2414Q, Sharp PNK321 or Asus PB287Q…
They are all expensive of course :slight_smile:
