How to connect an early 2013 MBP to a 4K LG Television
Most Macs with an HDMI port (besides Mac mini late-2012 and older) support 4K, but are capped at 30Hz or 24Hz. The MacBook Pro Retina 15&quot; mid-2014 model supports 60Hz at 4K, but older models do not.
I personally have a MacBook Pro Retina 15&quot; late-2013 model, and it can only do 4K at 30Hz
(4K is defined in my answer as 3840 x 2160.)
