Plugable MDP to HDMI Adapter with HMDI 2.0 Not Pushing 4k Resolution @ 60Hz to 2016 4K TV.

Hey all,

I have just purchased the Plugable MDP to HDMI 2.0 Active adapter. I have connected it to my Macbook Pro Retina and connected it to my TV with an HDMI 2.0 Cable. However, the TV only sees the signal as 3840 x 2160 30hz and not the required 60hz.

Any help as to how I can achieve 60hz would be greatly appreciated.

Many thanks.
