Yesterday I picked up a 2014 15" MacBook Pro Retina. 2.3Ghz, 16GB RAM, 512 SSD, 2GB NVIDIA GeForce GT 750M. I did a time machine restore from my 2012 MacBook Pro Retina backup to the 2014 Macbook Pro Retina. After the restore I installed 10.9.3 update. When I connect the 2014 Macbook Pro to my Sony 65X900B 4K TV I'm still seeing 25Hz and 30Hz as options like on my 2012 model. Shouldn't the 2014 model support 4K @ 60Hz with 10.9.3?
