LG has two new 4k TVs with HDMI 2.0 (49" and 55"), so it can support 60fps over that input. However, I've been scouring the internet looking for a DP 1.2 (from the nMP/rMBP) to HDMI 2.0 converter with little success. I imagine something like this has to be forthcoming though, right? I've also read conflicting ideas as to whether a firmware update could allow for hdmi 2.0 support on the nMP/rMBP. Here is the TV: http://www.amazon.com/LG-Electronics-49UB8500-49-Inch-Ultra/dp/B00II6VY2G What do you guys think?
