I am planning to buy newly refreshed mid-2014 base 15" model with iGPU (Iris Pro). Since I'm not into gaming nor video/photo editing, I really don't need the dGPU. My plan is to use this computer for a good 4-5 years.
I will probably buy a 4k monitor when they become cheaper and want use it at 60Hz. However, I can't find any solid information or shared experience that says 15" rMBPs without dGPU can drive 4k @ 60 Hz.
I know rMBPs have HDMI 1.4 and it can drive 4k at only 30Hz, so it's not a question. But I read that Haswell H-class processors are capable of driving required amount of bandwidth for 4k through Displayport 1.2, but I'm not sure what happens in real life.
1. I'd be glad if anybody shares their experience about it?
2. It could be a rare user story but good to understand the limits: is it also possible to run two 4k monitors at 60Hz and also built-in monitor?
