Does anyone have a solid grasp on the hardware capabilities on the new MacBook Pros (13 or 15) to know if it'd power the 27" 5k iMac screen? I know I'd need at least a Thunderbolt 2 to Thunderbolt 3 cable, but would that cut it? The LG displays seem to be supported at 5k. The previous generation MacBook Pros were a no-go because of the t-con. Wondering if this new generation of hardware handles this?
