Does the MacBook Pro (Retina, Mid 2012) output 2560x1600 to the HDMI port?
The reason I ask is that I would like to drive 2x30 inch 2560x1600 monitors while still using the Gigabit Ethernet adapter. (My backup plan is to get the USB 2 to 100 Mbit adapter and use that and then just use the Thunderbolt for graphics). So I would appreciate any additional caveats to this plan as well.
