How do I know what version the Mini DisplayPort port is on my 2010 MacBook Pro?
I want to connect 2 monitors to my MacBook Pro (mid-2010). The problem is that I don't if the Mini DisplayPort is version 1.2, which would support daisy chaining. How can I figure out what version firmware my Mini DisplayPort uses and whether or not it would support daisy chaining?
The 2011 MBP (MacBookPro8,1) has thunderbolt, so either your machine is not a 2011, or it has thunderbolt. the 2010 MacBook Pros have MDP that supports audio as well as video (I have a 2009 which only does video).
Keep in mind that MDP and Thunderbolt look identical.
Open System Information, then under Hardware select Mini DisplayPort. This will tell you about the firmware of the port controller and more.

Key part:
6 Can other video adapters be connected or "daisy-chained" to Apple Mini DisplayPort adapters?
No, you should not connect Apple Mini DisplayPort adapters to any other video adapters. Connect your computer directly to an external display via one Mini DisplayPort adapter.
So, regardless of the version, I'd be cautious.
