I have an A1418, Late 2012 version and I'm having trouble locking down an answer to how many external monitors it can support. Right now I have the iMac and two external monitors via the two Thunderbolts. The monitors are non-Apple, non-Thunderbolt.

Is there any way I can add an additional two monitors? Can the A1418 support a total of 4 external monitors? Some sites say yes, others say no. What say you?
