TIA for your help.  I know there are already threads about mulitple monitors, but my specifics are slightly unique...


I currently run a 42" TV from the DVI port using an HDMI adaptor cable.  Works great.


I'd like to add a 20" monitor (Dell Ultrasharp, lots of connectivity options) and a 17" (older, less connectivity options).



I'll never need all three on at the same time.  One of the new monitors would display the same signal the TV gets; the other monitor would be a second screen.


What's the smartest way to do this?  From my reading I figure it will involve a powered splitter of some kind.  Does my 4870  have enough power to drive the two smaller montiors plus the 42" TV? 



(I also have a 2011 MBP I could throw into the mix, but I'd rather just run everything off of the MP if possible.)



A semi-detailed explanation of what products I need and how to use them would be most appreciated.  Looking for the simplest, cheapest solution.
