Okay so to update - My 3 monitors are:
Today I went to apple and purchased new Thunderbolt cables in case their was a issue there. No issue. Daisy chained all 3 monitors and then into the USB-C to Thunderbolt 2 adaptor (MMEL2AM/A). Still only 2 monitors worked. Next I plugged in 2 monitors daisy-chained into one port on the right side of the 15" Macbook Pro with 460 Radeon Graphics Card, and then I plugged the 3rd monitor by itself with another of the above adaptors on the same side (as there is 2 plugs on each side on the 15") and nothing. Still 2 monitors. I then plugged the one by itself (not daisy chained) on the left side of the computer and walla - I now have 3 monitors working! BUT that is still frustrating becuase one of the main reasons I bought this mac is that it is supose to be able to handle 6 monitors. Are you kidding me - it looks like only 2 monitors per port!!!!??? I thought that was the whole purpose behind USB-C & the Thunderbolt idea was to be able to daisy-chain off each other. Its very irritating that i have now had to use all my ports on my mac just becuase I can not daisy-chain 3 monitors? Anyone else come up with this same scenario?
