Hi all,

I was just wondering as I am currently looking for a new monitor for my MacBook Pro. At the moment I use a 24" screen that is perfect and I was just wondering that if I brought an apple thunderbolt display that has the extra thunderbolt plug on the back would I be able to link it up to the 24" I have now or a 28" I have downstairs so that I have the 2 monitors?

Thanks a lot

Kieran
 
You will be able to do that provide you have the right adapter. Mini display to ....
 
Correct. Look at THIS from Apple (paragraph under the numbered parts)

However, at the bottom of the FAQ:
Mini DisplayPort displays will not light up if connected to the Thunderbolt port of an Apple Thunderbolt Display (27-inch). Displays connected via Mini DisplayPort video adapter to the Thunderbolt port of an Apple Thunderbolt Display (27-inch) will not work. Connect Mini DisplayPort displays directly to a Thunderbolt port on a Thunderbolt-capable Mac or to a compatible Thunderbolt peripheral. If the Mini DisplayPort display is connected to a Thunderbolt peripheral, the display should be connected at the end of the Thunderbolt chain.
So MBP-->Thunderbolt Display-->Thunderbolt HDD-->miniDP Monitor,
might work.
I want to know as well..

AnandTech tested this with a 27" Cinema display at the end of the daisy chain, with a Pegasus TB in between, and it worked.

I tested multimonitor functionality with a 27-inch LED Cinema Display as well as a second Thunderbolt Display. In the case of the Cinema Display, as expected, I couldn't get video out of the port on the Thunderbolt Display. Connecting the Thunderbolt Display to a Promise Pegasus and then connecting a Cinema Display to it worked however. I also woke up the MacBook Pro's internal display and confirmed that I could get all three functioning simultaneously. There's a definite slowdown in UI frame rate with two 27-inch panels being driven by the MacBook Pro's integrated Radeon HD 6750M. It's not unbearably slow but kiss any dreams of 30 fps goodbye.
However, on AppleInsider, the last display being a projector didn't work.
