How to connect the macbook with thunderbolt display 27" to TV with RGB port?

Question

Hi,
I have the following equipments in hands:
1. Macbook PRO 15 inch with 1 thunderbolt port, OS is Mavericks 10.9.2
2. Apple Thunderbolt display 27" identical to this : http://www.apple.com/displays/
3. A Samsung TV with RGB port, & HDMI port.
I want all these displays ( macbook, Apple thunderbolt display & the Samsung Tv) connected at the same time, I had a trial to connect them using a minidispaly adapter to RGB port & HDMI port  in the TV but it didnt worked.
Please help!
Thank you.

Answer 1

The Thunderbolt dock adds extra ports:
HDMI (up to 2560x1600 with the Elgato, 1920 x 1200 with the CalDigit)
3 USB 3
Ethernet
Audio in
Audio out
You could also use a Belkin Thunderbolt dock.

It includes a FireWire port, but no HDMI port, so would need a Mini DisplayPort to HDMI adapter (1920 x 1200 max) for the TV.  This would use the second Thunderbolt port, so the Belkin dock has to be used with the port on the back of the Thunderbolt display, not between the computer and display.
If you don't need the extra ports, use a Thunderbolt hard drive (with two Thunderbolt ports)

This can be your Time Machine drive.  Connect the Thunderbolt display to the computer, one port of the drive to the port on the back of the display, and a Mini DisplayPort to HDMI adapter to the second Thunderbolt port on the drive.
You will have three displays with differing resolutions, so mirroring is not going to fill each screen at full resolution.
