Questions & Answers for Apple Thunderbolt Cable (2m) - White

It will, but you will need an adapter to connect the other end of the cable to your new Mac’s Thunderbolt 3 port.
However, that is only for data transfer. I’d assume you’re trying to use the DisplayPort connection to use Target Display with your second iMac. You’d need a third-party USB-C to Mini DisplayPort adapter for that.

If you go to the Mac accessories and go into cables, you will find cables and adapters for thunderbolt to HDMI. an important note is that they will say Mini DisplayPort, not thunderbolt..

Thunderbolt is a point-to-point interface, that also allows daisy-chaining to up to seven devices. The new iMacs have other ports besides just Thunderbolt out their back, so in effect it already is a hub for these different port types. IF you want to chain via the Thunderbolt port, you need to make sure each device connected to your iMac has two Thunderbolt ports, one for its "upstream" Thunderbolt partner and one for its "downstream" device chain. Be careful, though, for not all Thunderbolt devices have this second port, so they have to be wired into your string as the last/end-point

I know a few weeks have gone by, but if you're still looking, you need a "mini DisplayPort to HDMI cable". I can't put a link in here so just Google that term in quotes. You can pick one up from Apple, or from online suppliers like Monoprice.com.

Note that the 2009 MacBooks won't pass sound through the mini DisplayPort, only video. So you will need a separate audio solution. Mine was to run a 3.5mm stereo cord from my MacBook's headphones port to a Logitech portable speaker. You can also just listen through the computer's speakers if you want.

Yes, the iMac late 2009 supports Target Display Mode (TDM)

Cable Supported: Mini DisplayPort to Mini DisplayPort

Port on Source Computer: Mini DisplayPort or Thunderbolt

Thunderbolt ports are backwards compatible, meaning they support MiniDisplay Port cables. Your iMac 2009 with MiniDisplay Port does not support Thunderbolt. So you will need a Mini DisplayPort to Mini DisplayPort cable; this would then be plugged into Mini DisplayPort in 2009 iMac and Thunderbolt port on 2014 iMac.

Command F2 on the 2009 iMac would put this computer into TDM, with the 2014 iMac as the source computer.

No, you cannot use a thunderbolt cable to connect a non-thunderbolt monitor. You have to get a Mini DisplayPort cable instead. Even
if your HP monitor has a socket that seems to fit, a thunderbolt cable cannot display any picture.
