Q: How to go from Firewire 800 or Thunderbolt to HDMI? Which one is the most efficient?, How to go from Firewire 800 or Thunderbolt to HDMI? Which one is the most efficient?

Welcome to Apple Support Communities

FireWire is a data port, so you can't use it. However, Thunderbolt is compatible with Mini DisplayPort, so you can buy a Mini DisplayPort to HDMI adapter and a HDMI cable to connect the Mac to your TV.

Alternatively, you can get a Mini DisplayPort to HDMI cable and you will save some money and space. This hasn't been tested, so I recommend you the first option

Thunderbolt and Mini DisplayPort have the same port. Mini DisplayPort peripherals work connected to a Thunderbolt port, so there's nothing to worry about

You are welcome

Exactly what adapter did you buy (your link goes to an Apple support page) ... and exactly what model MacBook do you have ... and exactly what make & model HDTV do you have ... what cable are you using from the adapter to your TV ... and are you using any additional adapters or plugs?

There is no special display driver; this should work as soon as you plug everything in and select the proper input on your TV.

You can use a Minidisplayport->HDMI hooked into the Thunderbolt's socket. Please note:

1) if you have TB periphehals attached, the Minidisplay port can be attached to the chain BUT as last. No matter what peripherals, the display will work as connected directly. Thunderbol is an excellent protocol.

2) many Full HD TV/display, TB apart, do display an horrible image. You need to modify a file which contains the parameters - if I'n not wrong - of the EDID. Sorry, I don't have the link on this machine, check into the forum.
