I am assuming it is the cable anyway, I have 2 Macbook Airs and last night connected the TV to one of them but the screen did not display on the TV,

The Mac screen flickered, but the TV screen stayed blank and no external display was found on the Sys Pref. It was the same result with the other Macbook too!

The cable did feel hot so I am pretty sure it crapped out. I saw a few Amazon reviews for some of these cables and other people were complaining about the cables dying after a few months.

Does anyone know if the official Apple cable is more reliable? I prefer the single cable, and not using an adaptor but HDMI licensing means that Apple can't and never will make a direct cable! shame!

I ordered a new cable, so will see how it goes.

Do these carry audio? My adapter doesnt unfortunately.
Most cables do but check the descriptions. I think people have a problem when they don't change their settings.

From another discussion:

From what I read here prompted me to attach all components - go to System Preferences > Sound > Output. There I had an option Name: Panasonic TV Type: HDMI. Clicked this option Hey Presto I had sound through TV. Note this option only appears when you are connected to the TV.

What is it about these cables that can cause a failure?
I don't know, maybe cheap quality chips in them, I did buy a cheap one from Amazon.

As there is no official offering, it seems hard to know if we are buying something that will break quickly.

I am buying another one and hoping it'll last a bit longer:eek:
