I've got an iMac desktop computer. Love it. I wish to connect it to my LCD TV using HDMI. There is no HDMI output on the iMac so i had to buy one of these bad boys :-
So now I can output video (via the mini Display Port) and sound (via USB) through this box, to my LCD.
Works great ... with a single direct cable.
I have another 3 or 5 metre cable inserted into my wall, so i do not have to have a silly hdmi cable floating in the air between my iMac and my LCD TV. When I do this, there is no picture.
To better explain all of this, I've made a quick video explaining my problem in detail, so you can exactly see what is going on/wrong.
I've also tried changing the output format for the TV from 1080i down to 720p and even lower .. incase the cable in the wall doesn't allow 1080i.
here's the video with the full explanation :- http://www.youtube.com/watch?v=ZkKRKnRIh6Q
(NOTE: I incorrectly said in the video that the hidden wall cable is 10 metres long. me == fail. It's 3m or 5m...).
Can someone please watch it and suggest some ideas to getting it working?
