    Alright so I did some research regarding the viability of hooking up my 2011 iMac through MDP/thunderbolt to my Samsung LCD TV and most people were recommending the mono price adapter. I purchased this mono-price mini display port to HDMI adapter

    and then got a 10m HDMI cable to connect to my TV. I can't detect the display though and everything I try isn't working. Tried through Bootcamp as well and it's a no go.

    Anyone had any luck connecting their iMac 2011 to a TV? I hope I haven't spent all this money for nothing, I'm in Australia so it was a big hassle getting the adapter shipped over. :confused:

    the problem does not have to be the iMac or the TV , most times the problem i found is the HDMI cable , the quality differs so widely thats like the difference in performance between a iMac G3 bondi blue from 1997 and a iMac i7 from 2011 both are computers like all cables with a hdmi on both ends are Hdmi cables , but thats about it with the similarities

    you take one cable from manufacturer XY at say 2 meter lenght its perfect , you go to 5 m + and you got rubbish from that manufacturer at another manufacturer you got the opposite great at huge lengh , but rubbish on shorter distance , my advice buy in a shop that allowes you to try some different manufacturers and its not always the high price model that works great ...mine now is a chinese 10 meter cable for £2 i found on ebay after trying out more then a dozen others before and it works whenever i want

    there was a Monster cable i think it was around £180 for 5 meters , it worked too sometimes but i'm not willing to spend £180 on a hdmi cable

    Thanks for the response mate. Funnily enough after an hour or so of trying, it's now working perfectly in both Lion and Windows 7. I changed some settings with the TV so maybe that was the catalyst? Anyway it's all good now, cheers.

    What settings did you change on the TV?
