Mini DisplayPort to HDMI Cable
Has anyone else experienced recurring 'going to sleep' issues for their 2010 MacBook Airs when connecting to a Sony HD television set using a generic Mini DisplayPort to HDMI Cable? Is there a setting I need to change? Pertinent if I am streaming from the web (e.g. WWDC keynote speech or from BBC iPlayer; I am in the UK so I can use it, that's not the problem). I can get the thing to work for 30 seconds and then it goes to sleep and only shows again on the TV if I touch the trackpad. There must be a setting that I can change which I haven't worked out yet. Thanks in advance for your help
