Hi, I hope someone might be able to help me - I've really stuck! I have two flat screen TV's and I use a HDMI to thunderbolt adapter to connect my Macbook Air to them both to use them as displays. They have both previously worked fine. Suddenly, on one of the TV's (a Sony model) the colour of the display is red tinted when connected to my Macbook, in both HDMI sockets. It works fine from both sockets when connected to my Sky HD box. The HDMI cable and adapter work just fine when connected to the other TV. I have a brand new Macbook Air, although the problem was happening with my older model just a few weeks ago (I didn't copy all of my information over either). I realise that this is most likely an issue with the TV, but I'm just confused as to why it only does it when plugged into my Macbook! Any help would be massively appreciated Thanks!
