    I wanted to expand my desktop to my tv. So i borrowed my friend's Dynex mini displayport to HDMI. I have plugged it in in many different ways, reset the pram and nothing. Every time I plug it in, the Macbook's screen goes blue for a few seconds and POOF! nothing happens :(. I got it to work one time and that was only after some INTENSE wiggling :mad:. does anyone have any sugestions?

    Try toggling various resolutions and aspect ratios. The painless way to do this is to enable the menulet icon in Sysprefs->displays and then test different resolutions from the new icon on the menu bar.

    The resolutions for the tv do not show up. If i plug it in, the macbook screen goes blue and nothing changes. if i take it out, it turns blue again and nothing changes. I'm beginning to think that the adapter is crap

    Now and again I have the same problems connecting my MBP to my Sony Bravia TV via HDMI & a mini displayport adapter. I've found that if you have the tv set to another input, connect the cable, wait for the MBP to do its display detection and then change the tv input to the computer, the display detection will run again and the tv will display the desktop. Sometimes the TV needs turned off and on again before the connection will work.

    Just got the new displayport adapter. It works, no wiggling necessary! turns out that not all adapters work well with thunderbolt because my friend's dynex adapter works fine with his 2010 macbook pro but not with my 2011 macbook pro. To anyone looking for an adapter, i recommend the one by Portta from amazon. it works with thunderbolt and costs under $3!
