Mini Display Port to HDMI and SONY TV?!?!

I apologize if this thread has already been posted, however I looked and nothing quite fit my question properly. So if your going to reply about that this has already been posted, please, save yourself some time.

ANYWAYS! I just bought a brand new 22" Sony Bravia TV and I also got a HDMI cord and a Display Port to HDMI adapter so I could hook my MacBook Pro up to the TV. The MacBook recognizes it is hooked up to the TV and the screen flashes blue for a second but the TV just repeats "No Signal". Any suggestions?!
Thanks!

Check in your System Preferences > Displays, and make sure you have it all set up correctly in there, also check that the resolution you have selected is supported by your TV.

Hope this helps

i agree with buzzard as well as sometimes just a restart of the computer fix's it.... ohhhh & are u sure ur on the right hdmi input selection.... i made that mistake... hahahah

Nothing worked, I suppose my TV just isn't compatible.
