display question on TV

I bought the connector so i could watch TV shows that i missed on my TV from my computer, and it works pretty **** well. A few questions tho. My TV is 1080P and the connection is minidisplayport to HDMI. The picture on my TV is a little off centered, like the top bar of the desktop is gone. How can i fix this. I've selected mirror display and the resolution is the highest possible. Also the display settings are on "Color LCD". Any suggestions from you pros? Oh yeah the picture on the TV doesn't look like 1080P to me.

thanks

Changing the aspect ratio ON THE TV usually does the trick, for me at least.

Go through the different aspect settings on our TV and see if that works.

THere are tons of different verbiage for each brand, mine needs to be set to "Dot by Dot" in order to be perfect.
