I'm pretty much at my wits end with trying to figure out how to solve my problem with my Mac Pro showing a full screen on my Sharp LCD TV that I use as my monitor.

I have posted a full article on my blog with pictures detailing my steps and screenshots, I would be INCREDIBLY grateful to anyone who can help me out.

I am even able to give a small reward (iTunes gift card) to the first person who can successfully solve my issue. I have a problem with making the black boarder around my desktop disappear, when I "overscan" the 1080p resolution I go TOO big and I cant see the dock or sides.

I've tried multiple software programs to fix the situation but I just either cant figure it out or am unsuccessful. I know Im sounding a bit desperate, I appologize, but thats because I am lol.

Thank you in advance,
