If MrBig's suggestion of new drivers still does not resolve your issue, try adjusting the type of ratio the screen is on. I know in my situation using a lcd tv as a computer screen i had to push the ratio button on my controller till it went from "Tv view" to "cinema view" then to "Just scan" which made everything perfect.
As well as following the above reply, I did have to follow the same kind of actions relative to my own TV, enabling 'dot by dot' as opposed to 'full screen' on my Sharp model screen.
This also confirmed that I have now done everything to fix he setup of the card and my TV, thank you also!
Things are looking great now in 'dot by dot' 1080p!
Thanks to both of you guys for your replies!
