Ok. So when I first got my computer, I turned it all on and started it up and lo and behold there was about a one inch border around the edges of my monitor. After a fair bit of research I found out that the borders could be gotten rid of by going into catalyst and changing the overscan setting to 0%. I've sort of accepted this for 2 years now.
But of course, when I play DirectX 10 games... the overscan setting gets reset! But that's another story.
My main question is, why do I have to change the overscan setting? I know CRT monitors needed this... but in the modern age of LCDs why does it still exist? Is it some sort of grandfathered technology?
