Overscan... Help me understand!

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?

Thanks in advance.

Have read that. Doesn't explain why LCDs still need it. Theoretically, it should be a useless feature, especially for a modern GPU.

Overscan is still used on TVs, it cuts off the noisy edge of TV broadcasts. Are you using a TV as your monitor?

Nope. I'm using some inexpensive 23" computer screen. I'm guessing the reason for the overscan is because it's cheap.
