Resolution detection in JavaScript

Hi everybody,
I have a web site that is best viewed with a 1024x768 pixel display or better. Is there a way to detect what resolution a person is using? This would enable me to tell the people who are using lower resolutions that they are using a bad resolution for my site.

Thanks

screen.height
and
screen.width

Code:

---

function getRes(){
var intHeight;
var intWidth;

intHeight = screen.height;
intWidth = screen.width;

}
