Why are computer screens off-bordered?

[PurpleMetro]

If you move your mouse all the way to the left of the screen, it's hidden.
All the way to the bottom, it's hidden.
All the way to the left, it's prevent's you from going off the screen.
All the way to the top, prevents you from going off the screen.
Why does this happen? :/

It doesn't happen. It's just a problem with your computer.

Never knew why this happened.

Well, no actually it doesn't hide it at all.
If you look closely you can see the black outline, it prevents that one pixel which you click on from going off-screen.
And it's like that because if you didn't have it bordered off, you could move your cursor really far down and not know where it was.

I will tell you why. Your mouse points at the top-left corner of its "sprite." If it did not go off of the screen you wouldn't be able to click icons on the far right or far bottom of your screen.

Its so that your mouse doesn't go off screen, and the actual mouse is the top pixel of the pointer.

The actual "point" of the mouse cursor is the very top left pixel of it.  The rest of the pointer is just a sprite to help you see it..  The "point" is the only thing that is boxed inside your screen.

god damnit everyone stop saying what i was going to say.

its because the actual mouse that you can use doesnt go off screen, but the icon for the mouse does. only one pixel of the mouse icon is left, because you can only click with the pixel exactly where the arrow points.

Because the very top pixel of the mouse is what clicks. If the sides bumped into the side of your monitor and prevented you from going all the way to the side, you wouldn't be able to click some things possibly.

guys I don't think he understands what pixel is used to click yet

[Mega-Bear]

Because only the top left pixel of your mouse is really used, the rest is just a sprite which is the only thing that can leave the screen.

On the default pointer for Windows the entire left border of the pointer is actually visible if taken off screen.
