Solved Taskbar slightly peeks over desktop image when hidden

At the bottom of my desktop/screen, I can see a thin line of the top of the taskbar. I have the taskbar on auto-hide, but tried it locked, unlocked, hidden, etc.
I tried different resolutions, restarts, images, and moving it. (It does it on all sides of the screen.)
I tried detect and identify in the resolution feature.

I did have this problem before and can't remember what I did to solve it. It turned out to be simple, but I just can't get it this time.
Thanks

(The thin blue line at the bottom of the image, not the big white vertical bar.)

As far as I know, there's not much you can do about it. It has to be there so that your mouse pointer can activate it. The physical window that makes up the taskbar has to have a mouse hover message sent to it, and that requires part of it to be present on the screen. This is the way it's always been.

mine shows a small fine line ,could it be that you monitors horizontal setting is off a bit,up to high toward the top of your monitor ,just a thought

I found the answer. I switched from a dvi plug back to a vga for my monitor.

So your solution is to cut off the bottom few pixels of your monitor..

I don't think it cut anything off. I think it's the vertical adjustment difference between how my Asus mon renders VGA and DVI...I guess. The taskbar now goes all the way out of sight when it hides...truth is, I don't know what the hell happened...it works. (and I remember that it is the way I fixed it before.)
