Monitor Screen Off Center

New here so please be gentle. (not to computer literate either)

I just bought a new monitor, now that I got it started up it seems like the screen area is messed up. There is a black line on the left side of the screen a centimeter or so wide and it travels vertically along the entire screen. Same problem on the left side, except slightly smaller.

If I use the controls to adjust the width and length it just moves the visible portion of the screen "through" the black portion.

I tried my best to explain what I could, any help is appreciated.

 

Does the monitor have little pictures that look like tv screens showing which one needs to have a light under it to expand the monitor sideways?

What's the brand of the monitor?

 

Start by using the controls to reduce the size of the screen as much as possible. It sounds like you have "foldover" from an image that's way too wide. If you start with everything shrunk down as much as possible, you can then adjust it properly without any ambiguity.

 

It is a KDS. It seems like what I am seeing is the actual viewing area. Which is smaller then the screen itself. When I adjust the height and width it expands past the black, but the black remains. And a small white dot shows where the screen *should* be showing up.

 

I must wonder if the monitor may be defective.........for example, and I'm not into centimeters, but right now I have a monitor that is dying.....there is about an inch and a quarter on each side, and no matter what I do, it remains the same.....every once in a while, it will expand to its normal size........but I know that it is on its way out........but it's about 6 years old or more.........
