I need help restoring my screen size

[mycatownsme]

I don't know what I did but my screen does not fit from edge to edge anymore like it used to.
I must have hit something and now I have about a 2 inch black border on the right and left side of the monitor.
I have Vista with internet explorer.
If anyone has an idea of how to get this back to where it was, I sure will appreciate it.
I tried to do a system restore but that didn't work. It said I could pick a different restore point but I thought I'd try here in case anyone can help me out.

I the window to fit fom the top to the bottom but I still have about an inch and a half of black area on each side.
I sure wish I knew what the heck I did to change this to begin with.
Thank you for the help.

you could try system restore

[mycatownsme]

Ok. I'll give it a try again. The first time I did that, it said it didn't work. This is the craziest thing.
I hope it helps to get this back to where I was.
Thanks again for the help.

It's only on my user name that I have this problem.
The other users screens are fine.
I sure do thank you for trying to help me out with this.
Maybe when I turn this computer off for the night, it will fix itself. 
Oh well, gotta think positive.

Right click any area on your desktop other than an icon. Left click personalize. Left click Display settings. Set resolution to high, move arrow all the way to the right. You may need to reboot, can't remember. This is for Vista. Good luck.

When you said other users are fine is this a shared computer and who has admin rights.   If the change was made under the admin user you may need to use the admin account to set it right.

[mycatownsme]

Yes, I went to admin user and Yes, I did move the arrow all the way to the right. 
Now. it's Back to the way it was. 
Now I'll need to check to be sure my autos run.
Thank you for the help.
