Computer screen display resolution too big.

I have a win 7 home premium HP P6-2203A computer. Ive noticed that the screen resolution is out of wack lately? The red exit button on the top right hand side is barely visible, I can still click on it but I would like to get it right again. Ive set the LG Flatron W2242P screen to the native resolution of 1680 x 1050 and Ive downloaded and installed the latest graphics driver for my graphics card.I dont know what else to do to fix it?

Ive right clicked on the screen and checked out resolution and AMD catalyst engine but cant find any way to do auto config? I seen it was already set to its native resolution! Ive right clicked at the top of the screen and ticked the menu bar the space opened up a bit and now I can just see the bottom of the toolbar on the far left top of the screen .Ah yes Ive got it now. I realized that I just recapped the monitor and now its working so much better the color is incredible,I set it to reset to factory settings. I didn't think that it was the monitor itself so thanks mate for steering me that way.
