Need help with screen size, not filling up all monitor space

[lanceman011]

Hello, i recently installed windows 7 and am loving it except for one little problem. i have a 23inch monitor, and ever since i installed windows, it doesnt fill up the whole monitor (so its like i have a 20in. or so). if anyone could point me in the right direction to fix this would be much appriciated. thanks.

i have the correct screen resolution and the drivers are installed. I went into the BIOS and didnt find anything on video config..
