Can't enlarge desktop picture

[mike13]

My friend just bought a new Hannspree 22" widescreen monitor. When he hooks it up to his 6 year old Dell Dimension 5150, he can't expand his desktop picture to the whole size of the monitor. He is running XP Pro. I had him go into SETTINGS and try different RESOLUTIONS by sliding the bar etc. that did not work. He went into DESKTOP, and tried CENTER, TILE, and STRETCH, same problem. What am I missing. There has to be a setting to enlarge his desktop picture to the total size of the monitor. When the computer first boots up, he says the first couple screens like DELL, and the Windows XP screen are full size, but that is it. Suggestions, please Mike

SOLVED---He just calleed back and said the problem is fixed. He did not remember what he did exactly, but all is well.

He did not remember what he did exactly, but all is well.

He probably set the external screen as "main" screen. The old Dell probably being 3/4 ratio and the 22" being widescreen, you can't really clone one onto the other.
