can't stretch the picture on my display properties

[mark]

hi, i'm using win xp pro sp3. previously, i can stretch the picture even with
an 800 x 600 one with webshots to fit on my LCD monitor asus vw192d, now it
can't. i have put a check mark on webshot properties-wallpaper-enlarge
picture to best fit desktop. i even tried the windows display properties by
stretching but to no effect, by the way, windows wallpaper pictures works
fine-it can be stretched, tiled or even centered. my screen resolution is
1280 x 720 (32bit) ATI radeon 9550/ x1050 series. please help.... thanks.

Mark, did you check your refresh rate. Instead of 60, try 70 or 75 at
that resolution.
