"Stuck pixels" appear only on XP desktop?

Recently purchased a 32" Sony XBR 1080p LCD TV to use as my monitor. Computer
graphics card (ATI HD2400) was connected to TV via HDMI cable. Two weeks
after installation, started getting a 1/4" high column of what appears to be
stuck LCD pixels center screen (white lower 2/3, red upper 1/3, looks like a
tiny kitchen match). It appears constantly on my Windows desktop (either
blank or over any photo I use for the desktop wallpaper) but is never on the
LCD screen during Windows startup, when viewing any other program, video, TV
or even the same desktop photo opened and viewed full screen in, say,
Photoshop, etc. If they were true "stuck" pixels, they should be there all
the time, right? Has to be within Windows. Any ideas what could cause this?
Any help would be appreciated.

Are you using the "recommended" resolution/refresh freq for the LCD?
They are sometimes finicky outside their recommended settings. Many I've
seen print the recommended res/rfrsh rate to the screen during say a
Restart while the screen is being re-addressed and momentarily without a
signal.

HTH,

Right-click Desktop, Properties, Desktop tab, "Customize Desktop"
button, Web tab. If there's anything in the box under web pages that
has a check mark by it, deselect it.
 
Thanks so much for the response. I tried what you recommended and, like
magic, the "stuck" pixels disappeared. How did you know what to do? Anyway,
thanks! You rock!
 
Tried downloading the latest drivers for the card, but it didn't help. Tried
"Elmo"'s suggestion and it worked. Thanks for the response.

I initially thought it might be one of those, especially a bad LCD. The
bizarre thing was that the pixels only appeared over the desktop, no matter
what wallpaper was in use, but not over anything else being displayed, such
as video, DVD, TV, games, etc. Turned out to be my wife's Virgin Health Miles
software she installed to download her pedometer info. Followed "Elmo"'s
suggestion and the pixels disappeared from the desktop. Really strange deal.
Thanks for your response.
