I am assuming you are using the HDTV as a 2nd monitor, and so your monitor is your main.
What I was saying is that when you open up your softwares/programs, leave it open on your HDTV, that way you can always see your desktop icons on your monitor.
If you want your Desktop Icons to show on your HDTV, you can make that the main display, and then use your regular monitor as an extension.
If you absolutely must have a;; desktop icons on both displays, just copy all your icons and paste it onto your other display.
