alternative to ultramon ? (dual desktop)

Hey there, i will get a 42" plasma tv soon and it will be most times be connected to my laptop via hdmi. Now i wonder if there is a free alternative to ultramon ? I only need the feature of different wallpapers on the monitor + changing them every 30 minutes. Any ideas?

thx bb

 

Here is what I found. LINK

Another possible solution would be to edit your photos together into one image and set Windows to "tile" the background. The result should be a different image on each display. Add that to Windows 7's feature that changes the desktop background every 30 minutes and you should be set.

 

I think the displayfusion program does the wallpaper thing

 

thanks for the link but none of them offers what i need with the free version. also displayfusion doesnt :/

i already thought about making 2 wallpapers to one but:

my laptops display = 1680x1050 and the tv is 1920x1080

so i would have a small image and a bigger one.. no idea if that will work but i will give it a try

@edit:

i have just tried it with photoshop.. lol my wallpaper would be 77mb oO the original pictures were 5mb + 2mb or smth

@edit2: with paint it works fine. but i could only try it on a beamer yet with 800x600. hope it works fine on the plasma tv too

@edit3: okay works fine thanks for the help

 

try dexpot, virtuawin, or another virtual desktop thingie to see if that will do what you need.
