I'm trying to use one wallpaper on one monitor and one wallpaper on the other, but nothing is working. Is it even possible?

I don't think it is. It's been awhile since I've worked on a machine with dual monitors but as I recall, the wallpaper that was set worked across both screens. If the picture wasn't big enough for both you'd either stretch it or have background space where the picture isn't. Have you tried adding both images together as a single huge file and then using that as wallpaper? That might work.

I ran dual monitors back in the day.

I used a wallpaper made for 2 screen though, I think. I don't really remember too much. Do you use a switchbox?

Hmm. That makes sense. Maybe I can try doing that.

No, I just have my Dell monitor plugged into the back of my laptop. I then just drag my mouse across the screen and then it appears over on that monitor.

Thats really cool. When I ran dual monitors, it was a real pain. I had to configure my video card and I had to buy a switchbox. Its not really worth it unless you actually put it to use.

I think I have seen it done..
