I think I've found a bug with the way Vista handles dual screens and
I'm sure there are PLENTY of us who have dual monitors. For those of you who
do, try this:
1. Make sure Aero is enabled, and that your taskbar is always transparent.
2. Download any dual screen capable wallpaper program. For instance,
Ultramon, DisplayFusion, etc.
3. Set a DIFFERENT WALLPAPER PER MONITOR. Make sure to do this.
You'll see THROUGH the transparency of the taskbar that the wallpaper schema
is screwed up. There is a small part of the wallpaper that is cut off at the
bottom right, around the system tray icons, and looks like the wallpaper
repeating, or is confused with the wallpaper on the secondary monitor.
Here is the only way to work around this that I've found out so far:
1. Setting the taskbar to Autohide solves the problem (wallpapers display
behind taskbar properly).
2. Changing the schema of monitors within the display properties. If Monitor
1 is on your right and Monitor 2 is on your left, you will have this problem.
If Monitor 1 is on your LEFT and Monitor 2 is on your RIGHT, the problem will
3. Disable dual screen (not feasible).
4. Disable dual wallpaper ability (again not feasible).
Edit: More information.
I have 2 monitors. One is 1600x1200, which is the main one (monitor 1). The
other is 1280x1024, which is the secondary one. As stated previously, the
secondary is to the left of the primary.
Here is a screenshot. Explanation below.
Ignore the black border around the 1600x1200 image on the right, it's the
way the image is; same goes for the black bars on the top and bottom of the
left, since it's a 1280x1024.
Bottom right of entire screenshot. See the grass through the taskbar? It's
supposed to show through the ENTIRE taskbar, not just the bottom right. Now,
look at the Ultramon Smart Taskbar on the left. Notice something wrong? It's
showing the bottom of the RIGHT SCREEN WALLPAPER (notice the green grass
This is what I'm talking about. It does this no matter what drivers I use,
no matter what program I use for dual-wallpaper, and no matter what options I
For the sake of conversation, I UNINSTALLED Ultramon and the nVidia drivers,
and reverted back to about 3 sets that were 2-3 driver revisions earlier than
the latest. Same problem. I think it's fair to say that Ultramon is out of
the picture, since it did the same thing even with it uninstalled.
Even more evidence that the issue might be Vista and not nVidia or Ultramon.
The developer of Ultramon blames Vista everytime someone brings up this issue.
If anyone knows how to point me in the right direction concerning this, I'd
