Forums -> UltraMon™ -> Triple monitor wallpaper problems

Looking at a screenshot might help you understand what I'm saying below:

Logfile output of EnumDisp can be downloaded from:

I have three monitors, middle is the primary.
Things were working fine without problems until I switched the positions of the right and left monitors. Tt displays the wallpaper correctly in the preview of the Ultramon Desktop Wallpaper settings screen, but when you Apply the changes, the left and centre monitors strangely display the centre and right part of the wallpaper, and the right monitor displays the left part of the monitor. The taskbars and "Identify" features still work correctly, and the middle monitor is still primary. If I don't stretch the wallpaper over all three monitors, the left monitor displays it, even through the centre monitor is selected and the the preview shows the centre monitor displaying the wallpaper only.

I sometimes also get an error message on startup of Ultramon: "Mirror driver loaded before real display driver". I have looked in the help but I can't figure out how to disable the mirror driver. I also have disabled the Nview desktop manager.

Abit Geforce4 4400 - SVGA output to monitor #1 (centre)
DVI output of GF4 card connected to DVI2VGA adapter to monitor #3 (left)
Matrox Millenium 2MB connected to monitor #2 (right)

TIA for your help!

Perhaps it doesn't matter, but I forgot to mention that I quite often use the S-video out from my GF4 card (becomes the centre screen, replacing the centre monitor) which might account for the extra "Default monitor" entries in the log.

Please try the following:

- go to your wallpaper directory, usually My Documents\My Wallpapers

- delete the file 'Glacial Inferno.bmp'

- open the UltraMon wallpaper settings

- UltraMon should indicate that no wallpaper is active. Select Glacial Inferno and click on Apply

This causes UltraMon to regenerate the bitmap used for the wallpaper. Let me know if this doesn't fix the problem.

Erased the files in My Wallpapers, but there was only one BMP file, and it was Default.bmp which contained a wallpaper that I haven't used in months.

However deleting these files worked! (For a moment). The wallpaper was drawn correctly.
Then I tried resizing my centre monitor to 1280x1024, and it switched the left and right wallpaper positions again. When I went back to 1024x768, then the wallpaper was still screwed up, and no files were written to My Wallpapers.
(so I can't figure out how to fix it again).

I tried changing the wallpaper style to Center, and as you can see in:
the wallpaper should only be on the centre monitor, but instead it's drawn to the left, with a little bit spilling over onto the left side of the center monitor, and a little bit spilling onto the right side of the right monitor.

When I increase the resolution of the center monitor to 1280x1024 or 1600x1200, as you can see in:
then clearly Ultramon is confused about where the monitor display space is, because when it's resizing the wallpaper it draws it properly on the correct screens for a half second, then redraws the wallpaper on the wrong screens (and off-center for 1600x1200) and a weird white box appears in the corner.

I just installed Earthview, and it successfully spans a wallpaper across the 3 monitors correctly. When I quit Earthview, then Ultramon draws the wallpaper correctly, then redraws it as I have described above.

Hope this is helping your diagnosis.

Looks like you have stored the wallpapers in the shared folder, this is usually Shared Documents\Shared Wallpapers.

Please try what happens if you delete your active wallpaper, Glacial Inferno, in the shared folder as described above.

I found a bunch of wallpapers in /All Users/Shared Documents/Shared Wallpapers

I deleted them all, and then Ultramon says "None" for available wallpapers, as you expected.

But when I add a new wallpaper, the same problem as above still remains. Even at 1024x768 for all three monitors, the correct wallpaper is drawn for a split second, then the screens are redrawn incorrectly as I described above.
The white box in the corner is still there at 1280x1024 and above.

Sounds like a compatibility issue with some other application. Swapping monitors 2 and 3 shouldn't make any difference if you have a single image stretched across the desktop.

It looks like UltraMon creates a wallpaper for use without Active Desktop enabled, applies the wallpaper, then Active Desktop gets enabled and the wallpaper no longer looks correct.

If you have any application running which customizes the desktop, for example by adding a calendar or similar to the desktop, try disabling it and check if this fixes the problem.

Discovered that the problem is probably not ultramon-related, because on uninstalling ultramon the confused monitor enumeration problem remains. (off-centred, displaying wallpaper on the wrong monitor or not at all)

I suspect that Earthview has mucked with something that wasn't undone when I uninstalled it. (So be warned if you are thinking of trying out that CPU-hijacking program) I don't think reinstalling the OS is worthwhile just to make the wallpaper work properly. I'm using a solid black background for my three monitors for now - bleh.

I have the same problem with dual monitors. Ultra-mon puts left wall paper on right monitor. There is a compatibility issue with Earthview. I installed that and then all of this happened.

Oh, also. Change your wallpaper to the one you want and click apply, it will be all screwed up. Click on the advanced tab of the wallpaper window and uncheck "adjust wallpaper when display configuration changes". Close window. Open display Properites. Change resultion, click apply, change resolution back to what you want, the wallpaper will display correctly until you restart your computer, change wallpaper, change resolution, blah ,blah, blah.

After looking at my computer at work I think Earthview switches the monitors around in the settings. If you look above, on my home computer, display 1 is monitor 1 and display 2 is monitor 0. At work it's the other way around. Display 1 is monitor 0 and display 2 is monitor 1.

I have just tested with EarthView 2.0, the problem is that when you enable multi-monitor support under Options > General, a registry setting gets changed which causes problems for the wallpapers generated by UltraMon.

To fix this, open regedit.exe, go to the key 'HKEY_CURRENT_USER\Control Panel\Desktop', then delete the values WallpaperOriginX and WallpaperOriginY.

Have you tried reapplying the UltraMon wallpaper via UltraMon menu > Wallpaper?

this was the first result i hit when i googled "ultramon wallpaper problem" so i thought i'd share what worked for me. I on accident happened upon the other tab in the Wallpaper window and unchecked the box, switched around the position of the desktops in the order they were supposed to appear, applied the backgrounds, then reordered the monitors to my liking and the wallpaper held. hope that helps and makes sense.
