How to get Windows 7 logon wallpaper to tile to other monitors?

Question

In 2000/XP/Vista it was easy to set a wallpaper for the logon screen, either manually through tools like Logonstudio or simple registry changes by hand on prepared installation images or through custom group policies.

In Windows 7 all this works as usual, but the secondary (or any additional) monitor is just black. The mouse pointer is visible on it but no matter what settings I can't get the logon wallpaper to tile (or stretch or fill or whatever) over onto it.

This makes it hard to OEM/company brand the installation for multi-monitor users. More annoying is the fact that it looks officially supported to brand the logon wallpaper in Windows 7 - as it's made extremely easy... apart from this little catch. XP and Vista has no problem tiling or stretching the logon wallpaper over multiple monitors.

I'm afraid this is not possible, as far as I'm aware the login GINA screens are only written for a single display source, thus preventing you doing what you are intending to do.
There may be some obscure tool out there to do it but I'm certainally not aware of one and have not come across one in over 6 months of looking, albeit on and off. ( I was trying to do the same on some of our Designers PC's)

on the plus side though there are many open source GINA's out there. perhaps there is one that suits our needs. i was reading an interesting article about them earlier: http://www.windowsitpro.com/article/security/pgina-open-source-gina-replacement.aspx

I'll have to check that when I get to the office tomorrow morning, but I don't think this is possible in Windows 7. (Though, honestly, I wasn't even aware that this was possible in older versions of Windows).

I'll get back to you if, or as soon as I figure out how to do this.

Update:

Nope - I'm not able to do this either. Please let us know if you figure it out! I don't think it's possible.

you could always press windows key+tab+p to change it to copy onto the other screen. i actualy have my logon stretched to both sreens, donty ask how, thats how it was one day when i turned on.
