I am using XP pro got a reply from manufacturer and they say it's a XP driver limitation:
-----
The hardware, does, indeed support dual monitors. The limiting factor is the operating system drivers.
If you are using Windows Vista, you will be able to Clone and Extend Monitors.
If using Windows XP, you will only be able to clone. This appears to be a limitation of the Drivers in XP because Vista allows for Extending and Cloning as its been tested here.

I don't see anything about this on the Intel Driver page for the 945G or 82945G Express Chipset.
Are there any other chipsets or tweaks that anyone can think of that would allow for 'Extended Desktop'
и
well I can't get XP to work with dual monitors and extend desktop with the 82945G Express Chipset but I can get Vista and Beta 7 to work. The only trick was I couldn't use the latest driver for 82945G I had to go one back. So I'm real happy now that 2 monitors are back, a bit bummed that I can't use XP but I need to move on to another OS sometime
beerandcandy, thanks for all your replies and help.
Это ограничения драйвера XP (в описанном случае 2 встроенных в мать порта). он не может рулить 2мя портами
так что качем все версии драйверов и пытаемся (может повезет:smile_nod:).
если в биосе и безопасном все работает, то значит железо может.
