x800 goes to large screen not monitor in Windows

[boe]

I have a PC with both a monitor and a large screen attached. When I boot
into windows, it automatically turns off the monitor and goes to the large
screen - is there a way to reverse this? Is there a way to make it go to
both?

When it boots, both devices are on.

Thanks

Right after driver installation the ATI drivers seem to give the DVI port
preference. Be nice if they remembered the previous settings. Just go
into the control panel (right click on the desktop, pick properties, then
display settings, then advanced, then displays) and set the one you want to
use as primary. If you want to use both then set clone mode on the
secondary--it should go to that automatically when you set the monitor as
primary, but you may have to click the appropriate button.
