Re: How do you access second display adapter without being a desktop extension?

[Please do not mail me a copy of your followup]

"Sam Brown" <subiNOSPAM@xxxxxxxxxxxxxxxxxxxxxxxxxx> spake the secret code
<VcGdnZGZoZ8fUiXYnZ2dnUVZ8smonZ2d@xxxxxxxxx> thusly:

To show up in the adapter ennumeration, the device needs to have
the "Extend my Windows Desktop onto this monitor" option checked
in the display settings. Otherwise, DirectX can't see it.

I don't believe this to be true; you have to extend the desktop onto
it for GDI to see it. DirectX doesn't care about which devices are
attached to the desktop.
