Hoster Show Nightmare - A 3rd video card was used and dialogs moved to it

[Roy Dennis]

The only way I know of how to change displays over is in the Nvidea settings. If yours is the same as the one on my old XP laptop you can find it here. From the display properties window choose the advanced tab, from there you should see a tab with your Gforce or nvidea card name, on clicking this you should get a dialog window with a fly-out box, select Nview display settings this should give you a picture of 2 monitors (not the same as display properties) here you can select a different monitor to be the primary. Now I don't know if this will recognize your USB card as you are on your own with this.
Sorry I can't help any more on this, perhaps someone else will know about Registry key settings.

Roy.
