Re: Cannot Mirror Desktop in Vista Home Premium
In the Control Panel, on the left side, there is a menu of "Tasks"
One task is "Connect to a projector or other external display"
When you select that, you get a dialogue that lets you chose mirrored or extended desktop.
quote==?Utf-8?B?dXNhc21h?=;57514]FWIW - we did find a workaround today. The latest nVidia drivers are Vista
certified, and installing the nVidia Control Panel let's you set the option
in there. Still, it's a bit disappointing to have to use another application
when the capability is supposedly built into Vista.
