Display Assistant allows you to show specific windows on your secondary monitor while you work on that window on your primary monitor. While presenting a slide show, you have tools like Presenter View that allow you to see your slides and notes while the audience sees the slide show. The typical setup allows you to face your audience while the slide show is presented on a screen behind your back to the audience. This allows you to see and connect with your audience while you are presenting. But when you want to show other documents, spreadsheets, websites, etc., you need to move the window to the secondary display to show it there. Essentially, you lose the document window from your primary monitor and now you have to look at your slide show display to refer to it. You effectively lose your connection with your audience and worst of all your back is now facing the audience. Display Assistant helps you retain your connection with your audience for a smooth and effective presentation. Display Assistant allows you to clone or mirror any window from one monitor to another. You can now show specific windows to your audience on the slide show monitor without moving the window from your primary monitor. You can continue to interact with your document window on your primary monitor. Those interactions are fully replicated live to the secondary monitor. Display Assistant works on Microsoft Windows 7 and Microsoft Windows Vista. It requires Aero effects to be turned ON. Windows Aero effects are available with the following Windows editions: Windows 7: Windows 7 Ultimate, Windows 7 Professional, Windows 7 Home Premium. Windows Vista: Windows Vista Ultimate, Windows Vista Enterprise, Windows Vista Business, Windows Vista Home Premium.
