When you give a lecture or make a speech with computer and projector, Presentation Aide will greatly help you. The second monitor(projector monito) can mirror the first monitor(your computer monitor) synchronously , but, without something such as Presentation paper window and a Memorandum window. So, you can see something prepared in the first monitor, but audience can not see them in the second monitor! Please visit www.vaysoft.com for detail!
