I have a presentation I am supposed to do next week and thought I would use some pictures on my computer as part of the program. I need to project them onto a wall or screen - but have no idea what I need to be able to do this. I have two laptops - HP Pavilion 9000v and a Dell Studio 1749. The HP is about 4 years old. The Dell is not quite a year old. Can you help me get started on researching if either of my computers have what it takes?
