How to connect Laptop to Projector?

How can I connect my laptop to a desktop and see on a projector?

• I have a power point presentation for school and I have Microsoft Power Point 2010 and the school has 2003 and so the effects I have won't transfer to the 2003. My teacher said to bring in my laptop and we can connect my laptop to her desktop, but we don't know if we need any wires or anything. What can i use to connect the computers? We both have a Dell. Please help

• Answer:

  Your Laptop should have a VGA out on it (If you don't know what that is do a quick google image search) and there should be a cable, usually its blue, plugged into the back of your teachers computer with the same connection all you need to do is unhook the plug from your teacher's computer and plug it into your laptop and it should work from there. That is the best possible way I can think of to fix your problem. I hope I helped, Jace
