How to Set Up a Computer to a Projector
If you have a newer video card, you probably already have a second video out port. Laptops usually come with a video out port on the back. If you don't have a second video out port, you can always buy a splitter. A splitter will split a cable from one port into two, just make sure you match up the type DVI or VGA.
Instructions to setup projector
1). Turn your computer off.
2). Connect the cable from the computer to the projector. If you want to have your monitor to be hooked up as well, connect a splitter to the video out port (DVI or VGA). You can also just hook the projector up to the second port on your video card (If you have one) or if you have a laptop, you can connect to the video out port on the back.
3). Turn the computer.
4). Turn on the projector. Most projectors have an auto detect function, that will detect a video signal and auto configure the projector to display that signal. If you have a laptop, you have to hit a function key to activate the second display. Usually this is FN Key + F5 or one of the F Keys across the top of the laptop keyboard. It looks like two squares, one empty and one with something in it.
5). Adjust the focus, brightness, contrast, and color on the projector.
6). Aim the projector at something white. Try not to aim it at something highly reflective.
7). Step back, load up your favorite game or video.
