Sometimes even the biggest television screen isn't quite big enough. If you're an avid home video game player, this is especially true. You can hook up your Sony PlayStation 3 video game console to a video projector and display your favorite games on a screen far bigger than what you would experience on the biggest TV that money can buy, or even on the wall. To make this connection work, you'll need to plug a special type of video cable into both devices.
Plug both your Sony PlayStation 3 and your home theater projector into wall outlets, but do not turn either device on yet. Due to the large amount of power that both a PS3 and a projector will draw when on, you may want to plug the two into a surge protector or power strip for safety.
Connect one end of a standard HDMI cable into the output that is clearly labeled "HDMI OUT" on your Sony PlayStation 3. The output has one flat edge and one curved edge and is located near the right fan vent on the back of the PlayStation 3's case.
Plug the other end of this HDMI cable into the "HDMI IN" input on the back of your home theater projector. This input will have the exact same shape of the output that was on the back of the PlayStation 3. Your Sony PlayStation 3 and your home theater projector should now be physically connected to each other via this cable.
Turn on your projector. Let it power up for a moment.
Turn on your Sony PlayStation 3. To do this, you can either press the "Power" button on the front of the console or push the button on your controller with the "PlayStation" logo on it. The image from the PlayStation 3 will now be displayed on your screen (or your wall) via the projector.
If your Sony PlayStation 3 doesn't turn on when you press either the button on the front of the unit or the "PlayStation" button on you controller, make sure the "Main Power" button on the back of the unit is "ON." This button is on the far right side of the console, just above the input for the power cable.
