If you've got a new DLP projector, you may want to link it directly to your home theater system. Many home theater systems now use the home theater audio receiver as a hub for both video and audio. Since receivers have built-in video switching, you need only change the mode on one device to switch from TV to DVD or a video game, rather than adjusting the mode on your receiver and your TV. Connecting a projector directly to your receiver continues this line of thinking, which is especially helpful if your projector is mounted on your ceiling and you've lost your remote control and can't change its video mode.
Determine which type of video inputs your DLP Projector has. The ideal choice is an HDMI cable, as this is a single cable which transmits a high definition signal. This will be a flat, rectangular port. Second in line is the component video cables. These also transmit an HD signal, and are three round ports color-coded blue, green and yellow. Finally comes the single-port S-Video input. This transmits a digital non-HD signal, is round and has four pin-sized holes in it.
Determine which type of video outputs your receiver has, then select the best connection available.
Video of the Day
Connect your receiver to your DLP projector using the cord you have selected. Insert the ends of the cord into the ports snugly. However, be careful with the S-video cable: It is extremely easy to bend the pins inside the ends of the cable.
Turn your receiver on. Set your DLP projector to auto-detect mode, so it can find your receiver and display the video projected from it. If this doesn't work, press the button on the projector or remote to change the video modes. Check your projector's manual for more information.
