My Sony DVD player, Xbox 360 and Wii can all use component cable connections for the best video picture, but my television set only has one component cable connection input, and I know that's a common problem with a lot of television sets. After a lot of online research, I discovered that what I needed to be able to hook up multiple component cable devices to one component cable input was a component video switch.
The Dynex Component Video Switchis sold at Best Buy for $45, but I was able to find a Buy It Now "open box" model on Ebay for just $18, including the shipping. The "open box" model was just a scuffed up box with a brand new product inside, no longer pretty enough for hanging in a retail store. For $18, the Dynex Component Video Switchis definitely worth it, but $45 is pushing it a little. I can connect up to 4 different A/V devices with component connections, including a Blu-Ray disc player, A/V receiver, game consoles and cable boxes, for up to 1080i resolution in the video quality. Each of the four Dynex connections also has digital audio and analog audio connections for routing sound through my 5.1 integrated amplifier with only one needed hi-fi connection. To me, that's a real convenience to not have to switch input devices on my pre-amplifier for the audio when I want to switch from watching a DVD to playing a game.
The Dynex Component Video Switchcomes with a remote control and two AAA batteries, which were already dead when I tried to install them. I had some spare AAA batteries on hand and the remote works fine. But the Dynex Component Video Switchcan also be switched manually from one device to another with just a push of a button. And, although I haven't tried this yet, the Dynex Component Video Switchcan be programmed to switch automatically whenever a video device is powered on with its original or a universal remote control, making it just that much more convenient to have in my home theater system.
