Funciona con cualquier cosa que tenga cable por componentes me imagino, pero ha sido probado en: Playstation 3, Playstation 2, Wii, GameCube, Xbox 360, y Xbox.
Los 480i al parecer se ven de puta pena, pero al menos me servirá para configurar la consola que es lo que queria.
"Does the X2VGA 2 support 480i? What 480i EasyView functions for?
Most VGA monitors cannot display in 480i mode. The X2VGA 2 provides a simplified display of 480i with the exceptional 480i EasyView feature (patented pending). 480i EasyView however doesn't function for complete display. In order to maintain the best display while the game is playing, 480i EasyView can display 480i mode signals on VGA monitors with two limits as following:
1. You can see only a half of the full screen at one time. When you need to see the hidden part, hold the Screen Shift Button on the X2VGA 2 and the screen will move continually until reaching the part you want.
2. Some screen instability / blurriness in 480i EasyView mode when you start the Xbox system with the X2VGA 2 is normal. Don't worry, it is harmless to your monitor and will not be there once you start the game in 480p, 720p, or 1080i modes.
Since the 480i Easyview feature has the two limitations above, it is only targeted at providing convenience to a short-term use in setting Xbox on the VGA monitor. DO NOT use 480i EasyView in playing 480i games or DVDs to reduce the risk of serious injury to your eyes."
