Apparently, the "blacks" when using VGA for your 360 wasn't a deep full black... Now it is. Don't ask me what all this technical mumbo jumbo means.
LCD TVs define the color black on a level of 7.5 IRE when properly calibrated. In contrast the LCD monitor, commonly used for computers, labels black as completely black, with a zero level. LCD TVs also inherited that property when accepting signals through the VGA port, since manufacturers believed that the VGA port would usually be connected to PCs.
So while connected through VGA, the Xbox 360 still sends signals appropriated for the 7.5 IRE level of black, instead of zero. This tells the LCD that the color isn't actually black, but a lighter shade of grey. Thanks to the Spring Update, however, Xbox 360 owners have access to an IRE tweak feature that allows them to set the black level either to 7.5 IRE, zero IRE or and IRE level in-between.
