Rendering black on a monitor is like telling a musician to play silence, the silence only exists as a lack of anything else, likewise with black on a monitor, it's the lack of any colour that makes black, think of each pixel in a monitor as a light bulb, when you want black the lights are turned off, the persistence is the time it takes the light's fillament to cool and stop glowing, so without that low persistance monitor you cannot get to black any quicker, unless you start from a darker colour Hope that makes sense Jeremy -- ________________________________________________________ PGP key is here -> http://www.computerbooth.com/pgp.html * If debugging is the process of removing bugs, then programming must be the process of putting them in.
