alexreed88, 18 bits encode 262144 colors, not 16 million. Where did you pull your numbers from?

I strongly doubt that you can tell the difference between 18 bit color and 24 bit color, or a difference between two frame rates if the lower one is at least 30.

And yes, you will lose any debate based solely on perception and motivated by insecurity, lack of knowledge, and vanity. In fact, both parties entering such a debate will.
