matt, you have to read that article and try to understand what is happening within the program, which may or may NOT have anything to do with what you are trying to see in your understanding of " preview" on screen... sorry but the tech stuff in that article kinda explains the color ranges described by the number of bits ( 0 to 255 for 8 bit for example ) and how it relates to 32 "floating" bit. Maybe you could try to describe better what you want to see using what you are using right now ? It may be that you are talking about something else ( like what you see in your monitor after you render something ? ). I'm not sure what you are really looking for.
And, yes, you do have to turn on maximum bit depth in order to achieve what the article is telling you about depending on what your source is and what your output is going to be ( see article toward bottom re: different types of source material ).
I have a sneaky suspicion that you are really just looking for a better looking 'color' on your monitor after you render your timeline or something.???
