10 and more bits internal LUTs, DDC etc...

I know very little on the subject of LCD monitors with 10 or more bit internal

LUTs, their interaction with calibration software and DDC, their interaction

with videocards and so on.

I also noticed that there is quite a bit of misconceptions on the net about

videocard LUTs and monitor LUTs in general, as far as calibration is concerned.

Does anyone have any links to competent (but not too technical) information on

this? Like in which cases you actually do benefit from 10 bit internal LUTs, do

you always need DDC connection to benefit from them and so on.

Thanks in advance.
