When you see the IRE #, it'll say 100, 90, etc. On the CNET settings the 1st number is your IRE #. The numbers in parenthesis are your RGB. So set your IRE# then scroll down and set your individual RGB numbers. For instance 100 (-5, -20, -55). The next setting will be 90 (so scroll back up and change the IRE to 90), then the RGB settings for it parentheses... and so on. You keep doing this until you get to the end (the last IRE #).
Before you start moaning, another nice feature with this set is the ability to port your settings to EVERY input so you dont have to keep re-entering them. VERY nice feature.
I use the CNET settings for pretty much everything and just adjust backlighting, TM, RC, sharpness, dynamic contrast, etc. Be aware, it's designed for a darker room though, so in light environments some blacks may be a bit washed and things may look blue.
