Dell LCD hidden service menu and advanced settings help needed

[JAC]

For those who didn't know, Dell provides consumer access to a hidden service menu providing more advanced information and settings, such as the full model number, monitor chip-set, total time used and advanced color options. This menu can be accessed as follows:

1. Powering off your screen
2. Holding down MENU and + buttons while powering it on
3. Release those buttons and enter the MENU
4. Select FACTORY RESET
5. Scroll down to FACTORY

Now, who knows what all the settings in there mean?

Auto Color
Clear User Area
Sub-B
Sub-C
Offset 1
Offset 2
Gain
R, No
R, Val
W?
A
P

I've also noticed that according to Dell's specs, the sync polarity for 1680x1050 should be +/+, but according to the Advanced Timing settings section of the Nvidia control panel, it's set to +/-. Should I change this?

Much obliged,
JAC

bump for OP, I'd like to know too.

Some may find this interesting. It's a spreadsheet that calculates the Vesa Coordinated Video Timings for any given resolution. Turns out the Dell spec of +/+ polarity is a typo.
