Kyle,

I'm not sure I have the answers to all your questions.

First, Firefox has a free Add-on (Tools > Addons > Get Addons, then search for Color Management) you can install that activates color management when browsing with Firefox. You need to specify the profile you will use for color management, so you may only have color management on one monitor.

My video card is a Matrox Parhelia card, and has three monitor ports, but only 1 LUT, and only one of the connections is digital. This means the one LUT is applied to both monitors. I use the dig connection for my main monitor, and the analog connection for the 2nd one.

So, I calibrate my 2nd monitor (which I use mainly for palettes and email) using the analog connection to my video card. This enables all the color controls on the monitor, so I adjust everything manually. I use Gretag's free DisplayProfile.exe (PC utility) to load the profile for each monitor. It seems to work fine. I load the palette monitor first, then the main monitor second, each having its own profile. I use the digital connection for my main monitor and set it as the system profile. I know the utility works for PC's and with Gretag software. Not sure if it works with XRite software, even though XRite now owns Gretag.

First, it looks like you have two CRTs, so all the controls on the front of your monitors are probably analog. This allows you to calibrate your monitor to get it mighty close to your target settings, even before anything is written to the video card. So, even if the LUTs are left alone, you should be close to start. Second, you said your video card has two LUTs, so each monitor should remain color managed at all times once they are calibrated and profiled. LUT1 will have curves specific to CRT1, and LUT2 should have its own curves set to correct CRT2.

Some of this is speculation, since I don't have a similar setup. In fact, I am not sure why DisplayProfile.exe allows me to load separate profiles on my two monitors, since my card has only one LUT, but it is clear that it works. My monitors match fairly closely, and invoking the wrong profile on the wrong monitor definitely whacks it out. So, for whatever reason, it seems effective.
