Datacolor User to User Support Group.

My config: Spyder2Express 2.3.5, Vista 32 SP1, Intel 965 chipset

Like everyone else, I've struggled with Vista to keep the LUT properly loaded in the face of User Account Control and system sleep. I was wondering if there's a better solution than mine:

After UAC flashes my screen or a sleep, I run ProfileChooser or DisplayProfile (another utility) to first select a dummy profile with calibration data and then I reselect the good profile. If I simply double-click the good profile, or if I manually run ColorVision Startup, the LUT doesn't get loaded. (I made the dummy profile by calibrating with the red channel on my display turned all the way down, so I can clearly see when it's loaded.) This problem has occurred on two different machines with two different Intel chipsets, one with XP and one with Vista (on XP, I only had to reload the LUT after I redocked with the display).

Some questions:

1. Why won't the profile utilities reload the LUT unless I first chose another profile? It seems like either ProfileChooser, Windows, or the Intel driver is checking some id and thinking that the calibration data is already loaded into the LUT, so it optimizes away the load.

2. I see that the Spyder3 has some kind of frequent polling for reloading the LUT automatically. Will it have this same problem on the Intel chipset?

3. Is there a better way (short of buying a different computer or a Spyder3)?

4. Is there a DataColor FAQ about how to deal with Vista, UAC, sleep, etc? I couldn't find anything here or on the DataColor site.

Thanks much,

John.

1. Profile Utilities don't load LUTs, Windows loads LUTs. (Sounds a  
bit like "Guns don't kill people; people kill people...")The utilites  
just make the OS call. If Windows fails to do what is asked, and fails  
to return an error message, then we're kind of stuck...

2.  It has many of the same issues, though we keep adding more and  
more workarounds, to try to compensate for the Windows glitches, such  
as toggling profiles, checking repeatedly, not just once, etc...

3. I think you are doing the right things. Short of being so  
disillusioned that you buy a Mac, you can hope that Windows 7 fixes  
some of this. Vista was supposed to, but unfortunately the actual  
situation is worse under Vista than XP.

4. The info keeps changing, so I don't think we have a FAQ with the  
latest.
