I have been using Huey for a while on my PC. With the software it would just load the profile automatically with no problem.
Lately I just got a laptop and I wanted to calibrate its screen too. After running the software, "corrected" and "uncorrected" looks the same to me, and so does all the other presets. On my PC I can see a distinct difference in color temperature and contrast among the various presets.
I opened up Windows "color management" screen and the Huey profile wasn't selected, I manually selected it but the screen still looks the same.
It's a noted 'bug' particularly with Nvidia cards, though ATI cards do suffer from it somtimes it's down to the UAC preventing the loading of the profile or the LUT table is reset upon reboot/reset by the gfx divers. It may have been solved with SP2 or newer device drivers.
It can be more of a issue under x64 than x86 Vista.
Oops, the laptop in question is running Vista 32 bit SP1, graphic is Intel GMA X3100.
The PC which is working fine is Vista 64 bit running some nVidia card that I don't remember.
FWIW, the laptop render tonal gradation on external display (a TV by HDMI) horribly. I used the PC on the same TV which worked fine. On the laptop screen it looks pretty ok.
I'll try the ProfileMaker.
Edit: ProfileMaker says "This profile contain a vcgt tag, but I could not activate it, because I don't understand it (see list of known bugs)" and could not load the profile or any other profile for that matter.
I worked through my problem with Vista 64. It appears that Vista overrides the calibrated profile soon after start-up. I used this program to delay the loading of my Optix XR profile for 15 seconds after start-up. It solved the problem. You just drill down through your program files until you get to the gamma loader. I read that someone did something similar using the task manager, but I had already solved it with this software. Make sure that there are no competing gamma loaders installed, such as Adobe Gamma. Do a search on your computer for the word *gamma
I read about somebody who made a profile using a piece of colored cellophane or something between the puck and the screen. Of course, his profile was way off in color, but then he knew exactly when it was being loaded and when it wasn't.
