As far as I know the Pantone Huey Pro works like this: First it tries to get the most out of the monitor by manipulating the color lookup table of the graphics adapter ("correction") and then it provides a display profile that describes the display in the corrected state.

Unfortunately enabling the correction screws up the colors in other applications, especially when I tilt back the screen. Because of that I usually turn on the correction when I work with images and switch it back off when I return to regular work.

I am willing to sacrifice some linearity when I can avoid switching it off and on all the time. Can I use the Huey to create a display profile that describes the uncorrected state of the display?

    If you are having this much of a change by tilting the monitor back, it sounds like you need an IPS panel. – dpollitt Oct 10 '11 at 0:01

    Yes, IBM calls it "Flexview" and my old T42 had it, but apparently there are no T series Thinkpads with Flexview any more (this is a T520). I miss it. – AndreKR Oct 10 '11 at 0:14
  • My question about color management in Linux is basically asking about the same thing, and although I don't think it provides an answer for the MS Windows / Huey software, it may provide useful background for understanding what's going on. – mattdm Nov 7 '11 at 21:50

Calibration kit like the Huey Pro measure colours displayed on your monitor to build a colour profile. Colour correction then uses this profile to get the colour right on your monitor. Because of this fact it is mandatory to have colour correction turned on when using these devices.

  • This doesn't make sense to me. So you mean, there actually is an internal profile that describes the monitor before color correction? – AndreKR Oct 19 '11 at 10:09
  • @AndreKR: There are generic profiles for things like CRT monitor or LCD monitor which ship with the OS. These provide a rough approximation for a particular class of device. Monitor vendors usually ship a profile with a monitor these days which gives a closer approximation for the panel the monitor has. Heuy Pro gives an exact profile for the actual device tested. – Paul Round Oct 19 '11 at 11:59
  • Yes, but that exact profile is valid only when color correction is on. I want an exact profile for the device with color correction switched off. – AndreKR Oct 19 '11 at 15:56
  • @AndreKR: unfortunately that's the big problem the profiles are the data used by colour correction. With it off there is no correction at all, not even the generic profiles are used you just get the raw RGB values sent straight to the device so lots of inconsistency across devices. – Paul Round Oct 19 '11 at 18:25

    Take a look at photo.stackexchange.com/questions/14585. I assume a similar thing applies in the case of the Huey software, and that what Andre is asking is to have "null" Video LUT (or whatever the equivalent is), and have the XYZ matrix used by color-aware applications be specified as working from that "uncorrected" starting point. – mattdm Nov 7 '11 at 21:46
