    Yes, I do mind - no means "no Carnac for you!"

    Those results are due to out of the box the gamma being too high. Out of the box the unit we tested was 2.2, we got much better results with 1.8

    Wow! Thanks for the detailed table! This really great, especially the notes about the lighting conditions. :thumbsup:

    As a side note, my lighting condition with the Z Canvas was no overhead lighting, by the window, indirect sunlight. (Square 1 stays distinctly visible until ~23%, and barely discernible until ~15%.)

    What tools are you using to adjust the gamma curve (eg. Intel graphics control panel, Windows calibration, HP-provided software?)

    intel graphics primarily.

    If you are careful and both take your time and do it under neutral lighting conditions (so not under office fluorescent bulbs or home incandescent, you can get very close with the windows calibration

    What are you using to calibrate - the Windows gamma calibration seems extremely vague...

    Sorry sometimes all the various settings and controls across various platforms all blur together in my head:eek:

    Best way is through Windows display management

    Path is settings>display>advanced display settings >display adapter properties for display 1 > color management tab> click the color management button > click the calibrate display button which then gets you to a wizard that will walk you through it.

    Obviously by burying it so deep they don't want people doing it on a whim.... :)
