I was wondering the same thing about my Benq 2700. The included software is supposed to write a 14 bit profile into the monitor itself. But it also allows an option to write the profile system wide - into the Windows color management folder as an icm monitor profile I'm guessing
Which on it's own is kind of confusing - can win 7 deal with a 14 bit profile? Plus you get the option of making the profile v2 or v4.....A v4 profile from the Xrite sw didn't play nice in win 7. The manual isn't clear about anything regarding the system wide setting, or why it's an option. I kind of thought the Color Pallet sw would have reset the system graphics card lut and then calibrated the panel's internal lut. That doesn't seem the case? Can anyone shed some light on how these panels with internal luts work?
