I've been tearing my hair out trying to convince BenQ that they have a problem with the profiles generated by Palette Master Element (PME) on the SW2700PT (but it may affect other models). To me the problem is immediately apparent if you calibrate and profile to a non-native gamut, but BenQ insist all is correct. Please could other owners take a look at this.
If you have a more recent monitor (manufactured after about October last year) you should see an option in PME to calibrate and profile to RGB primaries other than the native gamut. Try calibrating to sRGB primaries, then use the calibration with the sRGB profile created by PME. On my system the images rendered by colour managed applications appear very de-saturated. The reason is, the profile has been created for the native gamut, not the sRGB gamut. In fact, I think PME always creates a profile for the native gamut, regardless of the calibrated gamut.
The calibrated gamuts appear to be correct (ish). It's the profiles that are wrong.
I said the calibrated gamuts appears to be correct (ish). I doubt the sRGB calibration uses the correct sRGB gamma curve, but it's pointless taking that up with BenQ when they can't understand their profiles are wrong.
I also have a problem with PME if I attempt to calibrate to Relative Blackpoint. At the end of calibration it fails with a white background programmed into the LUTs.
I'd appreciated if SW2700PT owners could spare the time to check if they have the same problem with the sRGB profiles and calibration to Relative Blackpoint. Perhaps BenQ would start to take note if a few more of us reported the issues. There again!
