I have been testing the BenQ SW270c and was impressed by the brilliance of its colors and the speedier calibration process compared to the predecessor the SW2700PT - thanks to the USB-C connection. However it is still very slow - at least 10 times slower than Color Navigator!
What bothers me most - and a colleague of mine too (2 monitors tested) - is the fact that when working on BW/grayscale images there are magenta and green casts in the lighter tones, stripes as you can see in the attached image. This is easily visible in a gradient - less in "normal" BW images. If the image is moved on the screen, the stripes move as well so not an uniformity problem.
We have used the i1Display Pro and the BenQ Palette Master, latest version on both macOS HighSierra and Windows 10. With the i1Profiler 3, the problem gets even worse.
In Palette Master only the Matrix profile setting is working reliably, using LUT 8/16 settings does normally fail when validating the calibration result.
Does anybody see this effect too - and if not, what are your settings/tools that may help? BenQ support seems to be aware of the problem but could not help us so far.
Thanks for your help, Markus
