Somethings which I have discovered about the splendid BenQ monitors:
Always use the Advanced panel when Calibrating and use
Native WB (and not Adobe RGB) for your Colour space;
and choose
Relative Black Point as well.
This becomes very important if you use either Lightroom or ACR because those applications work in their own very large-gamut working space and you will get double-colour management (and horrible orange results!) if you profile the Monitor to other than Native WB.
There is a very good YouTube tutorial on the calibration of these monitors which is far better than the PME printed Instructions.

I am thrilled with my BenQ so hope that you will be with yours as well!
