Precision 7760, terrible color experience

You had originally replied to a thread concerning the XPS 17 9710 UHD 3840x2160 LCD. Your Precision 7760 uses a different FullHD 1920x1080 LCD. The pictures of your Precision 7760 LCD BIST (Built-in Self Test) show that this LCD meets our manufacturer specifications.

Of course every external monitor connected to the Precision 7760 will have to be color calibrated using 3rd party calibration hardware (colorimeter) and software.
