your report looks like the display has drifted a bit since you last profiled it. You also used generic LCD measurement mode, but this panel seems to be CCFL-based. Other than that, there’s nothing wrong from the report.
Thank you indeed for your immediate answer. I attach the html files of the last calibration tests with the advised settings The calibration is much better the colour cast is still present. Dispaycal is a great application. How to get rid of the blue tone probably visible only on my screen?
Make sure to turn off the monitors dynamic contrast feature.
If you feel the whitepoint is too cold, reduce the color temperature on the calibration tab (e.g. use 6000K instead of 6500K) and recalibrate/profile. But note that especially older TN panels are very viewing angle dependent.
