Calibration, part 1

I have worked with two monitors for a couple of years. Different brands and therefore hard to calibrate to the same colours and one of them started to shift in colours. In January I bought two new identical monitors and they are “hardware calibrated”.  After two months they both announced, “Your monitor needs to be calibrated”. OK, but my old calibration device was too old, so I had to buy a new one.

After half an hour of work this evening, this is the result….

Anyone with similar experience?
