So I followed you instructions Damien and dialled the color setting down to 5000k which looks a little better, but the monitor settings were on 6500k.
If I do the callibration and this time set the Sypder to 5000k and the monitor to 5000k... the brightness is an issue.
When it gets to adjusting the brightness, even at 100% brightness on the screen that's reading 70, and the target is 120!
Tried changing the Spyder brightness from 80 to 100, still can't get within the target, and then from 100 to 120, still can't get within target..
Any suggestions how to proceed?>!
