I have binned the spyder calibration and gone back to the original, a greyscale ramp in that shows a very small change in contrast when I switch to monitor rgb, before everything was magenta, even the greyscale image.
The instructions are pretty simple with the spyder, I followed the boxes on screen, applied the spyder to the screen box, and updated after every colour ajustment. It just kept on telling me I needed more and more red all the time, even when it looked wrong to the eye.
When it finished and showed the before and after I was horrified, for a minute I though I was looking at the wrong version, the test image looked really red in the after version, the before looked fine.
Thanks Wayne
