Since upgrading to Windows 10 on my Surface Pro 3 I am experiencing a problem with my color calibration for the screen. I use a Datacolor Spyder 3 to create a ICC profile that corrects (calibrates) the colors on the Surface screen. When I rotate the Surface (going from Portrait to landscape) in my hands the screen switches back to the un-calibrated condition. Interestingly the (Datacolor) Spyder utility in the system tray continues to show the calibration on in the check box. Cycling the calibration off and then back on immediately fixes the problem. I am (so far) unable to get anyone at Datacolor to respond to this. Anyone here have any ideas?
