Just got a spyder3 pro. When I try to calibrate my laptop led monitor, it suggested a reading of 180cd but when I try to press the brightness button on my laptop up and down, I am unable to match the exact value of 180. After which spyder reverted to a lower reading below 180cd. ANyone encountered this b4 and any advise or recommendation ?

Thanks in advance.
