I based it on the sRGB standard, which - if I'm reading it right - specifies a gamma of 2.2 and white point of 6500K (for all monitors, LCDs and CRTs). I've read that a gamma of 1.8 is traditionallly associated with Apple monitors in the CRT era.
This is a vendor-published whitepaper, but it looks like a good basic intro to the issue:

i set my crt to 2.2 also but after i calibrate the LCD with the spyder, the 1.83 looks much more natural than 2.2. if i bring the gamma up to 2.2, i start losing blacks, the whites freak out and the picture looks very unbalanced...
i've never heard of calibrating an LCD to 2.2, because of the lack of blacks in LCD's, you need a lower gamma so the blacks dont turn to dark greys.
maybe its just THIS monitor
